How Many Drops of Essential Oils Should I Put in My Diffuser?

Diffuser Size Number of Drops
100ml 3-5
200ml 6-10
300ml 9-12
400ml 12-15
500ml 15-20

The most important thing is not to use too much of any essential oil. These oils are typically highly concentrated, meaning that a small amount of essential oil can release a significant amount of fragrance.

You don’t want to overwhelm the area with fragrance. Any scented product, including essential oils, can be an irritate if it is inhaled. You are aiming for a slight hint of scent, rather than a dousing.

The usual amount of water held by a diffuser is 100ml, and typically it is recommended to add 3-5 drops of essential oil per 100ml of water. Of course, the amount you choose to add will vary according to personal preference, as well as the size of the room – larger rooms will benefit from slightly more oil.

Diffusers do come in different sizes, but these are usually in 100ml increments, and therefore calculating the number of drops of essential oil to add is relatively easy. The smallest, 100ml diffusers will take 3-5 drops on average, while the largest, 500ml diffusers will require 15-20 drops.

Signs That You’ve Used Too Much Essential Oil

If you feel any of these symptoms, this means that you might be heavy handed with how much essential oil you’re putting into your diffuser.

  • Headache or migraine
  • Dizziness or vertigo
  • Nausea
  • Vomiting

If it’s your first time using essential oils or pairing them with a home diffuser, the rule “less is more” should guide you. Start with less drops first and then adjust the amount later on to suit the size of your room and your individual taste.

How to Use A Diffuser

It is generally recommended to place a diffuser on a high shelf, in order to allow for maximum dispersal.

All diffuser models vary, but, in general, they are relatively simple to set up.

  • Remove the lid of your diffuser
  • Fill it with water to the fill line
  • Add the recommended number of drops of your preferred essential oil
  • Screw the top back on firmly
  • Place the diffuser in a suitable location in the room

How Many Drops Are In 10ml?

There are 200 drops in a 10ml bottle of essential oil. This means you can get an approximate 40-65 uses out of a 10ml bottle of essential oil if you’re using a 100ml diffuser.

You can typically purchase essential oils in small bottles that come in 5-15ml bottles. However, some types come in bigger bottles ranging from 30ml (1 ounce) to 120ml. Here are the number of essential oil drops there are in each bottle and how many uses you can get out of your purchase.

Important: This table shows computation for a typical 100ml diffuser.

Volume (ml) # of Drops # of Uses
5 ml 100 20-33
10 ml 200 40-65
15 ml 300 100
30 ml (1 oz) 600 200
120 ml 2400 800

Essential Oils – What Are They Used For?

Essential oils are often used to aid in sleep, relaxation, or even rejuvenation usually in a diffuser, as not all oils are suitable to be used on the skin.

Diffusers work by warming up the oils, often using hot water, causing a delicate, subtle fragrance to spread around the room.

Different scents are held to promote different states of mind – for example, lavender and sandalwood are relaxing and can induce sleep, whilst citrus scents are energizing and stimulating.

How Many Drops of Essential Oils to Add to Lotions

Essential oils can make a great addition to fragrance-free lotions, and can add an extra touch to your pampering regime.

When blending essential oils with lotion, the recommended ratio is 3 drops of oil to 10ml of lotion, although, again, this can be varied for personal preference.

This is also a good ratio to work with when blending essential oils with carrier oils such as grapeseed and jojoba for massage.

Pro-Tips and Warnings

  • Essential oils should not be used directly on the skin.
  • You should not drink essential oils, or use them in food.
  • Make sure your room is well-ventilated when diffusing essential oils to avoid headaches.
  • If you have high blood pressure, do NOT diffuse for more than 60 minutes. It can aggravate your hbp. Pregnant women and diabetics should exercise the same caution.
  • The best way to enjoy diffusing essential oils is to add them fresh to your diffuser each time.
  • Change out your water and clean the bowl every couple of days.
  • Mixing heavy essences with lighter ones is good practice. For example, mix frankincense with orange.
  • Essential oils are most effective when diffused through heated water, or blended with fragrance-free lotions, and carrier oils such as jojoba or grapeseed, and then used as part of a massage or pamper regime.

You have this fancy new device that everyone told you about, and now you have no idea what to do with it. Question number one is always how many drops of essential oil go in a 100 ml diffuser?

Don’t worry you aren’t alone! A lot of people new to essential oils and diffusers have these questions and we’re here to answer them.

Step One: Diffuser Setup

While most boxes will instruct you to use tap water it isn’t the best choice or your system. For long-term system health, use filtered water.

Why? Well, this drops the rate of build-up that you’ll eventually see in the diffuser.

Much like a humidifier, there is a lot of water going through a small, heated, device. This means that the cleaner water you start with, the cleaner your diffuser will stay!

When you’re setting up your diffuser there should be either a fill line or a cup with a fill measurement. Load it up with water and plug your diffuser in. The hard part is already done.

Really the greatest thing about diffusers (next to all the great environmental benefits from essential oils) is that they are so easy to operate. It’s a treat to just pour some water in, and turn on a system for a great boost to the room.

Step Two: Adding Essential Oils

Alright, you have your water added and your device plugged in. What now? We go right back to our first question.
How many drops of essential oils do you put in a 100 ml diffuser? This is one of the more common sizes and even more popular for the starter sets that are available.

The Number of Drops Range

DoTerra, one of the leading names in essential oils and diffusers says the go-to number of drops of essential oils in a diffuser is between five and twelve.

Doesn’t that sound like a really big range? It did to us.

So we did some digging and it seems like there is a wide range of how many drops to use. But, we found some reasoning behind this wide variance.

First and foremost think about the size we’re talking about here. A 100 ml diffuser is usually the introductory size, so we recommend starting with three to five drops of your favorite scent.

Now, the primary aspect to take into consideration is that not all essential oils have an equally strong scent. I don’t know about you but if I can’t smell it I sit around wondering if it’s working.

For strongly scented oils like peppermint or lemon, a little goes a long way. Three drops are sure to do the trick and one or two extra might be too much.

If you’re using weaker scented oils like lavender or eucalyptus we recommend kicking that drop count up to five and maybe even six. Just because an essential oil doesn’t have a strong scent doesn’t mean it doesn’t have benefits.

Step Three: Clean Between Oils

There are a few ways to clean your diffuser. If may seem like its only water and some good smelling drops of oil. What could be the harm in not cleaning it?

Diffusers, as beneficial as they are, can be breeding grounds for bacteria. Also, without regular cleaning, they can start a buildup of grime from the water level sitting between being turn on or refilled.

Cleaning is also a great way to switch oils and be sure that the oils you’re using aren’t mixing in an unpleasant way.

Method one: Gentle Dish Detergent

That’s right folks, a simple drop of dawn and warm water can clear out the potential gunk in your diffuser. Start by unplugging it, emptying any water left in there and then grab a sponge.

This is a simple and fool-proof method for cleaning your diffuser. It is also a great practice to keep up whenever you need to refill your diffuser.

When you’re done, wipe everything down with a damp cloth. Then, start looking for the mist chip.

The mist chip is a little chip that is inside the water tank. Unlike the rest of the diffuser, the mist chip needs to be swabbed with a q-tip that has a bit of rubbing alcohol on it.

It’s a bunch of technical talk explaining why the mist chip needs to be wiped down with a cotton swab or q-tip. So the long and the short of it is that this little chip, although in the water tank, can sustain water damage.

The q-tip or cotton swab with alcohol prevents that.

Method two: The Deep Clean

So, you didn’t clean the diffuser regularly (you’re not alone!) and now it is kind of gunky. Yes, it is a little gross and you’ve been breathing in that gunk for a while.

But you can fix it! Starting out, setup your diffuser like you were going to use it and only fill the water tank about halfway. Then add a teaspoon of pure, distilled, white vinegar.

Let the diffuser run for about fifteen minutes, and then unplug it and empty the vinegar water. Use a cotton swab to wipe down and dry the inside of the diffuser.

Using a cotton swab here will also let you attack any grime that stuck onto the sides. Be sure to hit that mist chip in the same way you would in method one!

Step Four: Continue to Enjoy!

Continue to enjoy your diffuser regularly. With a clean and properly, (essential) oiled system, your room and your nose will be thankful for the bit of work these require.

If you find yourself stuck on how many drops to put into a 100 ml diffuser keep this in mind. It is always best to start small, with three drops and work your way up to five or six as needed.

How Many Drops of Essential Oil Should You Put into a Diffuser?

I remember when I first got my diffuser. And how excited I was. But, before using it, the very first thing I had to google was how many drops of essential oil to put into a diffuser. So, I thought I would write an article on how to do just that. Why?

This blog is supported by readers purchasing featured products. When you buy products with my links, I earn a commission at no extra cost to you. Here is my full affiliate disclosure.

Well, first, essential oils can be expensive (sometimes even $100 per bottle). Thus, you don’t necessarily want to waste your money by adding an unnecessarily large amount of oil to the diffuser.

Second, the fragrance might become so overwhelming, you’ll need to open your windows and waste all that goodness. Also, you might irritate your nostrils.

Third, while there is a common misconception that you cannot be allergic to essential oil, it’s not true. Studies show that essential oils CAN CAUSE allergic reactions.

Thus, adding too much oil that you’re allergic to, can cause health problems too. Some of the most common essential oils that can cause such reactions are: Bergamot, German chamomile, Ylang Ylang, Geranium, Tea Tree and even Lavender.

Diffusers come in different sizes. However, the smallest ones are usually 100ml. Here’s approximately the amount of drops you’ll need for diffusers of these sizes.

  • 100ml: 3-5 drops
  • 200ml: 6-10 drops
  • 300ml: 11-15 drops
  • 400ml: 16-20 drops
  • 500ml: 21-25 drops

So, the saying – the more the merrier – doesn’t really apply here. If anything, I recommend starting small, and see how you feel about the fragrance in your home.

Thus, instead of adding 5 drops to a 100ml diffuser, add 2-3 instead. It’ll be much easier to figure out how fragrance spreads across your home that way. You’ll save the essential oils too!

If the holidays come, and you want to try some of the holiday essential oil blends make sure you still stick to the water and essential oil ratios mentioned above. So, do have in mind that you might need to adjust the recipes a little bit.

How Many Drops Are There In a 1ml?

There are approximately 20 drops in a milliliter of essential oil. Here is how many drops you can get out of these essential oil bottles:

  1. 5ml bottle – 100 drops
  2. 10 ml – 200 drops
  3. 15 ml – 300 drops
  4. 20 ml – 400 drops
  5. 30 ml (1 oz) – 600 drops
  6. 50 ml – 1000 drops
  7. 100 ml – 2000 drops

So, How Long Will a Bottle of Essential Oil Last?

That’s a question you should probably ask yourself each time you’re buying new oil. Especially if you want to estimate how much it will actually cost you to diffuse it one time.

While smaller bottles cost less, investing in a bigger bottle might end up being cheaper in the long run – since you’ll be able to use it for many more times.

Here’s how many times you can use a bottle of volume X if you have a standard 100ml diffuser:

  1. 5ml: 20-30
  2. 10ml: 40-65
  3. 15ml: 70-90
  4. 20ml: 80-120
  5. 30ml (1oz): 150-200
  6. 50ml: 250-350
  7. 100ml: 400-600

How to Know When You’ve Added Too Much of Essential Oil to the Diffuser

Here are some of the most common side effects you might experience when you’ve overdone it with the essential oils:

  • Headaches
  • Nausea
  • Vomiting
  • Irritations
  • Dizziness

If you happen to live in a small room and use a strong diffuser for a large space, you might end up feeling sick even if you’re using the right amount of drops.

Thus, always start small and see how the fragrance fills up the room.

How to Use a Diffuser

Tips and Facts About Diffusing Essential Oils

1. There is more than one way to diffuse essential oils. Read more here.

2. Diffusers require regular maintenance. Thus, don’t forget to clean them!

3. Never use essential oil without diluting it first.

4. If you’re breathing in the vapor to heal a cold (which you can do by the way) make sure to close your eyes. Essential oils can severely irritate the eyes.

5. When diffusing essential oils around babies or toddlers, make sure to use the smallest doses to avoid any possible allergic reactions or other irritations.


When it comes to using essential oils, always remember that less is more! Start small, try out different essential oils to truly test what strength of fragrance you find calming and pleasant.

Each essential oil might act or feel differently. Thus, always start with lower doses and only then add more drops! Anyway, enjoy the benefits of aromatherapy and the smell!

A gorgeous scent in your home makes your space warm and inviting. Nothing could be better than choosing some of your favourite fragrances to make your house smell elegant. We spend our hard earned money on purpose made home fragrances, but I do not feel these match up to the pleasure we can get from using a wearable scent.

Can I Use Perfume In A Reed Diffuser? Yes, it is perfectly possible to use your own perfume in a reed diffuser. You will need a high necked bottle to house the fragrance, 6-10 reeds to diffuse the scent, a carrier oil, and your preferred perfume. Either ‘eau de parfum’ or ‘parfum’.

Scenting a room with your favourite fragrance is not only a heart-warming way to vary how you use your scent but is also a great way to analyse the different notes each fragrance has without the added complexity of the perfumes reaction to the chemicals and oils in your own skin.

Let’s now investigate how you can make your own room diffuser using your own perfume. It’s interesting to explore how the top and mid notes give way to different base notes in a neutral environment without reacting to your own skin.

How To Use Perfume In A Reed Diffuser

Equipment Overview

  • 1 diffuser bottle
  • 6 – 10 rattan or bamboo reeds
  • Your chosen perfume
  • Fractionated coconut oil (carrier oil)

The Diffuser Bottle

Diffuser bottles are available online at Amazon

Firstly, you will need to gather the correct equipment, A small bottle with a narrow neck opening is ideal for making a reed diffuser. It should be sturdy enough to hold the reeds and a smaller neck opening is best to stop the perfume from evaporating too quickly.

You might find you have some old perfume bottles that will be perfect for the job, or an empty reed diffuser bottle. Alternatively you can purchase a reed diffuser bottle to save you searching every cupboard, the reeds in this example are not included.

The Mixture

Fractionated Coconut Oil is the ideal ‘carrier oil’

Along with your chosen perfume you need a ‘carrier oil’ to carry your perfume up the reeds. Fractionated coconut oil is ideal as it is a pleasingly light colour. Thicker oils won’t travel up the reeds properly and dark oils can look unsightly. A massage oil or baby oil can also work well.

Some home-made reed diffuser methods call for perfumer’s alcohol or rubbing alcohol but you should find this is already included in your perfume. You could add a little if you find your perfume doesn’t have enough for the scent to carry or last very well.

The Reeds

Rattan Reeds carry the fragrance

Last but not least, you will need some clean rattan or bamboo reeds. Don’t be tempted to reuse old reeds as they may carry the scent from your old room fragrance and they won’t work as well once they are already saturated. They need to be at least as long as your chosen container so that plenty of reed meets the air to allow the fragrance to disperse.

How To Do It

Step #1

To figure out how much liquid your diffuser container can hold. Fill it 3/4 up with water, then pour that water into a measuring jug to see how much is can contain. For the rest of this guide we will presume 100ml

Step #2

Into a separate small mixing container, add 2/3 carrier oil and 1/3 of your chosen perfume (eau de parfum or parfum) to make 100ml. You can add more perfume if you find it is a light fragrance

If using the magic of Google you find your perfume does not contain alcohol (most do contain alcohol), then add an additional 20ml of perfumers alcohol to your mixture.

Step #3

Gently mix but avoid stirring too vigorously or you will cause the perfume to evaporate and lose strength in the top notes before you even add it to your bottle.

Step #3

Carefully pour your mixture into your chosen container.

Step #4

Add the reeds and spread them out in a fan shape to encourage the scent to disperse into the environment.

Step #5

Place your diffuser somewhere well ventilated to help the scent carry throughout your room.

What Perfumes Work Best In A Reed Diffuser?

The best perfumes for reed diffusers are eau de parfum or pure parfum as these contain the highest concentration of fragrance oil.

Eau de toilette is not recommended. It can be heavily diluted which will mean there won’t be enough fragrance oil for the diffuser to work effectively. Instead, it will evaporate very quickly and leave very little actual fragrance behind.

Similarly, a perfume that contains mostly top notes will work nicely at first but once those short-lived accents have evaporated, you might be left with little or no scent at all.

If you want a room diffuser to last, you need to select a perfume that is rich in base notes as these will continue to permeate the reeds and fill up the room with gorgeous fragrance that will last as long as possible.

Can I Use Up My Old Perfumes I No Longer Wear?

We all have several bottles of perfumes on our dressers that we used to love but find we no longer wear, either because our tastes have changed, we have fallen in love with something else, or they have lost their original appeal.

Creating beautiful reed diffusers can be a fantastic way to use up those perfumes you once adored but no longer have the chance to wear. Because perfumes smell differently on our skin, you might find that even something you don’t like very much when you wear it can be make a delicious room fragrance.

Making your own diffusers is a great way to experiment with different fragrances that produce a totally different effect when used in a diffuser. If, like me, you like to collect some testers or samples this can be another great way to use perfumes that you wouldn’t normally purchase for yourself. It’s also a good way to use any unwanted perfume gifts you have been given that you don’t particularly like to wear.

What Is A Reed Diffuser?

A reed diffuser is quite simply a bottle filled with your chosen fragrance and rattan or bamboo reed diffuser sticks. The sticks need to emerge from the top of the bottle by several inches or more.

As the reeds sit in the fragrance, the carrier oil travel up the sticks, taking the fragrance with it so that the scent gently evaporates into the room. Over time, the base of the reed sticks will become saturated and you need to turn them to allow more fragrance to travel to the top.

If the reeds are too short, you will find that not enough fragrance reaches the top to evaporate effectively enough to make the room smell. If the reeds are too long, the fragrance might have completely evaporated before the oil reaches the top.

Arranging your reeds in a fan shape is the best way to make sure the scent is dispersed as broadly as possible and you can use a simple ribbon tied in a bow to help them keep their shape if the neck of the bottle is wide and doesn’t fully support them enough.

How Does A Reed Diffuser Work?

The rattan reeds are permeable which means they absorb the liquid around them. As they sit in the liquid perfume, the reeds gradually soak up the oil so it travels to the very top of the reed. Once the perfumed oil meets the air at the top of the bottle, the perfume in the oil begins to evaporate and is gently released into the environment.

Because the reeds are very porous, they continue to absorb more and more perfume to replace what has already evaporated and in doing so, they continue to emit gorgeous fragrance until the perfumed oil runs out.

Reed diffusers are a great alternative to scented candles or plug-ins as there is no risk of fire, no soot, and no potential for electrical malfunction. They simply continue to work naturally, without posing any risk to your home.

What Are Essential Oils?

Most of the reed diffuser sets you can purchase use stronger essential oils due to their durability. Many people use a particular essential oil that they select to add a certain fragrance their own diffusers.

Essential oils are extracted from plants and concentrated to capture their flavour, scent, or essence. They are the extracts used to create most perfumes as they carry the fragrance from the plant and can last a long time.

Essential oils have been extracted from plants or flowers. Extraction methods can include compressing the plants until the oil is released or using high temperatures so that the oil is distilled. As you might imagine, each plant is only able to release a tiny amount of oil which is why so many flowers are used to create the essential oils used in perfumes.

Most perfumeries own massive fields where they harvest their own plants and flowers in order to extract the oils to make their perfumes. Up to 700 roses can be used to create a small 15 ml bottle of perfume, which is one of the reasons why perfume can be so expensive.

How Many Reeds Should You Use In A Diffuser?

It is quite clear that the more reeds you use, the more oil can be soaked up and therefore the more fragrance can be released into the atmosphere. More reeds diffuse more scent and using enough reeds to fill the neck of the bottle can have the added advantage of forming a sort of stopper to stop the oils inside from evaporating too quickly.

In general, most diffusers use about 6-10 reeds though this will depend on the size of your chosen bottle. If you are aiming for a very strong scent, the more reeds the better, If you find the mixture is too overpowering, using less reeds might help to lessen the intensity and reduce its immediate impact. Less reeds will also make the perfume last a little longer as the liquid will evaporate more quickly the more reeds you use.

How Often Should I Rotate The Reeds?

You can rotate the reeds as often as you like to get the most out of your fragrance. Rotating the reeds means that you can get a stronger scent because the top of the reeds will now be more heavily saturated with perfume oil as these reeds have been sitting in the liquid for some time.

Some people rotate the reeds every day to maximise the fragrance, although you need to remember that this will cause the whole diffuser to evaporate more quickly and will use up more of the perfume. In most cases, you need to flip the reeds at least once every few days.

How Long Will Perfume Last In A Diffuser?

In general, a 100 ml reed diffuser with perfume should last around three months. If the temperature in your home is quite high or the diffuser is placed somewhere well ventilated, you might find that the perfume evaporates more quickly.

This will also be the case if you rotate the reeds very often, If you have chosen a perfume with a high concentration of top notes, you might find that the fragrance changes and if there aren’t enough base notes to carry the scent for longer, there will very soon be no smell left at all.

How Can I Make My Reed Diffuser Last Longer?

Rotating the reeds is a great way to give the scent a boost that will make it more noticeable for longer although this will help the liquid to evaporate more quickly.

Another good way to make the diffuser last longer is to keep topping up the perfume oil. When you first created the perfume oil, you might have made more than you could fit in the bottle. Any leftover can be stored in a sealed bottle or jar so you can top up the oil as often as you need to make the diffuser last as long as possible.

If you find the perfume is still evaporating too quickly, you could try moving the bottle to somewhere cooler or less draughty. You could also try replacing the reeds as they will become completely saturated over time and less able to soak up more perfume. As a general rule, all reeds will need to replaced after about six months.

Room Scent Layering

Just as you can experiment with perfume layering on your body, mixing 2 different scents can be an interesting way to create a layering effect in your home so the scent doesn’t fade into the background.

You could have different fragrances in different rooms. This way, the fragrance will be more noticeable when you move from one room to another and you can give each space a character or personality of its own.

You could also try fragrance layering by combining two or more diffusers in the same space, though you will need to make sure the room is big enough and well-ventilated as you don’t want to create a heady atmosphere.

Another way to experiment with fragrance layering in room diffusers is to add more than one perfume to the bottle at the start. Through trial and error, you might find the perfect blend to create a signature scent that is unique to your home.

Using your wearable perfume in your reed diffusers is not only a great way to use up older perfume that you no longer wear but can be an exciting way to make your home smell inviting and truly unique.

How Much Essential Oil to Add to Diffuser

If you have an ultrasonic diffuser, you may find yourself wondering how much essential oil to add to diffuser. After all, you don’t want to add too much to your diffuser and overwhelm yourself. You also don’t want to add too little and not have enough scent permeate the air.

I know it took a little trial and error on my part before I found the perfect balance, and I wanted to share my findings with you. This way, you can use this guide with your own ultrasonic diffuser. You’ll be able to enjoy your diffuser and favorite essential oils sooner, and this is great news.

Quick Navigation

Why is it Important Not to Use Too Much Essential Oil in a Diffuser?

There are several reasons why you wouldn’t want to add too much essential oil to your diffuser. First, the fragrance from the essential oils can be very overwhelming, especially in smaller spaces. Some essential oils have strong scents in the first place, and they get stronger when you add too much to your diffuser and switch it on.

This exposure to the stronger essential oil smells can actually cause a few problems for the people who breathe them in. The problems can get worse if the person has sensitivities or allergies to the oil’s fragrance itself. Some of the most common symptoms include:

  • Dizziness
  • Eye Irritation
  • Giddiness
  • Headaches or Migraines
  • Respiratory Tract Irritation
  • Nausea
  • Vomiting

What to do if You Add Too Many Drops

Once you switch your diffuser on, it won’t take too long to realize that you’ve added too many drops of essential oils. You’ll start tasting it, and you could get a headache. However, you can fix it relatively easy. You may believe that you have to leave your house until the overwhelming scent goes away and the diffuser empties itself. This isn’t the case, and it’s a good thing too because it could take up to 12 hours if you have a larger diffuser.

To help cut the scent, you want to empty the reservoir into another jar. You can split this up between two uses. Now you’re free to dilute the mixture with more water. Add the water back into your reservoir. You may want to wait a few hours to switch it on again if it’s still a strong scent.

How Many Drops of Essential Oil in Diffuser?

When it comes to any essential oil diffuser; less is always more. They’re very concentrated, and this means that they have strong scents. A good rule of thumb is to start out with a few drops and work your way up. Your goal is to get a light and lasting scent instead of a dousing.

Most ultrasonic diffusers hold 100mL of water. Ideally, most people recommend between three and five drops of essential oil for every 100mL of water. Also, your amount will depend on the size of your diffuser and where you have it in your home. You can get different size diffusers, but most of them go up by 100mL. This makes it relatively easy to adjust your essential oil amount. They start at three to give and go up to 10 to 20 drops for the larger ones.

Diffuser Size Number of Drops
100mL 3 to 5
200mL 6 to 10
300mL 9 to 12
400mL 12 to 15
500mL 15 to 20

How Many Drops of Essential Oil in a 100mL Diffuser?

We mentioned that a 100mL essential oil diffuser is the industry standard. Normally, you’d only need between three and five drops of essential oils for this size diffuser. It’s best to start on the low end and work your way up to five.

This is your guideline amount, and you can add or take away oil as needed. For example, you’d most likely use less oil for a smaller or less ventilated room. Your oil’s strength will also play a factor. Some essential oils have stronger scent profiles than others.

You want to keep your essential oil diffuser running at peak performance. To ensure this, it has to stay clean. This is especially important if you routinely use several different essential oils. The oil residue can mix together and create an unpleasant scent.

You want to make a point to take your essential oil diffuser apart and clean it after each use. Not only will this get rid of the oil residue, but it’ll clean away any hard water buildup that can negatively impact how well your diffuser works.

Diffusing on an Intermittent Cycle

Your first instinct may be to diffuse continuously. However, this isn’t good for your diffuser or yourself. If you continually run your diffuser, your nervous system acclimates to it much quicker. This means that any benefits you could get from the essential oils don’t increase. (1)

Ideally, you want to diffuse for 30 to 60 minutes before shutting it off for 30 to 60 minutes. This intermittent cycling allows you to increase the benefits that you want to get from your essential oil. It’s also recommended to breathe fresh air between cycles. (2)

Consider the Location

The number of drops of essential oil you put into your diffuser relates to the size of the room you have the diffuser running in. Although the guidelines of three to five drops of essential oils for every 100mL is still a good rule of thumb, you’ll most likely go on the heavy side for a bigger area.

If you have a larger 300mL ultrasonic diffuser, you’ll put in at about 150mL of water. This means you want 10 drops of oil. A 500mL diffuser will use 15 or 20 drops or more to spread throughout a room. Another point to consider is your ventilation. You want a very well-ventilated room for your diffuser. This will help prevent the oil scent from building up and overwhelming you. You can try to open a few windows or run fans if you don’t have good ventilation.

Using Diffuser Around Kids or Sensitive People

Can you diffuse essential oils around babies or people with sensitivities? The answer is yes, and no. You don’t want to run a diffuser around your baby, especially a baby under three months old. The oils may be too strong for your baby to handle because their organs aren’t fully developed, and they’re much smaller than we are. It’s easy to overwhelm them with essential oils.

Another situation where you want to be very careful with diffusing essential oils is around people with sensitives. If it’s sensitivity, you may have to cut back to only a drop or two of essential oils. In a 100mL diffuser, you’ll only put in a drop or two at the most instead of three to five. This allows everyone to enjoy the scents without causing irritation or sneezing.

If You Have Asthma or Allergies

Inhalation is a safe way to use essential oils, but you do want to exercise caution if you have asthma or allergies. The smell of the essential oils could set off a reaction or irritate your respiratory tract. Most people can safely diffuse lemon, lavender, fir, cedarwood, grapefruit, tangerine, and spearmint without a problem.

However, there is a popular group of essential oils that you want to exercise caution with because they’re irritants for your mucus membranes. You should consider avoiding bay, cinnamon leaf or bark, clove leaf or bud, peppermint, lemongrass, and thyme.

Quality of the Essential Oil

It’s important that you purchase your essential oils from reputable brands. This is so important because the FDA doesn’t test essential oils for safety or how well they work before they go to the consumers. Essential oils that are impure increase your chances of having a negative reaction. This is why you should always buy authentic, pure, and genuine essential oils from trusted sources.

Diffusing Essential Oils Around Pets

As a general rule, pets are more sensitive to essential oils. You want to monitor your pets when you first start diffusing new oils. If you notice that they act different, remove them from the area and stop diffusing the particular scent.

Many of us work hard to make good choices when it comes to our foods. We know this is important – and we try to avoid hormones and GMOs, and eat organic products when possible.

But, are we doing the same thing with our personal care products?

You may be surprised to learn that research indicates there could be some danger in the synthetic fragrances used in our air fresheners, shampoos, soaps, perfumes and more.

Whether you are looking for healthier alternatives to synthetic fragrances or simply want to try a new scent, essential oils can be used to create natural perfumes with a variety of aromas that will delight your senses.

The Dangers of Synthetic Perfumes

One of the biggest problems with synthetic perfumes is that their harmful chemicals can be absorbed directly through the skin and into the body.

According to the Environmental Working Group (EWG), more than 75% of products listing “fragrance” as an ingredient contain phthalates, a known carcinogen that has been banned in toys in the United States. Phthalates have been shown to disrupt hormone activity, reduce sperm count, cause reproductive malformation and have been linked to liver and breast cancers, diabetes and obesity. Reference: EWG

If you’re on a natural journey and looking to clean up your beauty routine, many health experts recommend avoiding products with “fragrance” on the label.

Natural Perfume Alternatives

The good news is that you don’t have to avoid wearing perfume. In fact, you can use essential oils to create an endless variety of delightful blends that after a pleasant and mood enhancing aroma.

Plus, as these oils are inhaled and absorbed into your body, you may experience a few other added aromatherapy benefits, too. They may help lift your mood, improve energy, relax you, and more.

We believe that wearing essential oils is a great way to enjoy a beautiful aroma through a natural perfume.

Essential oils are highly concentrated versions of the natural components in plants that possess potent therapeutic qualities used in your natural personal care products, essential oils can also offer additional wellness benefits.

8 Ways to Diffuse Essential Oils Without A Diffuser (and Why You Should)

Scented candles are a common go-to for “freshening up” a room and setting the mood with cozy or romantic lighting. But in some cases, scented candles can be hazardous to your health, releasing toxins into the air and contributing to indoor air pollution.

Although it depends on the candle, most release various types of toxic chemicals, such as benzene and toluene, both of which may affect the central nervous system. Chemicals in candle fragrances can cause damage to the lungs, brain, and central nervous system, as well as developmental difficulties, asthma attacks, and migraines.

Diffusing Essential Oils

Organic essential oils provide a safe, effective alternative to toxic scented candles. They smell incredible and enhance mind, body, and spirit. Choose based on your scent preference and/or the benefits essential oils offer, such as supporting breathing (eucalyptus), soothing an upset stomach (peppermint), or creating a relaxing environment (cedarwood).

Using an oil diffuser helps to disperse essential oil molecules into the air, giving your space a natural scent and helping you reap amazing benefits. However, using an electric, battery-operated, or candle-powered diffuser isn’t always feasible. For a more portable, quick fix of your favorite essential oil, try one of these methods:

  1. Bottle: The easiest way to enjoy the aromatic benefits of essential oil is directly from the bottle. Uncap the essential oil bottle, hold it a few inches from your nose, and move your hand back and forth over the bottle to wave the vapors toward your nose.
  2. Hands: Place a drop or two of essential oil into your palm, rub hands together, and then cup your hands over your nose and inhale deeply.
  3. Tissue: Diffusing oils on a tissue is inexpensive, requires no equipment, and can be done anywhere, anytime. Place 2-3 drops of essential oil on a tissue and keep it nearby. You can tuck it into an air vent in your car or simply hold it close to your nose and breathe in. Refresh with 1 drop every hour.
  4. Room Spray: A quick spritz into the air helps freshen a room and mask odors. Fill a spray bottle with distilled water. Add 5-6 drops of essential oils for every ounce of water to create a 1% dilution, 10-12 drops for a 2% dilution, and so on. Since essential oils vary in strength, start with less. You can always add more.
  5. Jewelry: Terracotta pendant diffusers can be worn on a necklace or bracelet. They’re great for emitting a signature scent without putting it on your skin. Simply apply a few drops of essential oil to the pendant and breathe in the molecules as the oil evaporates. Refresh with 1 drop as needed.
  6. Toilet Paper Roll: A great way to keep your bathroom smelling fresh is to put a few drops of essential oil on the cardboard tube inside a roll of toilet paper. Every time someone unrolls some toilet paper, air will flow across the essential oil and diffuse it into the air.
  7. Cotton Ball: For a quick burst of essential oils, place a few drops onto a cotton ball, and then place the cotton ball in your car vent, floor vent, or even on the blade of a fan — just be sure to turn off and unplug your fan before taping the cotton ball to the fan, and completely remove your hands from the fan before plugging it in and turning it on.
  8. Pillow Case: Drift off to sleep with the safe scent of essential oils. Just a couple of drops on the corner of your pillow case is all it takes!

25 Ways to Diffuse Essential Oils (Without a Diffuser). One Essential Community.

Qutab, Marina. (2017). Why You Need to Ditch Scented Candles and Find Non-Toxic Alternatives. One Green Planet.

By Ann Timm, Contributing Writer

Do you love essential oils, but you’re not ready to spend a whole lot of money on them yet?

I hear you. When I first started using oils a number of years back, I was really intrigued by the idea of how they worked, but not so keen to fork out $40-$100 on a diffuser to go along with the already somewhat pricey oils.

For those who can’t afford to (or don’t want to) buy a diffuser, but still want to experience their benefits, there are a whole lot of ways to do it!

Of course, EOs can always be used topically (on the skin directly), which is an effective method, but many oils are “hot” or stronger oils, require dilution, can cause irritation or side effects, and shouldn’t be used topically without a lot of care and really knowing what you’re doing.

Inhalation is an easier place to get started, because you’re a lot less likely to cause a strong reaction, but can still experience many of the same benefits.

Here are 8 ways to use essential oils without a diffuser:

1. Cotton ball

Simply put a few drops of your oil of choice, or your favorite blend of oils, onto a plain cotton ball. You can place the cotton ball into a fan vent in your car or your floorboard. The moving air will flow through the cotton ball, diffusing the scent. I’ve also put eucalyptus on a cotton ball and placed them gently into my kids ears to help with ear aches but be careful just to put a drop if you don’t want it to be topical!

2. Spray bottle

Any type of spray bottle will do. Repurpose the one under your sink or grab an inexpensive spray bottle from the local dollar store. Add a few drops of your oil to some water and use as an air freshener. Try our popular air freshener recipe, it uses vinegar to help neutralize odors while freshening with your oils at the same time.

3. Tissue method

Sprinkle oils onto a tissue, hand-towel or washcloth near where you work or sleep. One of my favorite places to sprinkle oil is on my pillow case at night. I use lavender for a calming effect. It works wonders for my children at bedtime as well. Tip – if you are afraid it will end up in your hair or on your skin just sprinkle it onto a hand towel and place it under your pillow. Sleep well…..

4. In the dryer

Dryer balls are new for me. My local county fair was selling alpaca wool dryer balls this past summer. My girls begged me to get a few. I think they just liked the alpacas and my husband was enjoying juggling with them so I decided to give them a try. They are super inexpensive and seem to last forever. I just leave mine in the dryer so that all I have to do is add a few drops to one of the balls. If you do not have dryer balls just sprinkle the oil onto a washcloth and toss it in.

5. On the stove

One quick way to aromatherapy is simply using a pot on your stove. Fill part way with water and drop a bit of your EO in. Make sure it doesn’t boil, just steaming will do the job. Add more as needed. This is sure to fill your kitchen with fragrance. I do this when my kids have cold or just to enjoy over the holidays with oils like orange and cinnamon.

6. Diffuser necklace

Terracotta pendants worn as a necklace make an affordable alternative to a diffuser. Essential oil applied to the pendant is absorbed into the clay. It will slowly diffuse into the air just under your nose to enjoy or to help a cold.

7. In the bath

Draw a warm bath, add a few drops of a relaxing oil or your favorite scent. Sink in and let the stress of the day melt away. Note that this oil will end up on your skin diluted to some degree.

8. Palm or bottle method

In a pinch, simply open the bottle, take a deep breath in, and repeat every few minutes. But if it’s an oil you feel safe to use on your skin, you can put 2-3 drops on your palm and rub them (diluted with a small amount of carrier oil, depending on what you’re using), and then cup your hands under your face and breathe in deeply.

Ever feel confused about essential oils?

I’ve been dousing my kids, their clothes and their pillows with essential oils for over a decade, but with all the different oils and their uses, it’s still daunting, even for a seasoned user like me.

I love to use lavender oil on my dryer balls to make the laundry smell fresh and on my kids’ pillows (and mine!) to help them relax at bedtime. I use eucalyptus and an inhale blend for seasonal or environmental threats and sometimes I use peppermint for a mouth rinse or DIY toothpaste.

I often wonder, though, if there’s another oil that would be better for this ailment? Or, am I using the right carrier oil? Should I put this on their skin or is it best for them to inhale it?

I have six kids and they all have different needs. Some have allergies and others are prone to every cold that comes around. One stresses easy and another has tummy troubles.

With so many issues and unanswered questions, it can be hard to know where to start.

I decided to take Essential Oils Course For Families and right away I knew I had found the place.

I value evidenced-based information from a reliable source. After all, I am using this stuff on the most important people in my life, my family, and they trust me to make good choices for them.

This course was created by Jessie Hawkins, the founder of Vintage Remedies and the Franklin Institute of Wellness. She has a master’s degree and postgraduate education in the health and wellness field. She is currently working on her doctorate in public health promotion with an emphasis on integrative family health prevention. What I love about this is that it means she is specifically trained to evaluate new and existing studies and to translate them into understandable, verifiable evidence-based information for her students.

I’ve been extremely impressed with Jessie. Not only does she have the qualified education above to share about essential oils, but her extensive education includes childbirth education, labor support, clinical herbalism, and integrative health approaches to autism and ADHD. This girl knows her stuff! I know I can trust her to help me make good decisions for my family.

When I signed up for this course, not only did I get access to her website resource library which is quite substantial, but there is access to a “study hall” for questions and current topics that is only available to her students. In addition there, is a private FB group for students to ask questions and receive encouragement.

If that wasn’t enough to get all of my questions answered, I was assigned to a personal course instructor who could guide me through the course if I needed it and help make sure I get answers my questions. She emailed right away to make sure I was able to get started.

The topics in this course cover essential oils, carrier oils, and herbs. Prevention, using oils safely with children, aromatherapy for pregnancy, birth, and babies, and aromatherapy for teens and adults, plus a ton more. With five teenagers in my house, THIS was a great find as usually the articles I read are geared more towards young children or just adults.

Here is the list of essential oils covered in the course:

  1. Ginger
  2. Lavender
  3. Clove Bud
  4. Lemon
  5. Cinnamon Bark
  6. Rosemary
  7. Clary Sage
  8. Ylang Ylang
  9. Grapefruit
  10. Tea Tree
  11. Sweet Orange

Also included are DIY tidbits on skincare, use of herbs for salves and ointments and real food recipes including drinks like “Thyme Limeade,” herbal ice cubes that look positively delicious, homemade ghee, salads and desserts.

Essential oils eliminate odors, purify the air, and help you relax. One of the most popular ways to use essential oils is in essential oil diffusers

We’ve talked about essential oils a bit here before. Mainly I’ve shared our favorite essential oil blends for each season and how to scent your home naturally with essential oils. One of the most popular ways to use essential oils is in essential oil diffusers. These amazing little devices break down the oil into tiny modules and disperse them through the air. When you inhale the oils, these molecules enter the bloodstream almost instantly. Since the integrity of the oil stays intact, you get the full therapeutic benefits from the oils.

Types of Essential Oil Diffusers

The main types of diffusers are:

Heat diffuser

There are two types of heat diffusers. One type uses a candle to produce heat and the other is electric. To use fill the small bowl with water, add a few drops of oil and then turn it on or light the candle underneath the bowl.

Evaporative diffusers

This type uses a fan to evaporate and disperse the oil. Simply place the oil on the filter or pad and turn on the fan.


This diffuser uses water and ultrasonic vibrations to disperse a fine mist containing essential oil molecules into the air. It can also double as a humidifier.


This type of diffuser is the most powerful of all and it’s perfect for large areas since it sprays a powerful mist into the air. Since it doesn’t use water there is nothing to prepare so it’s easy to use. Simply attach the bottle of oil to the diffuser and set the timer.

Reed diffusers

This is the simplest diffuser of all. Place the reeds in a vase or jar with water and essential oils. Over time they will absorb the oil and disperse the aroma into the air. Flip the reeds over occasionally to enjoy the amazing fragrance.

Tips for Getting Started with Essential Oil Diffusers

Now that you know a little about the main types of essential oil diffusers available, here are a few tips to help get you started:

  • Choose your oils carefully and always use high quality pure oils in your diffuser for the best results.
  • Some of the most popular oils used in diffusers are lavender, frankincense, ylang ylang, peppermint, eucalyptus and lemon. Keep in mind that some oils are too strong for children and should not be used in a diffuser if you have kids.
  • Essential oils are very potent so start with three or four drops. You can always add more if needed but using too much oil or using for long periods of time can cause problems such as burning eyes, nausea and headaches.
  • Diffuse the oils for approximately 30 minutes every two to three hours for the best results. There is no need to use a diffuser constantly.
  • Don’t mix the essential oils with carrier oil when diffusing. You only need carrier oils when you use essential oils topically.
  • When using a heat diffuser, don’t get the oil too hot because it will destroy the molecules making the essential oil less effective.
  • If your diffuser uses a candle, keep the oils away from the flame because they are flammable.
  • If your diffuser uses water, be sure to keep it filled when in use. Empty and wash the water container after each use and use distilled water because it won’t leave a mineral residue like tap water does.
  • Clean your diffuser regularly with distilled white vinegar and follow the manufacturer’s instructions to avoid damaging the device.

Diffusing essential oils have many benefits. Depending on which oils you use, a diffuser can eliminate odors, purify the air, help you relax and help create a peaceful environment for sleeping. They also come in a variety of shapes, styles and sizes making it easy to find one that matches your décor and budget.

There are 4 basic types of oil diffusers.

Each of these diffusers uses a different process to disperse the essential oils into the air and come with their own unique benefits, and in some cases, limitations.

  1. Ultrasonic (Ultrasonic Vibration)
  2. Heat (Heat)
  3. Evaporative (Wind/Fan)
  4. Nebulizer (Force/Atomization)

Ultrasonic Essential Oil Diffusers

What is an ultrasonic diffuser for essential oils?

Ultrasonic diffusers dispense healing essential oils into the air as negative ions. These diffusers get their name from the ultrasonic vibrations used to break down the essential oils into microparticles, allowing the oil to be dispersed as a very fine mist, mixed with steam, into the air. The process does not create a lot of noise, allowing the diffuser to run extremely quietly – ideal for relaxing, sleeping and working.

Does an ultrasonic diffuser use heat?

The ultrasonic diffuser process is adiabatic, meaning that the oil changes states without the use of heat. Because no heat is used in process, the integrity of the oil is fully preserved upon dispersal.

Can an ultrasonic diffuser double as a humidifier?

Yes, an ultrasonic diffuser uses water as part of the dispersal processes, adding the benefit of humidifying the room. Added water is sometimes criticized as it dilutes the potency of the oils, but for those who do not prefer overwhelming smells and for their oils to last longer, mixing them with water for dispersal can be seen as a good thing.

Heat Essential Oil Diffusers

What is a heat diffuser for essential oils?

A heat diffuser heats the essential oils until they evaporate into the air. Thicker oils, like Sandalwood, can be well-dispersed into a room when using a heat diffuser. Heat diffusers come in many types, including electric heat diffusers, candle heat diffusers and lamp ring. All models of heat diffusers use a tray where the oil is held next to the heat source so that it will heat and evaporate.

What are the disadvantages of heat diffusers?

While heat diffusers are an economical option that do a good job of their basic function – dispersing the essential oil – the use of heat changes the essential oils at the chemical level – changing and in many cases, limiting, the health benefits of the oils.

Evaporative Essential Oil Diffusers

What is a evaporative diffuser and how does it differ from a heat diffuser?

While heat diffusers also distribute the oils via evaporation, evaporative diffusers use a fan to generate a wind vs. heat, to cause the oil to evaporate into the air. The oil in an evaporative diffuser is held in an absorbent material – usually a pad or a wick – so that the wind causes the oil to evaporate in a controlled fashion.

Nebulizer Essential Oil Diffusers

What is a nebulizer for essential oils?

A nebulizer is sometimes said to release the purest form of the essential oils, for the best in aromatherapy. This is because of the concentration that a nebulizer produces by breaking down the oils into atoms by force, much like a perfume bottle.

How are nebulizers used for aromatherapy?

Unlike other diffusers, Nebulizers require no heat and no water. They deliver a concentrated and pure stream of essential oil dispersion, though you will likely need to place it on a timer in order to prevent the oil from quickly running out. This concentration and purity makes nebulizers a great option for aromatherapy.

Why should I use a diffuser?

Aside from being a great smelling alternative to candles or wax melts, essential oil diffusers can help you to relax with calming lavender, lift your spirits with a fun vanilla scent, remove airborne pathogens with tea tree or thyme, open your airways with cooling eucalyptus and more. The health benefits of using a diffuser that contains water also include doubling as a humidifier to help your dried out airways.

About the NOW brand.

NOW is well known for its affordable line of natural products. Ultrasonic diffusers, like NOW brand’s ultrasonic wood grain oil diffuser, have the benefit of breaking down the oils into particles tiny enough to be easily breathed in and absorbed by the lungs. Each type of essential oil has its own health benefits!

How Does a Nebulizing Diffuser Work

The Nebulizing Diffuser® by Organic Aromas® offers the most effective dispersal and the most complete rendering of both the natural scent and the therapeutic properties of 100% pure, organic essential oils on the market. This unique device is entirely safe, extremely quiet, makes no mess, requires no heat and does not use any water.

Both beautiful and powerful, this one of a kind aromatherapy instrument is perfect for individuals, professionals and businesses alike. Using nothing but pressurized air and a combination of delicately hand-blown pyrex glass paired with an elegant hand-crafted plantation hardwood base, this nebulizing essential oil diffuser is the best choice for those who wish to experience the fantastic aroma and full health value of only pure essential oil.

The Best Essential Oil Diffuser for Aromatherapy

Unlike the wide variety of heated units and multitude of plastic, humidifier diffusers that litter the market today, ours works without the need to heat up the oils and without the need to add water to the diffuser. The Organic Aromas Nebulizing Aromatherapy diffuser works by using what is known as the Bernoulli principle, a theorem of fluid dynamics that provides the best results when diffusing pure essential oil. Here are the basics of the process.

  • 01When an air current is forced through a small tube, the velocity is increased while the pressure at the exit point is reduced.
  • 02That difference in pressure creates a kind of suction that causes the essential oils within a separate glass tube to rise upwards.
  • 03As the essential oil rises, a stream of pressurized air hits the essential oil and causes it to atomize into micro particles that fill the glass reservoir.
  • 04Once in the glass reservoir, those tiny particles rise up and are emitted out of the glass cap in a (water-less) mist that is released into the local environment.
  • 05The remaining particles of essential oil return to the bottom of the diffuser creating a cycle that will repeat until the oil has been used up completely.

With this method the essential oil is not diluted by water so it is much more powerful. Also, no heat is required so the chemical structure of the essential oil is not altered. In addition, because the diffuser uses glass the essential oil never comes into contact with plastic. The particles of essential oil reach you in their natural state and provide you with all of their original therapeutic benefits.

The Differences Between The Nebulizing Essential Oil Diffuser And Others

Compared to some of the other types of diffusers out there today, our Nebulizing Essential Oil Diffuser simply makes more sense. Not only is it beautiful and effective, it is clean, safe and quiet! Consider some of the other options available:

Ultrasonic diffusers use water to carry the essential oils into the air. Not only can the oils eventually damage the plastic diffuser, but the water means that your home is filled with added humidity! Also, the scent emitted is weaker because it is diluted by water. Oil lamps are messy and dangerous, working almost like a kerosene lamp that burns flammable chemicals and completely changes their molecular makeup. Sure, it smells nice, but that’s about it. And it’s far more dangerous. Candle diffusers work similarly, and are the more common option used today. But they still use heat, which means that your essential oils are diminished in quality thanks to the burning that causes changes in the oil on a molecular level.

What are Essential Oil Diffusers and what do they do?

Essential oil diffusers are considered as the harbingers of the essence of beauty and health. The history of essential oil diffusers can be traced back with the history of aromatherapy, an alternative treatment which uses traditional ways of healing ailments by the use of herbs, inhaled or smoked.

The use of essential oils themselves goes back in time of the ancient civilizations of China, Egypt and Rome. Various essential oils have been used medicinally at various periods in history. If you’d like to read more about essential oils and what they are, please head over to “What are essential oils?”.

Simply put, essential oil diffusers enhance an environment by spreading the fragrance of herbal and essential oils throughout the air. This form of aerial diffusion is one form of aromatherapeutic application. There are different types of diffusers – some of which use heat, others don’t – all of which have their own use and application.

In general though, essential oil diffusers serve both the aesthetic and therapeutic purposes of essential oils treatment. Oil diffusers are produced with as much science as well as art put into them, and the tremendous health and wellness benefits are indeed great.

5 benefits of using essential oil diffusers are:

  • Purification and disinfection of the air against all forms of virus, pathogens and bacteria
  • Sets the mood and impact for aromatherapy
  • A focus of energy and concentration of positive health aura
  • Tangible reduction of stress and anxiety
  • Spreading the sweet fragrance inside and outside the home

How do Essential Oil Diffusers Work?

Edens Garden Ceramic Essential Oil Diffuser: Stylish AND Functional

The key as to how essential oil diffusers work, is the term permeation; “to pass into or through every part of”. When you use an essential oil diffuser, all of the little particles get distributed throughout the air, filling your room. While essential oil diffusers may also work using heat and electricity, permeation is widely regarded as the most natural way to diffuse oil. What is important is that essential oil is used as the prime ingredient of aromatherapy. Researches have shown that the scent of essential oils enter the brain to stimulate it and create a high sense of wellness and physical as well as psychological health.

The 4 Major Types of Essential Oil Diffusers

Essential oil diffusers have four main classifications, the nebulizing diffusers, the humidifying or ultrasonic oil diffusers, the evaporative diffusers and the heat diffusers.

  • Nebulizing diffusers work similar to your basic perfume atomizers. Often recognized as the best form of oil diffuser, nebulizing diffusers place the essential oil into the space of the environment in the form of droplets. It is highly recommended, of course, that essential oil diffusers must be used with timers which will automatically turn them off and on so as not to waste unwanted spread of the essential oil’s healthy fragrance.
  • The ultrasonic diffusers are oil diffusers which use electric current to cause a disk instrument to emit a vibration which will cause the spread of essential oil microparticles into the air. This type of oil diffuser creates a mist that is very suitable for an aromatherapeutic environment because they are a cold mist diffuser. No heat is applied to the oil, keeping esssential oil’s healing properties intact. It is probably the most popular type of essential oil diffuser today. If nobody says differently, you probably have an ultrasonic diffuser.
  • Evaporative oil diffusers are basically wind-blown diffusion of the essential oils. This, of course, is a highly-controlled process. There is a fractioning of the essential oils which may cause the diminishing of the therapeutic properties of the essential oils. Aromatherapy cannot be maximized sufficiently with the use of evaporative oil diffusers.
  • It is not recommended to use a candle burner for aromatherapy. Essential oil properties are altered significantly when heat is applied

    Heat diffusers are units such as candle burners (shown on the right). They cause the essential oils to evaporate quickly and may not be able to maximize the potential of the essential oils being used for aromatherapy. However, this type of heat diffusers makes it a little bit more economical as well as more silent to use essential oils, compared to essential oil diffusers using electric charge, such as the ultrasonic devices.

One important note about essential oil diffusers is that, in general, they are exceedingly better than the traditional use of candles for essential oil diffusion. It is so because candles tend to drown the fragrance of essential oils with their own wick-based scent. Thus, it will be defeating the spread of the scent of health and beauty benefits of essential oils.

Comparisons of Essential Oil Diffusers by Type

This diffuser’s colors are bright and beautiful so it works perfect as a night light.

Among the three types of nebulizing diffusers – Economy, Well & Jet and the Advanced – the economy oil diffuser has the lowest air pump power of 2.13 psi.

Nebulizing diffusers, however, have more oil capacity than the two ultrasonic oil diffuser types – Classic ultrasonic diffuser and the Whisper Misting diffuser.

Evaporative essential oil diffusers can be categorized as Fan-user, battery operated, and personal aromatherapy use while the heat oil diffusers can be classified as Autoscenter and Scent Balls.

Types of aromatherapy diffusers are:

  • Clay pot oil diffusers – have oil that permeate the container and diffuses the aroma in the air.
  • Electric oil warmers – similar to oil diffusers called the tea light. Tea light oil diffusers are mostly made by ceramic or ceramic glass.
  • Fan diffusers – used differently because a fan is used to blow and regulate the spread of essential oil mist in the room.

A Selection of Essential Oil Diffuser Brands

Lowe’s – ultrasonic essential oil diffuser which is of the silent-type and very economical. It’s easy to clean but it is rarely on sale or bargain counters.

Well & Jet – nebulizing essential oil diffuser which has high aromatherapeutic tendencies but is a bit noisy. However, it has a good control mechanism for the flow of the scent as well as the ease of combining oils in its nebulizing nodes. The downside of Well & Jet oil diffusers is they have unaesthetic tubes and user will find difficulty in changing essential oils.

Lotus – ultrasonic essential oil diffuser which is nearly quiet and so easy to wipe clean. It has an automatic shut-off system, timer and is aesthetically alluring.

In order to understand essential oil diffusers better, we also need to understand how they work and the benefits we can derive from them. Whether for the beauty or for the wellness benefits, whether nebulizing or ultrasonic essential oil diffusers, they are truly here to stay and spread the wonderful fragrance of aromatherapeutic essence.

In Summary

An essential oil diffuser is simple to use and can be put in the bedroom, living room or in any living environment where you could relax. These diffusers offer many different health benefits in an incredibly low price. You can also locate brand new and slightly used diffusers in internet marketplaces.

Essential oils could be toxic if taken orally and shouldn’t be swallowed. They are very potent and they must be diluted in a lotion or carrier oil before you can safely use them on the skin. Diffusers offer a fantastic middle ground, as only water is required to mix in with the essential oils.

Essential oils are commonly utilized in aromatherapy applications. In addition, they are widely used for beauty and body treatments. They are not perfumes. They are part of the Alternative Medicine category but are becoming more and more relevant in Conventional Medicine as scientists are realizing the importance of these very basic substances because of their wide variety of constituents. There are a number of essential oils readily available on the market. Please see the following recommended brands:

  • Plant Therapy Essential Oils
  • Edens Garden Essential Oils
  • Rocky Mountain Essential Oils

Essential oils have been shown in studies to have very few negative side effects or risks when they are used as directed. But given how popular essential oils have become in recent years, and how many different brands of oils are now available, it’s not surprising that there’s some growing concerns regarding essential oil safety.

Are essential oils bad for your health? After reading the information below, I believe that you’ll agree that no, essential oils are not generally dangerous. Overall, there’s good evidence that essential oils are both safe and can be a powerful, healing tool in natural medicine.

That being said, there are different methods of application that are most appropriate for each essential oil, so it’s important to do your research and buy high-quality oils in order to use these products safely. Essential oils may be applied on the skin (dermal/topical application), inhaled, diffused or taken internally, but it’s not always safe to use every oil in all of these ways. Some precautions are necessary, and certain oils should NOT be used topically, internally or by people with certain sensitivities.

Are Essential Oils Safe?

A key point to understand about essential oils is that they are very concentrated, meaning you only need to use a very small amount to experience results. Essential oils must be used with care and labels must be read carefully so that guidelines are always closely followed.

Here are some of the most frequently asked questions regarding essential oil safety:

Should essential oils be used externally or only topically on skin?

Depending on the specific oil, they can be used in both topically or internally. When applying oil to your skin, it’s usually best to dilute about 2 to 3 drops of pure oil with a vegetable oil that serves as a “carrier oil.” Mix a small amount of the essential oil with equal parts of coconut oil or jojoba oil and then apply to your skin over the affected area that you’re treating. Some of the best locations on the body to use essential oils include on your neck, temples, wrists, over your abdomen, chest and the soles of your feet. Essential oils should never be applied to the eyes or ear canals.

Are essential oils safe to inhale?

Yes, most essential oils are safe to inhale or diffuse. You can diffuse about 5 drops in an oil burner of diffuser, or inhale the oil directly from the bottle for several seconds. Is it bad to inhale essential oils if you’re already sick? Inhaling certain essential oil vapors can actually help to improve recovery if you’re congested, dealing with a cold or if you have seasonal allergies. (1)

For example, rosemary, peppermint and eucalyptus oil can all help you breath more easily and manage symptoms of respiratory conditions. You can also add 10 drops of oil to boiling water, put a towel over your head and breathe in the aroma for 5 minutes.

Are essential oils safe when used internally and ingested?

This depends on the specific oil. Certain essential oils have been approved as ingredients in food and are classified as GRAS (generally recognized as safe) by the U.S. Food and Drug Administration. (2) Is it safe to drink essential oils? You can use very small amounts of certain essential oils in water or tea, such as lemon or ginger oil, but in general you should use precaution when taking essential oils internally (more tips on this below).

Are essential oils safe during pregnancy?

Infants, toddlers, young children and pregnant women are all are more sensitive to the effects of essential oils. It’s necessary for pregnant women to avoid using some essential oils all together because the oils can have stimulating effects on the uterus, pose risks to the fetus, affect blood pressure, or simply because not enough research has been conducted to show that certain oils are definitely safe. Due to increased sensitivity, some oils will also need to be avoided by children, women who are breastfeeding women, and the elderly. It’s important to read labels carefully before using any oil if you’re pregnant, breastfeeding or giving oils to your children.

What essential oils are good for you and safe if you are pregnant? Some that you can safely use include: lavender, bergamot, frankincense, geranium (safe after first trimester), ginger, grapefruit, juniper, lemon, sandalwood, orange, and ylang ylang. Diffusing oils aromatically is a safe way to use essential during pregnancy because it doesn’t have as strong effects as using the oil on your skin or internally. (3)

Essential oils that should NOT be used during pregnancy include:

  • Basil
  • Birch
  • Black pepper
  • Cedarwood
  • Cardamom
  • Cassia
  • Cinnamon
  • Citronella
  • Clary sage
  • Clove
  • Cumin
  • Cypress
  • Eucalyptus
  • Fennel
  • Geranium (not considered safe during first trimester)
  • Hyssop
  • Jasmine

Are Essential Oil Diffusers Safe?

Given how popular essential oil diffusers have become, you’re probably wondering about the safest way to use one. Here’s what you need to know about essential oil diffuser safety:

  • Essential oil diffusers are used to vaporize oils, releasing small amounts into the air. The same safety concerns regarding inhaling essential oils also apply to using oils in a diffuser.
  • Overall inhalation is considered a very safe method of using oils that poses a low level of risk. It is very unlikely that the concentration of any essential oil will rise to dangerous levels due to vaporization.
  • Do not diffuse oils around newborns, babies, young children, pregnant or nursing women, or pets unless you are sure they are safe.
  • If you have allergies, asthma or a similar condition you may find that diffusing essential oils, which have strong fragrances, may trigger respiratory a reaction. Stop inhaling or diffusing essential oils if this is the case. Oils that can be less irritating when inhaled include peppermint, lavender, tea tree, eucalyptus and chamomile. (4)
  • Use a diffuser for about 30–45 minutes at a time for the most effectiveness. Don’t leave your diffuser plugged in overnight. Fill up the diffuser with a appropriate amount of water and read the directions carefully. You may want to purchase a diffuser that has an automatic stopper after about 20–30 minutes of use, which means it will turn off on its own if you forget.
  • Keep all essential oils away from flames (candles, gas, etc.) as they can be highly flammable.
  • Make sure your home/room has good ventilation. Open up windows if the fragrance becomes too intense.
  • Don’t add carrier oils to your diffuser, which might cause it to break. Periodically clean your diffuser with soap and warm water to help it to work effectively and to prevent mold or bacteria from accumulating.
  • Do not use essential oils in a humidifier, since these are not made for essential oil use like diffusers are.
  • Use caution when diffusing essential oils that might irritate mucous membranes. These include clove, cinnamon bark, lemongrass, and thyme oils. (5)
  • Start slowly when it comes to diffusing oils in your home so you can test your reaction. If you have any concerns about specific oils worsening symptoms you’re experiencing, then ask your healthcare provider about their opinion.

Best Ways to Use Essential Oils

Essential Oil Safety Tips for Your Skin: (6)

  • Always perform a small patch test to make sure you are not allergic to an oil before using it on a larger section of your skin, or taking it internally. Stop use immediately if irritation occurs.
  • Avoid application of known dermal irritant essential oils or allergens. This is especially important if you have any type of inflammatory or allergic skin condition such as eczema or rosacea.
  • Use caution when using essential oils that are more likely to be dermal irritants or to increase sensitivity to the sun (photosensitivity), which may lead to sunburns. These include: cinnamon bark, clove, citronella, cumin, lemongrass, lemon, oregano, bergamot and thyme. (7) For oils that can increase photosensitivity, do not apply the oil within the 12 hours before spending time directly in the sun.
  • If you have sensitive skin, avoid undiluted application. Dilute oils with vegetable oil or another carrier before applying to the skin.
  • Do not use essential oils excessively on your skin because this can cause increased dryness due to their lipophilic (fat-liking) nature.
  • Avoid application on open or damaged skin, wounds, burns or infected scrapes. Damaged or inflamed skin is often more penetrable and may be more sensitive to dermal reactions.
  • Certain essential oils rich in aldehydes (such as cinnamon) and phenols (such as clove and oregano) may cause skin reactions so they should always be diluted prior to skin application. Oils that may be more easily tolerated by people with skin sensitivity include marjoram, frankincence, German chamomile, myrrh, thyme and lavender. (8)
  • Essential oils should never be applied to the eyes or ear canals. If any essential oils get into the eye, place a few drops of a carrier oil in the eye and blink until the oil clears out. Wash your hands after using essential oils to avoid spreading them into your eyes.
  • If you’re experiencing signs of dermal irritation, apply a small amount of vegetable oil or cream to the area affected and discontinue use of all essential oils for at least several days.

Safety Tips When Using Essential Oils Internally:

  • Read labels carefully to make sure the oil is appropriate to use internally. Check the warnings for each oil before ingesting, and only consume essential oils that are Certified USDA Organic and labeled as dietary supplements.
  • Use only very small amounts of oils internally, about 1–2 drops at a time, up to 2–3 times daily.
  • Only use 100 percent pure oils, since using adulterated essential oils increases the likelihood of an adverse response.
  • Never use an oil internally that you are allergic too.
  • If you experience any mouth or throat irritation, dilute the oil in liquid or food (honey, applesauce, etc.) before swallowing. It’s also best to take essential oils with food rather than on an empty stomach.
  • If you’re currently taking prescription or over the-counter medications, whether taken by mouth or used on your skin, keep in mind that using essential oils at the same time can increase a drug’s side effects.
  • Always ask your doctor if you have any safety concerns regarding medication interactions. People taking heart medications, such as blood thinners, should avoid using clary sage, cypress, eucalyptus, ginger, rosemary, sage and thyme oils.
  • If you’re dealing with any type of hormonal issue, keep in mind that lavender, tea tree, chamomile, sandalwood and clary sage may alter hormone levels.
  • Keep an eye out for any signs or symptoms of a negative reaction. What are some potential essential oils side effects, or essential oil overdose symptoms? This can include eye or throat irritation, rash, hives, vomiting, nausea or dizziness.
  • If a child appears to have ingested large amounts of essential oil, contact the nearest poison control unit right away for emergency help.

Are There Any Unsafe Essential Oils?

Yes. The International Fragrance Association has banned certain essential oils because they have been found to be toxic when ingested or applied topically. (9) These banned oils that are deemed unsafe include: cade oil crude, costus root, elecampane, fig leaf absolute, horseradish, nightshade, pennyroyal, rue, sassafras, savin, southernwood, stinging nettle, stryax gum, tea absolute, wormseed and wormwood.

Final Thoughts on Essential Oil Safety

  • Essential oils are generally safe, but can be irritating or cause problems when used in the wrong ways.
  • To practice essential oil safety it’s important to use oils in the appropriate way. Essential oils may be applied on the skin (dermal/topical application), inhaled, diffused or taken internally, but the best application depends on the specific oil.
  • Certain essential oils should not be used by pregnant or nursing women, people with sensitive skin, infants, children or the elderly. Some oils may increase sensitivity to sunlight and cause irritation to the mucous membranes, so caution should be taken.
  • It’s possible for essential oils to interact with medications or over-the-counter drugs. Always ask your doctor if you have any safety concerns regarding medication interactions.

As someone who turns on multiple diffusers at once to create a hazy cocktail of soothing scent, the idea that one could diffuse too much is a bit confounding to me. After all, essential oils have been billed as wizards of the wellness world, working their magic everywhere from your complexion to your kitchen sink.

So when Jean Liao, certified aromatherapy practitioner at Way of Will mentioned to me (in passing nonetheless!) that you shouldn’t leave your diffuser on for more than an hour, I was shook. Sure, “too much of a good thing” and all, but it turns out, that when essential oils aren’t handled properly, they could potentially pose a health risk.

For starters, you should very rarely apply the oils directly to your skin because when the highly concentrated plant extracts come into contact with the dermis, they can cause irritation. And when you leave your diffuser blasting all day and all night, you could cause an over-exposure. “The common misconception is that essential oils are natural so we can use as much as we want,” Liao says. “However, we see many examples of people using it improperly which causes skin burns, irritation, or sensitization.”

“We see many examples of people using it improperly which causes skin burns, irritation, or sensitization,” says Jean Liao.

In fact you shouldn’t really be blasting it for hours straight at all. His recommendation is to turn your diffuser on between one and three times a day for up to 30 minutes at the maximum. According to him, overexposure and the act of inhaling essential oils can lead to headaches. And one study out of Taiwan found that while exposure to essential oils for between 15 minutes to an hour, led to relaxation in the 100 spa workers observed, exposure that lasted upwards of an hour, resulted in an uptick in blood pressure and heart rate.

So all of that to say, before incorporating essential oil diffusers into your home wellness routine, Liao suggests conducting a skin-patch test (to make sure the EO in question doesn’t cause a skin reaction) and also avoiding any that do. Once you’ve done that, you can go *ham* on the diffuser situation—for up to an hour, that is.

Essential Oil Diffuser Safety Tips

Essential oils can help to improve our mood, can help support our respiratory health, can help to reduce airborne germs and can help to reduce unpleasant odors. However, it’s important to diffuse essential oils sensibly and not overdo it. Start learning how to diffuse safely by exploring the following tips:

  • Before diffusing any essential oil, be sure to familiarize yourself with general essential oil safety principles and research/review the safety precautions associated with each essential oil that you use. You can start doing that by exploring AromaWeb’s Essential Oil Directory featuring over 130 essential oil profiles and reading the safety information that they contain.
  • Essential oils are highly concentrated. They should not be continuously diffused. Be sure you are diffusing in a well ventilated space.
  • Refer to the instructions that came with your particular type of diffuser. Do not exceed to amount of essential oil recommended for your particular diffuser.
  • Do not diffuse more essential oil than is necessary. Essential oils should not be diffused in significant concentration. Less is more with essential oils.
  • Olfactory fatigue is a phenomenon where you are no longer able to easily perceive an aroma, even if the aromatic molecules are still present. Even if you no longer can smell an essential oil or blend as it is being diffused, the essential oil still likely being inhaled into your lungs.
  • If diffusing around cats and other pets, be sure they aren’t confined strictly to the room in which you are diffusing. Allow them to leave the area if they need to.

Robert Tisserand, author of Essential Oil Safety and the Tisserand Institute advise the following:

“It is not advisable to directly and intensively inhale essential oils for longer than 15-20 minutes, such as with steam inhalation. However, this does not apply to ambient inhalation from essential oils vaporized into the air. If you are diffusing essential oils, it makes more sense to do this intermittently than constantly, all day long. Ideally, diffuse essential oils for 30-60 minutes on, then 30-60 minutes off. This is not only safer, but it’s also more effective as both our bodies and our nervous system habituate to essential oils after this period of time. Whenever you are using or diffusing essential oils, some air exchange (fresh air) is advisable.”

Diffusing in Classrooms and Public Places

Diffusing in classrooms, offices and public places can be a potentially risky and unsafe practice because some essential oils have the potential to exacerbate particular medical conditions. Everyone is different, and diffusing in a classroom or public space can risk the wellbeing of those who have conditions in which particular essential oils are contraindicated.

Instead, consider using a Personal Essential Oil Inhaler as an alternative.
