Essential Oil Diffuser Comparison: Which Type of Diffuser is Best?

Recently, I’ve had several people ask me about essential oils diffusers… why they should be used, and which diffusers are best. So, I’m writing this blog post as a reference for anyone who wants to see a comparison of diffusers.

Keep in mind, in this blog post, we are only discussing 2 types of diffusers because they are the 2 best options (in my opinion). You can find other types of diffusers out there, such as evaporative diffusers and heat diffusers, but both of those methods affect the compounds within the essential oils and can cause the essential oils to evaporate more quickly. When essential oils evaporate too quickly, it can affect the compounds within the oil, because the oils may actually be fractionated before they are released into the air.

So, instead of wasting your time by having you read information about diffusers that I wouldn’t personally suggest, I am simply highlighting the 2 types of diffusers that I like to use:

Ultrasonic Diffusers (AKA Humidifying Diffusers)

An ultrasonic diffuser creates a fine mist with the essential oil, by applying electronic frequencies to the oil. Typically, the diffuser will use water which has an electronic piece of metal in the water to send frequencies

thru the liquid. When you add essential oils to water, the oils stay on top of the water (remember that oils and water don’t mix together), and the fast vibrations from the electronic frequencies cause tiny particles of the essential oils to break away and go into the air in a fine mist.

The good thing about ultrasonic diffusers is the fact that they use a small amount of essential oil (so you don’t go through the oils too quickly), and no heat is used in the process. The reason heat should be avoided is because the heat can affect the chemical make-up of the essential oil, so it is best to avoid heat whenever possible.

Becki’s opinion: To be honest, an ultrasonic diffuser was the first type of diffuser that I purchased, and I really liked it in the beginning. But, I figured out that they don’t seem to last as long as other diffusers, I personally experienced 2 different ultrasonic diffusers that stopped working after awhile because the metal piece stopped sending the vibrations through the water. That was my personal opinion, I know other people who have used these diffusers for a long time with no problem… maybe I just had bad luck with them? LOL! :)

Nebulizing Diffusers (Becki Favorite!)

A diffuser with a nebulizing feature actually uses a jet of air to blow the essential oil into the air in the form of a very light mist. One of the reasons I like a nebulizing diffuser is because it is a fast and effective way to diffuse the oils into the air, it literally takes just a few seconds before you can smell the oils being diffused.

The great thing about nebulizing diffusers is it is an effective way to keep the oil in the “truest” form, allowing full benefits of the essential oil. A nebulizing diffuser does not use heat, and it doesn’t cause the essential oil to evaporate too quickly. When a nebulizing diffuser is used, it doesn’t fractionate the oil before releasing it into the air… the essential oil is in it’s whole form when it is in the air (which is the most effective way to use therapeutic essential oils).

The drawback to using a nebulizing diffuser is the fact that is goes thru the essential oils more quickly, because it is so effective at getting those oils into the air. Because a nebulizing diffuser is my personal favorite, I have found 3 ways to minimize costs when I am running a diffuser:

1. Use a nebulizing diffuser that has a timer feature. The model that I have allows you to control the output of the oil, and you can also set a time for the number of minutes that it should run, and the number of minutes it should turn off. So, you can set the diffuser to specific time frames, and it will turn on-and-off automatically throughout the day.

For example, I often turn on my diffuser at a lower output setting, and set the timer to turn on for 5 minutes and off for 10 or 15 minutes. This setting means that my diffuser will turn on about 3 – 4 times per hour, fill the room with uplifting essential oils, and then turn off.

This timed use of the diffuser allows your body to to process the oils that have been breathed, before more oils are put into the air again.

2. Turn down the output of the diffuser. It is not necessary to have the mist turned as high as it can go… remember that a little bit of essential oil goes a loooooong way!

3. Use a cheaper essential oil as the base oil in the diffuser. When I say cheaper, I don’t mean that you should sacrifice quality of the essential oil brand… but instead choose high quality essential oils that are less expensive.

I use a lot of citrus essential oils in my diffuser because they are inexpensive, and the fresh scent is wonderful in the air. For example, a bottle of citrus essential oil costs between $10 – $15, which is much cheaper than some of the more expensive oils that can run as much as $50+ per bottle. If you want to use an expensive oil in the diffuser, consider adding a few drops of the expensive oil to a cheaper oil to create a blend.

One of my favorite diffuser blends of essential oils is orange and peppermint. I love to use a base of Wild Orange, and add a few drops of peppermint. It is a great pick-me-up, and it is a happy blend. I love it!

With love,

I have enjoyed reading several of your articles and video teachings and have to say I have learned more from you than any other website I have come across. I always wondered why the price difference and the benefit factors. Great job clarifying!!!
I would love to see pictures of diffusers and where to purchase them!
