How Do Essential Oils Diffusers Work?

What Does An Oil Diffuser Do

When it comes to diffusers they are famous for aromatherapy. However, there are 4 types of diffusers and they all work different.

Types of Diffuser What it does
Ultrasonic (Ultrasonic Vibration) Creates Ultrasonic sound waves
Heat (Heat)Uses heat and gradually evaporates into the air
Evaporative (Wind/Fan)Uses a small fan to blow oil
Nebulizer (Force/Atomization)Blows crossed a series of tubes

Below let’s break down the 4 different types of essential oil diffusers into more details.

Essential Oil Diffuser Types

1. Ultrasonic (Ultrasonic Vibration)

Anyone who owns an ultrasonic diffuser will tell you that they run extremely quiet.

Not to mention it is one of the most popular types of essential oil diffusers. 

In fact, the name comes from the ultrasonic vibrations that it gives out. 

Here’s how:

The small disks underneath the water create ultrasonic sound waves. And then the vibrations gently break up the essential oils.For the most part, the water with the oil is discharged and misted. 

Best of all this type of diffuser can double as a humidifier. This because it uses water as part of the dispersal process.Another good thing about it is that it uses no heat.

2. Heat (Candle Diffuser)

Obviously, this type of diffuser uses heat. But the way it works is the essential oils are gradually evaporated into the air creating the aroma.

Not all heat diffusers are the same. But some use higher levels of heat.For this reason, the heat will change the properties of essential oils. 

What does that mean for you?

This means fewer benefits for you. The best heat diffusers will use low heat. Therefore won’t change the composition of the essential oil.

As a result, you will receive more benefits from the aroma of the essential oils.

3. Evaporative (Wind/Fan)

This type of diffuser uses a small fan that blows air past the oil. When the essential oil evaporates it is released into the air. 

4. Nebulizer (Force/Atomization)

You’re in a pleasant surprise. Nebulizers do not need water or heat.And is considered to be the most powerful out of all the different types.

Best of all most models cover up to 1000 square feet.

Here is how it works:

The small air pump blows the air across a series of tubes. As a result, it creates a powerful vacuum. And then the essential oils are pulled from the bottom of the tube to top.

Last but not least the essential oils are then sprayed from the top. The essential oils that are released are in their purest form. Which is wonderful because you get 100% of the benefits.

You can find essential oils almost everywhere. From the local store to about anywhere you go. There are tons of essential oil brands. And they are not all the same.

Just because you see something on the store shelve doesn’t mean it is good quality. Make sure it is a brand that you can trust. And it is high quality all-natural and organic if possible. 

However, beware that some companies use 1 drop of essential oil and leave the rest of the bottle carrier oil.And they label it as an organic essential oil. Because everything is organic.

This is an easy way to cheat you out of money.Make sure it is tested for the exact chemical profile of 100% essential oil and nothing else. 

Is it OK to use a diffuser everyday ?

When you first get a diffuser you probably want to use it all day long.

For example:
Run your diffuser for a couple of hours then you can turn it back off.

This will give time so that your body can process the essential oils. And it will give your body a chance to rest.Overall essential oils are completely saved when used correctly.


An important thing to remember is that ultrasonic diffuser and Nebulizer diffusers are the best on the market.
