Different Types Of Essential Oil Diffusers

Essential oils have been used for centuries. Right now, however, they are enjoying a resurgence as more and more people use essential oils for aromatherapy. Essential oils are more than just sweet-smelling oils that make your home fragrant – they have also shown certain medicinal effects that help in combating moodiness, reducing stress, purifying air, and improving focus and mental clarity. Essential oils are usually poured in small amounts onto diffusers to effectively distribute the vapor or mist into the air. Oil diffusers are fairly easy to use but to truly optimize their benefits, you have to know how each type works so you can choose the best one for your needs.

How Do Essential Oil Diffusers Work?

In general, essential oil diffusers are designed to disperse tiny particles of oils into the air. This is considered one of the best ways to use oils for aromatherapy because the particles can be released within a covered area, such as a room. There are different types of essential oil diffusers that disperse the vapor form of essential oils. The method of dispersion will depend on which type of diffuser you choose. Here’s a basic look at each diffuser type.


A heat-type diffuser uses heat to cause the essential oil to evaporate. This type of essential oil diffuser uses a heat source, such as a lamp, a candle, or an electric bulb. The heat source is typically located under the bowl or tray on which the oil is poured.

Pros: Economical and easy to use, can disperse pure essential oil molecules effectively.
Cons: The use of heat could change the chemical properties of the oil.


Evaporative type diffusers utilize a fan to cause the oil to evaporate. To expedite the process, the oil is often poured onto a wick, pad, or any other absorbent material so it can evaporate more easily.

Pros: Evaporative diffusers can release a controlled amount of essential oil into the air.
Cons: Dispersion may be slow and may not be as effective in larger spaces.


The nebulizer type uses force to break down the oil to turn it into very fine particles before it is dispersed into the air. Nebulizers deliver pure, concentrated essential oil particles because they do not require water or heat to work. The scent of essential oils is typically stronger when delivered through nebulizers.

Pros: Delivers a concentrated dose of the essential oils; quiet operation; may be used overnight with a timer.
Cons: The dose may be too potent or strong-smelling for some individuals; will not work without a source of power; a bit more expensive than other types of essential oil diffusers.


An ultrasonic diffuser utilizes ultrasonic vibrations to break down the oil into smaller particles. These particles are light enough to be dispersed with steam and released into the air.

Pros: Can disperse essential oil effectively; may be used as a humidifier; more affordable than nebulizing diffusers.
Cons: Requires water to use; may not deliver as strong a dose as nebulizers; requires a source of power to use.
