6 Types of Diffusers

Resize8There are 6 different ways to diffuse essential oils. Here are the 5 types: candles, heat diffusers, simple ceramic diffusers, evaporating diffusers, humidifying and ultrasonic diffusers, nebulizing diffusers. Diffusers are simply a way to get the aroma of an essential oil into the room. Each type of diffuser has different uses.  However, the only one that is truly therapeutic is the Nebulizing Diffuser.


Candles are possibly the best know way to diffuse aromas into the air. We may not think of candles as diffusers, but they do diffuse aromas.

However, candles really do little to nothing in terms of offering any health benefits. Actually many candles are made with synthetic oils. Synthetic oils are cheaper than natural essential oils. They can actually be harmful. It is best to use soy or beeswax candles.

Simple Ceramic Diffusers

In this category, we can add using a cotton ball or Kleenex and placing a drop of essential oil on it. Ceramic Diffusers are small and porous in order to hold the essential oil. It is better for the Ceramic Diffuser that we call Florins to have one side glazed so that the essential oil doesn’t flow all the way through it. This is especially important when placing the ceramic on furniture because essential oils can damage furniture.

Heat Diffusers

Heat diffusers heat essential oils in order to get them into the air. The oils are placed on a receptacle that is heated. Keep in mind that when oils are heated they can lose their therapeutic properties. Therefore, using a Heat Diffuser has no therapeutic value, but it can make a room smell good

Ultrasonic or Humidifying Diffusers

Ultrasonic diffusers also create a fine mist as does the Nebulizing diffuser. However, they do so by creating a very fast vibration rate of a small disk that is under water. So this type of diffusers uses water and the fine particles of the essential oil are diffused into the air like a mist. These types of diffusers do have a therapeutic effect on the body. However, they are not as effective as the Nebulizer.

Evaporative diffusers simply use a fan to blow over a pad/filter on which essential oils are placed. This causes the essential oil to evaporate quickly. Because of evaporation is very fast, the entire essential oil is not dispersed at once. The lighter chemicals of the essential are dispersed first and the heavier chemical components are dispersed at the end of the evaporation process.

You find evaporative diffusers with fans for cars, in ceramic pendants, wood pendants. They are similar to the Ceramic Diffuser.

Nebulizing Diffusers

Nebulizing Diffusers are used for therapeutic benefits by aromatherapists. As a matter of fact, they were once used in French hospitals. However, you must be careful not to over saturate a room. This is very easy in a small space and is very bad for those in the room.

Since the Nebulizing Diffuser breaks down essential oils into micro components, these tiny components get into the lungs and can possibly do damage to them. To avoid this and receive the diffuser benefits, turn off the diffuser in 10 minutes or put it on a timer. By the way, Nebulizing Diffusers are more expensive than the other diffusers discussed above.

In another article, we will discuss the types of essential oils appropriate to use in a diffuser and how to clean the diffuser.

Happy diffusing!
