types of essential oil diffusers

With so many options to choose from due to the growth of the essential oil diffuser market it's important to have an understanding of the different types, that way you can choose the one that best fits your needs. If you have not read our blog post about Aromatherapy Oil Diffusers, be sure to head over there to get an idea of how they work.

If you are familiar with them, then continue to read this post about the different types. If you recall from our post on Aromatherapy, we discussed the purpose of essential oils, so let's now put it all together and discuss the different diffusers, that way you can buy the one that best suits your needs. Personally, I think it's easiest to start with understanding the Neutralizing Diffuser, so that's where we'll begin.

Nebulizing Essential Oil Diffuser(s):

These types of oil diffusers do not use or require heat, or water. So how do they work? Nebulizing diffusers work by creating a forceful air current that moves through a small tube, and from there, pressure is created that acts as suction, strong enough to cause whatever essential oil has been added to rise and then be dispersed as a fine mist. So think "force" when thinking about the operation of these oil diffusers, as oppose to some of the others we will discuss. There are a large variety of these types of diffusers, and some of the benefits include low to no plastic usage in the designs, as well as these types of essential oil diffusers are extremely concentrated because it eliminates the need for water, diluting the essential oils.
Many of these diffusers can also be set to timers to disperse the vapors at specific times. As usual, some of the concepts to think about are; how large of a room you wanting to cover, timer feature, noise level of the device, what's the upkeep (cleaning), how does it run (plug in, and stationary or more portable?). So it's important to read reviews and make sure to browse around before making your selection.

Ultrasonic Essential Oil Diffuser:

When thinking about ultrasonic diffusers, I want you to think "Vibrations", because that's really how the ultrasonic essential oils diffusers work. They get the name "ultrasonic/no heat" because they use ultrasonic vibrations to break down the added oils into extremely small particles. These particles are then dispersed into the air as a very fine mist with the help of steam, and that's essentially how you are getting the aroma. Now, the term "steam" usually means there is some sort of heat source, however ultrasonic diffusers don't use heat, this process of creating a fine mist without the use of heat is because they use what's called adiabatic process.
In simplest terms this means that no heat is gained or lost by the system. Like many types of diffusers, these come in a variety of shapes, sizes, and designs at varying price points depending on what exactly you're looking for, how large of a space you want to accommodate and the features you're inevitably looking for. Because this type of system does use water, oil, and many of these devices use plastic in there design, it's suggested that they need more regular cleaning and maintenance to hold up for the long haul. This is something to think about as well when purchasing an ultrasonic oil diffusers.

Evaporative Essential Oil Diffusers:

When discussing the different types of Essential Oil Diffusers on the market, these right here are probably the easiest ones to replicate if you're looking for a cool DIY project. A reed diffuser is an example of this type of essential oil diffuser. Rattan sticks are used in this case, placed in an essential oil and then the oils travel upward toward the top of the sticks releasing the aroma. So the once liquid oils are turned to more of a gas. The one thing to keep in mind with evaporative or reed essential oil diffusers is that they typically do no cover as large of an area as other diffusers, and there options are much simpler and less flexible.


Some of these diffusers make use of a fan as well to help disperse the aroma farther, in hopes to cover a larger area which also causes the oils to evaporate quicker. I personally use these types of diffusers in smaller areas, like a powder room or small office. It's important to note the oils used may alter some of the processes that take place with evaporative diffusers because typically the lighter the oil the faster the dispersion of the oil.

Heat Essential Oil Diffuser: 

There is no real guessing here, heat aromatherapy diffusers use heat to help disperse the oils. So the oils are still evaporating, however a heating element is added to help aid in the evaporating process. Some however say that if the element used is to hot, the chemical makeup of the essential oils can be changed causing a change and offset of the aroma. I've found that the heating type essential oil diffusers that use a lower heat have no real effect on the aroma and actually work quite nicely to disperse the aroma. Once again, a lot of the choices here are based on preference and where you intend to use the diffuser, Make sure to read reviews and go with a reputable brand.

Candle Essential Oil Diffusers:

In some ways you could categorize these as heat diffusers because essentially that's what they are using. However, the heat is coming from that of a lite candle and not a heating element. Oils are simply added above a lite candle, which are then heated to disperse the aroma within a given space. Again these types of essential oils diffusers, like the evaportaive diffusers, work best in a smaller space or a space that's essentially more closed-in.
