Lately, at work, it seems I cannot make it back to my desk without first venturing through a cloud of scented mist. If this is also your experience then you have, like me, also entered the age of Essential Oil Diffusers. At first, this sudden change was annoying as I found myself asking, why can’t we just breathe normal air. As time has gone by, I have actually grown to like these new machines.

In this article I will outline some basic information about Essential Oil Diffusers for those who want to better understand where these unusual machines came from. Also, if you are looking to purchase a diffuser, I will recommend the diffusers that I think are the best on the market so that you can make a more informed decision.  

What is an Essential Oil Diffuser?

Essential Oil Diffusers have rapidly grown in popularity over the past few years. Consequently, It seems every millennial’s desk has a unique version of this machine. But what is a Diffuser and how have they become so popular? A Diffuser is a tool used in Aromatherapy to release essential oils in-to the air. You can put different types of oils and scents in your diffuser to change your mood. This idea of manipulating your mood with scents comes from Aromatherapy. Feel free to follow the link below for some examples of common aromas used in Aromatherapy and the effect that they have on your mood.

How Essential Oil Diffusers Work

There are three main types of Essential Oil Diffusers; Ultrasonic, Heat, and Evaporation.

Ultrasonic Diffuser

The most common type of diffuser is an Ultrasonic Diffuser. It operates using small vibrations that break the solution in-to tiny particles. Then, the Diffuser sends these particles in-to the air around you to create lovely aromas. 

Heat Diffuser

Additionally, some Essential Oil Diffusers operate using heat. Basically, a Heated Diffuser slowly drips the essential oils on to a heated element that turns them in-to a vapor. Then, these vapors are released in-to the air. This kind of Diffuser can change the composition of the oils. Therefore, the fumes inhaled from these Diffusers may have a different effect on your mood than unaltered Essential Oils. 


Lastly, another type of oil diffusion method is the evaporation method. These Diffusers release oil in-to the atmosphere by quickly evaporating them with a stream of air. They use a fan that blows air over the oil and water mixture. 

Most Essential Oil Diffusers on the market today are ultrasonic as this seems to be the safest and most efficient way to release the mist in-to the air.  

Why buy an Essential Oil Diffuser?

Diffusers are basically a way to make aromatherapy more convenient. Yes, they can be used to mask a stinky room but the oils used to do so come from aromatherapy. So, what are the benefits of aromatherapy? Well, for centuries ancient cultures such as China, Egypt, and India have used plant extracts for medicinal purposes. They did this by distilling or pressing oil from common plants like lavender, rosemary, lemon or peppermint. Aromatherapy patients inhale scents from these oils. Though it is not fully proven, aromatherapy has been said to help with pain management, sleep quality, stress, headaches, and a whole list of ailments.

So, if thousands of years of medicinal practice and hype is not enough to sway you in to aromatherapy, maybe the experience will. Take it from someone who started as one of the biggest skeptics out there, the aromas are well worth a try. Even if you don’t believe that aromatherapy will improve your health, a room that smells like lemon zest is better than one that smells like dirty socks.

Nonetheless, the original question is why buy a diffuser? You should buy a diffuser if you want to try aromatherapy. A diffuser allows you to do this without having to handle, massage or otherwise prepare your own essential oils. All you need to do is fill your diffuser with water, put in a few drops of your desired oil, put on the top and press the power button. They are also a great way to freshen up a smelly space.

Essential Oil Diffuser Maintenance

Diffuser maintenance and cleaning can differ depending on which one you own. Nonetheless, it is important to keep a clean device. This will help your machine last longer and operate more smoothly. Additionally, cleaning your diffuser will prevent harmful bacteria from being released in to the air.

Experts recommend that you clean your diffuser once per week. Generally, you can clean most diffusers by filling them with a mixture of water and vinegar. Once you have filled your diffuser, turn it on an allow it to run until it is almost empty. Then, take a small cleaning device like a Q-tip or tooth brush and clean all of the surfaces inside the device. Wipe out any extra residue and then allow your diffuser to air dry while open. Your essential oil diffuser should now be clean and read to use again. Please see the video below for a tutorial on the cleaning process.
