Our Testing Procedure

We spent three weeks trying and testing 15 essential oil diffusers on Amazon that include ultrasonic diffusers, nebulizers, and more. We quickly rejected a few of them due to their undesirable design that makes usage inconvenient. Some of them are bulky that occupy a lot of area and others have buttons with challenging navigation (we can’t use them without taking the help of the user manual).

We noticed the diffusers working side by side to visually make the difference between the height and size of the streams of mist along with the main factors “how efficiently they to diffuse oils. Then, we operate them for several hours to confirm their effectiveness to make the space fragrant like essential oils.


Scientifically determining the precise effect of each products was beyond the scope of this review, but we observed the plume size and took subjective notes on aroma, which generally provided us a clear view of which oil diffusers worked better.

To find everything that could probably be annoying about the design and performance of any diffuser, we put them in every location such as kitchen, living room, guest room, and bedroom. We also tested them in a dark room at night to observe the brightness of the LED indicator lights (obviously tested those model that have LED lights).

When testing nebulizers, we observed the noise levels. When any of them is set on the full blast, a buzzing sound is heard. The best models enable you to rotate so that the sound becomes almost inaudible. One of the downsides of turning the nebulizers is that the stream of the mist also becomes weak.

OIL Diffuser Buying Guide

Factors to Keep in Mind by Purchasing the Best Oil Diffuser


One of the great essential oil diffusers benefits is that it serves as a home décor product. Therefore, the design makes a difference. Most people will buy the common semi-translucent plastic diffusers, but you can choose from a range of oil diffusers that are designed from other materials, such as ceramic, fake/real wood, and porcelain. Generally, good-quality diffusers come at a high price. We suggest you to buy ceramic oil diffuser as they look stunning in your home.

Tank size:

More than other details of your oil diffuser, the size of the tank determines how you will use it. The tank sizes of Ultrasonic diffusers range from 100-500 millilitres. The best diffusers combine the advantages of larger size with smaller footprint. Usually, bigger tanks give thicker mist and extended runtimes without any requirement of refilling. If your room size is large, then we suggest you go for an oil diffuser with a larger tank for effective diffusing.


The more powerful your oil diffuser is, the thicker stream of mist it will produce. Irrespective of the tank size, we wanted to test their power that is how strong stream of mist they produce. We looked at the stream of mist produced by each oil diffuser side by side and it was so interesting to watch it.


The most convenient to use and clean diffusers feature only one lid. Fancy diffusers are designed from materials other than plastic generally have two lids. One of them is practical and the other one is decorative. You may find it annoying when it comes to cleaning the lids, but this does not mean that it’s not worth your money. They make the best choice for occasional use.


Many models of ultrasonic diffusers come with lights for an added charm, often produce rainbow colors. You may find colors soothing or too bright, depending on your liking. Fortunately, they can always be switched off whenever you want.


Some medium and large-sized diffusers feature a timer, which will turn off the oil diffuser after a few hours. This feature enables you to use the essential oil diffuser multiple times without refilling the water. It’s a functional option but not necessary.

Intermittent Oil diffusing:

It’s great when you’ve a choice for the diffuser to spray or mist oil for a particular amount of time and then let it take rest. This pattern is famous as intermittent diffusing; it allows the diffuser work for longer just on a single fill.


What are the types of diffusers?

Essential oil diffusers come in a variety of styles and functions. You can go through them below:

Ultrasonic Diffusers

Ultrasonic diffusers are so far the most famous and convenient way to use essential oils. They freshen up the air in your room by releasing a deep mist of essential oils.

Vaporizers heat the essential oils to the appropriate temperature until they get converted into vapors. You’ll find two different types of vaporizers on the market that include electric vaporizer and tea light vaporizer.

Tea light vaporizers use a small number of essential oils and water until it vaporizes.

However, the heat tends to modify the formula and qualities of the essential oils. On the other hand, electric vaporizers operate differently. There is no requirement of water, and the dish is heated to a constant and right temperature without making any change to the composition of your essential oils. They work continuously until switched off.

Nebulizers are the new launch in the industry of essential oil diffusers. Unlike most oil diffusers, they don’t use water or heat. They perform by atomizing the aroma oils into fine molecules.

These are the most potent method to diffuse essential oil and preserves the natural quality of the oils. A large amount of essential oils is required in nebulizers and they run for a shorter time period. However, the concentration of oils released into the air is too stronger.

One important factor to keep in mind when purchasing nebulizers is that they can’t work with viscous oils that are derived from trees and roots. Those who wish to utilize some of those viscous oils have to dilute them with any essential oils and must possess an advanced aromatherapy knowledge.
