What is a Mini Essential Oil Diffuser?

As it sounds, a mini essential oil diffuser can do everything a regular essential oil diffuser can do but on a more compact scale. It’s a more compact version that doesn’t put out as much of the essential oil scent or droplets when it runs. This can make it ideal for using it in smaller rooms like the bathroom, closets, or in something like an RV.

You can typically find mini essential oil diffusers in the same styles that you’d find the regular diffusers in, and this is great because it can save you from testing out multiple ones when you’re trying to find the best fit.

Basically, this mini diffuser works to spread microscopic droplets of oil throughout your room. Some have you mix essential oils, and water and others use plain essential oil. They’re a good alternative to use if you want something that will only run for a few hours before it shuts off.

How Mini Essential Oil Diffusers Work

How your mini diffuser works depends on the type of diffuser you get. They come in several different categories, but they all work to disperse the essential oils throughout your room in your immediate area. Four big categories are:


This type of diffuser utilizes a small fan to change the essential oil from a liquid to a gas before pushing it into the surrounding air. You put the essential oils on filter or pad below the fan and switch it on. They quickly disperse the oils through your air.


Heat diffusers are quiet and inexpensive. They use heat to disperse your essential oils throughout your room, but the heat changes the oil’s molecular makeup.


Nebulizers use an atomizer to help break down the essential oils and disperse them into the air. It doesn’t use water or heat to do so, and this allows you to get stronger scents. Also, the tiny molecules are easier to absorb into your body.


Ultrasonic diffusers have parts that vibrate at a very fast frequency. These frequencies are what dispel the essential oil into the air. They mix oil and water to work, and this means that this diffuser can double as a humidifier in any room that you run it in.

Buying Points to Keep in Mind When You Shop

Once you pick a diffuser, you’re ready to start comparing various mini essential oil diffusers. This will help to ensure that your new diffuser works as you need it to work.


Your diffuser’s design gives you direct clues to how well it’ll fit into your lifestyle. Since the diffusers in my guide are mini, they’re small and lightweight. You have to decide whether or not you plan to take your diffuser with you or use it largely at home. For home use, you can find a diffuser that suits your home’s colors and decor. For travel, having one that runs on alternate power sources is a must.


Your diffuser’s ease of use or the functionally should be at the top of your list. You don’t want to spend ages trying to get your diffuser set up and running, and a user-friendly option with a straightforward design is a good idea. Consider whether or not you plan to monitor your diffuser if you choose one with a heat source, and it’s also a good idea to check how long the diffuser runs for between fills.


Your mini diffusers tend to have a lower point of gravity due to their compact size, but stability is a must. You don’t want your diffuser to tip over if you should happen to bump it and get your essential oils or oil and water mixture all over. Look for a diffuser with a wider base that tapers up to a more slender top.

Timer and Safety Features

Even mini diffusers come with times built right into them. They allow you to set your diffuser to spray or run for 30 minutes, an hour, two hours, three hours and more. Most mini diffusers can run for a maximum of four to six hours before they shut off. Automatic shutoff should be a safety feature you want to avoid burning out your diffuser.


Although we outlined the various types of diffusers earlier, it’s a critical part of the decision making process. For example, a nebulizer can help you unleash your oil’s full potential while an ultrasonic diffuser comes with a humidifier to add moisture into your air. Candle diffusers are also available. However, we do not recommend these diffusers because an open flame is dangerous.
