Types of Essential Oil Diffusers

There are a number of essential oil diffusers available, and they range from ones that you can carry in your pocket to fan-based ones that diffuse essential oils to a few square feet of space.

A variety of diffusers are described in the video “choosing essential oil diffusers”, (see it here) but the best and most effective diffusers are ones that use ultrasonic vibrations. These versions are simply safer and less mess than other (often heat-related) styles of diffusers.

There are several advantages to ultrasonic essential oil diffusers. To begin with, they allow you to absorb essential oils over the longest period of time, and they tend to use oils the most efficiently.

Ultrasonic units use 2.4 million vibrations per second to turn oil and water into a mist. Heat can break down the properties of essential oils, which makes them less effective, so ultrasonic vibrations are the best way to disperse oils.

The Benefits of Essential Oil Diffusers

Using an essential oil diffuser can also be a very safe way to make your home smell good. While children and pets can knock over or burn themselves on candles or incense, diffusers only use oil and water. The worst thing that may happen if someone bumps into a diffuser is that something will be spilled.

Although one of the most common uses of an essential oil diffuser is to provide fragrance for an area of your home, there is a wide range of other benefits to using an essential oil diffuser. Essential oils have a number of properties that could improve your health, put you in a better mood, and make it easier for you to sleep. For example, many people find that an essential oil diffuser with chamomile or lavender oils helps them sleep better.

If you struggle with respiratory issues, diffusers may also be helpful. Essential oils like tea tree oil have antimicrobial properties, and oils like peppermint and eucalyptus might be able to make it easier for you to breathe and clear out your airways. The antimicrobial properties of oils could enable you to avoid getting sick or help to speed up your recovery.

Diffusers can even be used to repel insects. Many flying and stinging insects dislike cedarwood and clove, and using a diffuser near a window may help keep pests away from your home.

What to Look for In an Essential Oil Diffuser

Essential oils can be expensive, so you want to be sure that you're getting the maximum benefit from them. When shopping for an essential oil diffuser, you should look for units that have large enough water reservoirs to allow them to run for hours without being refilled.


A large reservoir will also allow the diffuser to create enough mist to provide fragrance for the area the diffuser is placed in. Additionally, it's important that diffusers automatically shut off when they run out of water so they don't waste electricity or burn out.


A good diffuser will allow you to determine just how much mist you want. Depending on where you're keeping your diffuser, you may want more or less fragrance. There are a variety of diffusers that will enable you to change how often they release mist or how much mist they produce.


Another feature that you may want to look for is a timer that allows you to set how long your diffuser will run. You may not want your diffuser to run all night if you use it to help you sleep. Besides, running all the time may also result in the diffuser going through oils faster than you'd like.


Other factors you may want to take into account are how quiet a unit is and if it is easy to use and clean. If you're using your diffuser to relax or help you concentrate, the last thing you want is an annoying noise distracting you. Additionally, if your diffuser is difficult to use, tends to leak, or needs to be cleaned more than once a week, you may end up using it less because you consider the process a hassle.

Night Light

Finally, a number of electric diffusers also have the ability to act as night lights. Many people find dim lights to be soothing, and if you have children, you may also find a lighted diffuser to be beneficial. Diffusers with lights should allow you to adjust the brightness of the lights or to turn them off entirely.
