There are several different types of essential oil diffusers on the market. For this article, we focused on ultrasonic diffusers. Based on our research, ultrasonic diffusers are best for diffusing essential oils because they do not utilize heat in the production of vapor. Since heat can have a negative effect on essential oils, ultrasonic diffusers are the best way to get the full benefit of diffusing essential oils.

Ultrasonic diffusers work by vibrating the water in such a way that it vaporizes into the air. Since the essential oils are mixed into the water, they are carried along with the water. Ultrasonic diffusers generate the vapor without any heat, which best preserves the integrity of the essential oil.

Diffusers are better than any scented candle, because you can put more than 100 different essential oils into them. You can even combine two or more essential oils to create a unique blend.

The difference between a diffuser and a humidifier

While a diffuser does add a small amount of humidity into the air, it still functions notably different when compared to a humidifier.

A humidifier’s primary function is (unsurprisingly) to add humidity into the air. To do this, it utilizes a relatively large tank of water (typically measured in gallons) which is then heated and released into the air.

An essential oil diffuser has a much smaller tank of water, usually somewhere between 80ml to 350ml. This means that the humidifying effects of a diffuser are relatively minimal when compared to a humidifier. However, a diffuser is significantly better at getting essential oils into the air. In fact, usually it is not cost-effective to use a humidifier to diffuse oils at all.

For those who want aromatherapy benefits and humidity, it is best to use an essential oil diffuser and a humidifier.

Benefits of essential oils

Essential oils have been used for thousands of years, from cultures as far-reaching as Ancient Egypt and India. These oils have been used for a variety of purposes, from spiritual to medicinal, and there are a significant number of modern scientific studiesthat support the theory that essential oils can be beneficial in a number of very real and quantifiable ways.

The following are just a few examples of the types of benefits that essential oils can provide:


Eucalyptus has been used across many cultures and is often used in over-the-counter medications. When placed near the sinuses or on the chest it helps with congestion and sore muscles. Eucalyptus is particularly useful for diffusers like the ones we are testing — especially when used for congestion.


Lavender is typically used for bruises, cuts, and skin irritation. Studies also show that the scent can reduce levels of the stress hormone cortisol. Application on the skin has its uses, however lavender is popular for diffusers because it can create a soothing, relaxing scent in a room.


Used in many OTC remedies, peppermint can also be used as an essential oil in tea or other beverages, and also as a way to soothe the stomach. Studies show that peppermint increases oxygen levels in the blood, and can help a person be more aware.


Tea tree oil is commonly used directly on the skin, and can be used for everything from acne to fungal infections.


There are literally hundreds of essential oils to choose from, some more useful than others. We recommend you do some research to find a few essential oils that will work best for you. In our article researching and testing essential oils, we discovered quality can greatly vary by brands. Proper use and selection are required to maintain safety and to properly enjoy the benefits of these oils.
