What Is a Diffuser?

This is a good starting point before we talk about diffusers themselves. These devices work by sending essential oils into the air. This allows people to breathe in the vapors so their bodies can absorb them. Other benefits are they add a pleasant aroma into the air and also remove fungus/bacteria for air purifications.

There are different kinds of diffusers you should know about. While they work using the same basic principle there are differences in how they aid the oils into the air. They also have pluses and minuses to note.

NEBULIZER: It’s often argued that this releases essential oils in their most natural form. The reason is the oil concentration that’s made. This happens by using force to break down essential oils into atoms. The process works like a perfume bottle.

HEAT: This diffuser heats up essential oils until they then evaporate in the air. Some good options are sandalwood since they can spread well into the room when using this kind of diffuser.

Several kinds of heat diffusers are available. They include electric, candle, and lamp ring. However, they function by using a tray. The oil evaporates after the source heats it up.

ULTRASONIC: An Ultrasonic diffuser sends essential oils out into the air as something called “negative ions.” They’re named due to the “ultrasonic vibrations” that break down essential oils into tiny particles. This turns the oil into a super-fine mist with steam.

One effect is little noise is produced. This helps to provide a relaxing environment for working/sleeping since the diffuser operates quietly.

EVAPORATIVE: This type uses a fan to make a wind/heat effect that causes the oil to evaporate when it enters the air. The oil is stored in a material like a wick or pad. This allows the oil to evaporate using a controlled method.
