Understanding How Essential Oil Diffusers Work

At the most basic level, essential oil diffusers work by dispersing essential oils into the air to be inhaled and easily absorbed by the body.

As an added benefit, most essential oils also emit a pleasant scent into the air when disbursed via a diffuser. It also purifies the air, killing bacteria and fungus.

What is an ultrasonic diffuser for essential oils?

Ultrasonic diffusers dispense healing essential oils into the air as negative ions. These diffusers get their name from the ultrasonic vibrations used to break down the essential oils into microparticles, allowing the oil to be dispersed as a very fine mist, mixed with steam, into the air.

The process does not create a lot of noise, allowing the diffuser to run extremely quietly – ideal for relaxing, sleeping, and working.

Does an ultrasonic diffuser use heat?

The ultrasonic aroma diffuser process is adiabatic, meaning that the oil changes state without the use of heat. Because no heat is used in the process, the integrity of the oil is fully preserved upon dispersal.

Can an ultrasonic diffuser double as a humidifier?

Yes, an ultrasonic diffuser uses water as part of the dispersal processes, adding the benefit of humidifying the room.

The added water is sometimes criticized as it dilutes the potency of the oils, but for those who do not prefer overwhelming smells and for their oils to last longer, mixing them with water for dispersal can be seen as a good thing.
