How Essential Oil Diffusers Work

In the past, you had to diffuse essential oils the low-tech way by putting them in an oil diffuser that used a candle or other open flame to heat the oil. These days, you can use an electric essential oil diffuser to get the aromatherapy benefits with little effort. Diffusers work by breaking down the oils into super tiny particles with ultrasonic vibrations, and then they spray the particles into the air, letting the oils be more easily absorbed in the lungs. The best essential oil diffusers are also humidifiers, and they deliver scent and cool steam as well. Most of these models have a water reservoir and a sponge or cotton batting that absorbs the oils. The steam moves through this to carry the micro-particles of oil into the air.

Now, onto our list of the very best essential oil diffusers out there today. From portable diffusers for your desk at work to diffusers that can fill a whole yoga studio, there’s a device to meet your needs.
