That leaves you with a big problem, which diffuser do you choose? Which best meets your needs? We provide you with the five best essential oil diffusers from our research. There are about three categories of essential oil diffusers: the ultrasonic, the nebulizing, evaporative.

Generally, ultrasonic essential oil diffusers are often chosen above other kinds for certain reasons. Chief among the reasons is that they make less noise when in operation.

Also, they do not produce heat when in operation. Ultrasonic units use 2.4 million vibrations per second to turn oil and water into a mist.
