What is a Diffuser?
Do not confuse a humidifier with an essential oil diffuser. Diffusers are different from humidifiers in that they are specifically designed to take drops of essential oils, mix the oils with the water in their tanks, and distribute. There are four types of essential oil diffusers: ultrasonic, nebulizing, heat and evaporative.
They are designed for vaporizing a fine mist using the essential oils with a cold effect to aromatize the room area.
