An ultrasonic diffuser is an aromatherapy diffuser that uses electricity to disperse essential oils in the air. It breaks down essential oil particles into their base molecules. These molecules are negatively charged, so they disperse, joining the positively charged molecules in your home. Ultrasonic diffusers use water as a transfer mechanism but are not dependent on steam. Instead, the oil sits on top of the water, and ultrasonic vibrations are created to agitate the water, causing the oil molecules to separate and releasing the negative particles into the air with a fine mist.
