Ultrasonic essential oil diffuser is a device used to disperse essential oils (highly concentrated extracts of flowers, leaves and other plant parts) into the surrounding air.
The diffuser uses electronic frequencies to vibrate in the water, generating fine water mist and essential oils released into the air. Because it uses water, some people use them in winter to help humidify dry air.
According to ancient aromatherapy, spreading fragrance through the air allows essential oils to activate odor receptors in the nose, transmit information to the brain, and affect your mood and nervous system. You can add your favorite essential oils, or you can DIY favorite scent.
