Enjoy aromatherapy with Plantlife's Ultrasonic Diffuser, a beautiful faux wood grain and intricate lattice design, that compliments any decor! With a large 400 ml water capacity, 3 mist modes of high, low and intermittent which allows for an long diffusing time period. This Diffuser has 4 vents on top for the dry mist to enter the air and circulate into big spaces. Features include auto shut-off and 7 different color LED light settings to enhance the nighttime ambiance. Ultrasonic offers the best way to diffuse essential oil as its "no heat, dry mist" technology preserves the therapeutic properties of the oil. Ultrasonic Technology uses high-frequency, low-energy vibrations that break the essential oil into tiny micro particles. These micro-particles are dispersed into the air and are easily absorbed by the body for a greater therapeutic effect. With this technology, less essential oil is needed for maximum therapeutic benefit.
