16 cm Coral & Silver LED Ultrasonic Diffuser.Unlike other Diffusers, this utilizes electronic frequencies to cause a small ceramic disc under the surface of the water to vibrate. This breaks the essential oils into tiny particles, dispersing the oil into a fine mist and creating greater fragrance concentration. They use virtually no heat energy and they will cut off as soon as the water tank is empty.Can be used with any Essential Oils.
