Glass Heart Ultrasonic Air Diffuser


Our new range of contemporary ultrasonic diffusers are a  sleek and stylish way to diffuse your favourite fragrance combinations.


Ultrasonic Diffusers utilize 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.


We currently don't stock our own essesntial oils or fragrance oils but we will be shortly with all your favourite scents.
