Our Ultrasonic aroma diffusers deliver the next generation of aromatherapy dispensing for your home or work environment. Unlike candle or other heated aromatherapy diffusers the aroma materials are dispensed safely at room temperature and not denatured by heat. Oil is floated on water which is vibrated by ultrasonic frequency to created a discrete microfine mist of aroma. A built in timer can be set for up to 2 hrs run time or until auto off sensors detect low liquid levels. It can also be set to rum for up to 10 hours run time of intermitent bursts on a full charge of liquids. Accessory LED light lamps of varying colour and intensity settings can also be optionally activated to enhance mood setting. Classical elegant minimalist styling compliments any decore.
