This elegant Aroma Diffuser, Humidifier and Night-Light creates a wonderfully soothing atmosphere with soft changing colours and a calming stream of mist. The sleek design is suitable for any room and perfect for use when sleeping. The advanced ultrasonic diffuser has no heating elements and produces a natural cool mist and therefore does not effect the composition of the oils as no heat is involved. The unit can be set to automatically switch off when the water runs out or run all the way through the night as a night-light. Ideal for use with our pure essential oils, pure essential oil blends and fragrance oil ranges.
