Our take on the Ultrasonic Aroma Diffuser (12 oz)

A 12 oz ultrasonic aroma diffuser in a round, marshmallow-shaped polypropylene body with a warm LED glow. It runs cool mist from plain essential oils and offers 30-minute, 1-hour, 2-hour and 3-hour timer settings, plus two warm light levels. It is sized for rooms of roughly 200-250 sq ft and beeps when the tank runs dry or needs cleaning. Against typical diffusers it trades app control and large tanks for a simple, quiet, design-led package that suits bedrooms and offices.
