About this item

Product details

The Mainstays Ultrasonic Oil Diffuser brings a simple way to add scent to the rooms where you spend your time. Its compact cone form fits easily on a shelf, nightstand, or desk, and the 150 ml reservoir gives you room to set up a session before refilling. Ultrasonic technology turns water and oils into a fine, quiet mist, so you can use your own essential oils by refilling the diffuser with water and a few drops of oil. A soft LED glow adds a gentle ambient light while the diffuser runs, giving the piece a warm presence in an everyday home setting.

Works very well for a small space like by bathroom during the day. Has two settings, continuous or every 30 seconds. Our bathroom is immediately off our kitchen so I used this during a recent party to keep things fresh. The color changing light is also nice for ambiance if you're using this in a teen room. I use it primarily during the day without the light. Very quiet. Easy to use, not a lot of guessing or too complicated.
