Opu White Ultrasonic Aroma Diffuser by Serene House

The Opu Ultrasonic Cool Mist Diffuser. The new easy-fill lid allows you to add water straight from the top of the cover. Water will flow from the openings in the Opu's lid down into the water tank. A window on the front of the unit lets you see the water level without removing the cover. Opu has three operating modes. 8-hour low mist continuous mode, a 6-hour high mist continuous mode, or a 14-hour intermittent low mist mode. Seven soft LED ambient lights relax you during your day and night. Auto shut-off is triggered when the water tank is empty for worry-free diffusing.
