Overview

A bedroom, nursery or office is the room for this round white humidifier. Water goes in through the top opening without turning the tank over, and an ultrasonic plate makes the cool mist.

The wide opening makes filling and cleaning easier, and the unit shuts itself off when empty. The title mentions a large room, but the stated coverage is a modest floor area.

Who it's for

Light sleepers and parents of babies who want a quiet unit with easy filling fit this model. Owners of large rooms should check the floor area before relying on the large room wording.

Performance notes

An ultrasonic plate turns tank water into mist, and a nozzle directs it into the room. Coverage is set by the stated floor area, so a bigger room will see less change. A cleaning brush is supplied for the wide tank opening.
