With comfort you can see and feel, the Vornado UH200 Ultrasonic Humidifier brings a new look to home comfort. Powerful whole room circulation evenly distributes humidity throughout the whole room (up to 900 sq. ft.) without pooling water on the floor. The UH200 automatically maintains your comfort level with its built-in humidistat, while the SimpleTank System makes carrying, filling and cleaning the tank, well, simple — 1.75-gallon capacity and 4-gallon output every 24 hours. Easy-to-use touch controls, 2 fan settings (High, Low and Auto), a humidity sensing remote — comfort made simple.
