Reviews Description: The Vornado Whole-Room Evaporative Humidifier combines the proven reliability of evaporative humidification with Vornado’s signature Whole Room Circulation. An effective, low-maintenance process, the deep-pitch blade circulator pulls harsh, dry air through the humidifier and pushes moist air further into the room, providing complete humidification. It also recovers and circulates heat off the ceiling to maintain room temperature. The easy-to-use push-button panel lets you control the humidity level and fan speed. Large 1.8-gallon capacity makes for fewer refills. Quiet operation won’t disturb your sleep.
