The Evap3 Evaporative Whole Room Humidifier creates a comfortable, perfectly humidified living space quickly and quietly. Vornado’s deep pitch blades pull large volumes of harsh, dry air through two humidifying wicks, and then, using Vornado’s signature Vortex Action, circulates the humidified air throughout the room, providing complete and uniform humidification in spaces up to 700 sq. ft. The easy-to-use push-button panel allows you to choose your desired humidity level and fan setting. A large 1.5-gallon capacity makes for fewer refills. 2.6-gallon output every 24 hours. A black and grey color scheme makes this model as sleek as it is effective.
