This device humidifies up to 3,800' sq. to eliminate dry air throughout an entire home. The humidifier's deeply pitched fan blades and a specially designed air duct create an invisible stream of moist air that circulates from the floor to the ceiling. The humidifier emits up to 12 gallons air moisture every 24 hours and the integrated humidistat automatically maintains the humidity level you set. The humidifier holds up to 6 gallons and continuously circulates water through a filter that removes hard minerals and water deposits. A removable 2 1/4-gallon jug refills easily under a faucet and when it's placed back in the humidifier it automatically refills the 3 3/4-gallon reservoir. The humidifier has three fan speeds, four casters for easy mobility, and a remote control. 23 1/2" L x 15 1/2" W x 20 1/2" H. (13 lbs.)
