1.37 Gal. Cool Mist Digital Humidifier for Large Rooms Up To 400 sq. ft

Breathe easier with the Air Innovations Ultrasonic Cool Mist Digital Smart Humidifier - Model 505. For its size, it runs longer and it's more versatile than any other humidifier on the market. This fully featured unit has a 1.37 gallon tank the runs up to 70 hours on low - that's almost 9 nights of sleep before you have to refill it. The operation of this humidifier is silent for a peaceful night of sleep, yet it's powerful enough to add humidity to large rooms up to 400 sq. ft. Other features include: the entire tank and base are made of antimicrobial plastic to help prevent mildew, mold and bacteria growth, built-in programmable humidistat that monitors and maintains the humidity levels that you set, a permanent ceramic filter that traps impurities from water, and a 360 degree rotating mist nozzle helps direct the moisture where you want it.
