Product details

Breathe easier with the Air Innovations Ultrasonic Cool Mist Digital Smart Humidifier - Model 505A. 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: 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. It also features a fully programmable timer that turns on and off when you want it to, top and bottom handles for easy filling and carrying, extra wide opening for easy filling, and an auto out-of-water shut off when it runs out of water.
