The Air King Digital Recirculating Humidifier 9929 combines a very large tank capacity (4.5 gallons) with high output capability (9 gallons per day), making it truly a whole house humidifier.

The maker claims it can handle up to 3200 square feet. For a large unit, this model was relatively quiet--but you wouldn't want to put it anywhere near a bedroom. This unit includes a digital humidistat for accurate humidity settings and automatic control. For even greater capacity, check out Air King's 9955 model. It can release 12 gallons in a day and has a 6-gallon tank. Otherwise it is very similar to the 9929 model.

The Air King Digital Recirculating Humidifier 9929 comes with castors for mobility, a 7.5-foot cord, grounded 3-prong plug, and one filter. The filters last from 4 months to 1 year, depending upon conditions.
