The Aprilaire® 400 Series is a whole-house bypass humidifier designed for maximum water efficiency. Its innovative drain-free design uses 100% of the water that enters the unit, making it an excellent choice for applications where water conservation is critical or a drain is not readily available. With a capacity of 17 gallons per day, it effectively humidifies tightly constructed homes up to 5,000 square feet.Operating in conjunction with the HVAC system blower, this unit uses wicking water panel technology for natural and efficient evaporation. The included automatic digital humidistat ensures optimal indoor humidity is maintained, helping to reduce symptoms related to allergies and asthma while protecting the home's interior from the effects of dry air.
