DetailsChoose the Model 400 with automatic digital control to maximize your humidity control with minimal water.
The Aprilaire Model 400 Whole-House Humidifier features a built-in bypass damper and utilizes new evaporative technology to minimize water use.

- Truly automatic control
- Eliminates standing water, making it the perfect choice for homes with septic systems, locations where a floor drain is not available or families interested in water conservation
- Has an evaporation capacity of 0.70 gallons per hour
- Humidifies tightly-constructed homes up to a 4,000 square foot in size
The Aprilaire digital control can be used in manual mode while still providing vital service, temperature and relative humidity indicators.
