Choose 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. Gravity pulls water down, while the wicking action of the Water Panel ® draws it back to the top, using 100% of the water delivered to the unit. The Aprilaire Model 400 Whole-House Humidifier:

  • 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 Model 400 Whole-House Humidifier is the newest addition to the extensive line of Aprilaire Humidifiers and may be the perfect solution for your home. For some homes, a manual control may be recommended.

The Aprilaire digital control can be used in manual mode while still providing vital service, temperature and relative humidity indicators.
