  • Convenient digital control shows the perfect humidity. Additionally, lights indicate when the unit is running, when to change the water panel, and when service is needed.
  • Our Bypass Aprilaire Home Humidifier will maintain optimum humidity for your home. Such maintenance will reduce the incidence of respiratory infections and symptoms.

The Best Automatic High Output Furnace Humidifier

Aprilaire introduced the first evaporative humidifier for forced air furnace systems back in 1954. Aprilaire continues to be the leader in whole-home humidification systems. The Aprilaire 600 Automatic Bypass Home Humidifier works by piping water into the distribution tray. From here, the water is uniformly distributed across the width of the plate, then through outlets. Lastly, dry, hot air from the HVAC system moves through the moisture-laden water panel evaporator. Natural evaporation occurs, then the water is turned into vapor and released into the air to circulate throughout your home.
