The AprilAire 600 Large Bypass Humidifier is a high-capacity whole-home humidifier designed for larger homes that need stronger moisture output during the heating season. Installed directly onto your HVAC ductwork, it delivers consistent, balanced humidity throughout your home using a simple and proven bypass design.

With the ability to deliver up to 17 gallons of moisture per day, the AprilAire 600 uses warm air from your furnace to naturally evaporate water and distribute humidity evenly through the duct system. It operates quietly, requires no electrical connection, and helps reduce dry air symptoms like static electricity, dry skin, and cracking hardwood floors.
