Know before you buy
The 600m is a bypass humidifier that mounts directly to your furnace ductwork. It utilizes your existing HVAC blower fan to distribute moisture-balanced air throughout your home's entire duct system.
While it is designed for homeowners with some DIY experience, installation requires cutting into your HVAC ductwork and wiring the unit to your furnace. If you are not comfortable working with sheet metal and low-voltage electrical components, we recommend hiring a professional HVAC technician.
Maintenance is minimal and generally involves replacing the water panel evaporator once per heating season. You should also perform a quick annual cleaning of the unit's internal components to ensure optimal performance and prevent mineral buildup.
The included manual humidistat is mounted to your return air duct or a wall, allowing you to dial in your preferred humidity level. Once set, the unit will automatically cycle on and off to maintain that specific level based on the indoor air conditions.
The Aprilaire 600m is rated for homes up to 4,000 square feet. It is best suited for homes with forced-air heating systems where you want to protect wood floors, cabinetry, and furniture from the damaging effects of dry winter air.
No, the unit operates on 24V power, which is typically supplied by your furnace control board. It draws very little energy, requiring only 0.5 amps to function.
