The Aprilaire model 600 humidifier is a whole-home solution that helps you achieve total comfort through humidity control. The model 600 uses the furnace blower to move air through a Water Panel. It is installed by a local HVAC professional. The Aprilaire automatic digital control mounts on your heating system and features Auto -Trac to automatically deliver the optimal amount of humidity, regardless of conditions. It features a convenient display and indicators to let you know relative humidity (RH) levels, operation status and any service needs. For a more precise humidity control and preservation, we suggest the wall mounted digital display humidistat.
