AprilAire Model 865 Steam Humidifier

Whole-House Humidifier With Fan Pack

Our whole-house steam humidifier automatically adds moisture to your home through the use of a dedicated wall vent and fan pack. Steam is created by heating water inside the humidifier and delivered to the fan pack remotely.
