    Aprilaire provides all of these advantages. Here, briefly, is the method: The Aprilaire Humidifier (except the Models 350 and 360) is installed to operate in conjunction with the furnace blower motor. When the humidistat or Automatic Humidifier Control calls for humidity and the blower motor is operating, water flows to the distribution pan located at the top of the unit.
