Furnace humidifiers are connected to the hot air supply duct on a furnace and a cold water supply line. An circular drum pad, called an evaporator pad, located in the humidifier picks up the water from the supply line. The water then evaporates and enters the furnace blower, where the hot air holds onto the water vapor. When the furnace blower sends the hot air through the house it increases the humidity in the air. Disconnect your furnace humidifier for cleaning, to make repairs or to replace it with a new model.

The tray is kept full of water with a float switch, which allows the water from the plumbing system to enter the tray when the water level drops. When the humidistat is turned up or the humidity level drops, a small electric motor rotates the sponge drum through the tray, absorbing water. Some of the air moving through the ductwork blows across the sponge, picking up moisture. This moist air moves through the ducts and into the rooms.
