The panel absorbs water and maintains the proper level of hydration to support the evaporation process. Water is vaporized as air warmed by the furnace passes over the water panel. The humidified air is carried through the house through the air ducts. AprilAire has been there since the beginning by introducing the first whole-home humidifier in 1954.
