This genuine AprilAire replacement water panel / humidifier filter is the backbone of your AprilAire whole-house humidifier. The heavy-duty aluminum mesh frame holds its shape over the life of the water panel humidifier filter as the porous ceramic-type coating 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 humidifier filter. The humidified air is carried through the house through the air ducts.
