AprilAire 45 Water Panel Humidifier Filter Replacement for AprilAire Whole House Humidifier Models 400, 400A, 400M (Pack of 2)
Maintaining proper humidity levels is integral to maintaining Healthy Air. This genuine AprilAire replacement water panel humidifier filter is made with heavy-duty paper reinforced with two layers of aluminum and coated with an anti-microbial agent to prevent the growth of biologicals. 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.
