AprilAire L HydroCore™ Water Panel Cartridge for 720 Humidifiers

This replacement evaporator pad is also called a "filter" or "water panel". The water panel captures water as hot, dry air from your furnace blows across it, providing comfortable, humid air to your home. The panel is constructed of an expanded aluminum honeycomb mesh, which is dipped in a clay coating. The all-in-one L HydroCore for the AprilAire 720 Humidifier is user-friendly, popping in and out for easy maintenance and including everything needed to replace the humidifier water panel, pre-assembled and ready to use. Emphasizing superior sustainability, the HydroCore frame is recyclable and made with recycled plastic.
