Aprilaire #35 Water Panel Evaporator, 2-Pack

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. This product serves as a replacement for many brands and models (see list below).
