Aprilaire Model 10 Water Panel for your Whole-Home Humidifier

The "heart" of your whole-house humidifier, the Water Panel (also known as humidifier filter, water pad, evaporator pad), should be changed at least once per heating season. The pad is constructed of an expanded aluminum honeycomb mesh that is dipped in a clay coating. This coating is able to absorb and hold water. Warm, dry air is forced through the wet pad to introduce water vapor into the home.

Replacing the humidifier pad / filter

Humidifier water panels are a regular replacement item in whole-house humidifiers. For the best performance we recommend that the Water Panel be replaced once a year, either prior to the start or at the end of the heating season. If you have especially hard water - the panel can be replaced 2 times per year.

Aprilaire pads / filters are designed to be easily replaced in Aprilaire furnace humidifiers. Simply by removing the humidifier cover, the pad / filter can be taken out and a new one slid into place. This can be performed by the homeowner in a matter of minutes. See your humidifier instructions for more information.
