Humidifier Water Panels — 2-Pack

The panel your whole-home humidifier runs on — and the one everyone forgets to change. The water panel (evaporator pad) is where your humidifier actually makes moisture. As it loads up with mineral scale over the heating season, output quietly drops: dry air, static shocks, sore throats, and cracking wood — while the humidifier runs like nothing's wrong.

What it saves you: a fresh panel at the start of heating season restores full output. Manufacturers call for replacement once or twice a season; a scaled-over panel also grows what you don't want in the airstream.

Picking your panel: match the number on your old panel or your humidifier's model plate — #35 fits AprilAire 600-series humidifiers, #10 fits 500-series, #45 fits 400-series. Swap takes about five minutes: water off, cover off, old panel out, new panel in.

What's included: 2 water panels in the model you select. Genuine-spec evaporator panels, manufacturer packaging.
