The Aprilaire 45 Water Panel is a humidifier pad made of paper with metal support. The paper absorbs and holds water flowing through the pad, allowing warm air flowing across the pad to evaporate the water and humidify the air. This pad is used in drainless units — the paper pad also wicks water back up from the bottom reservoir.
Minerals contained in the water are left on the pad as the water evaporates, clogging the pad and restricting both water and air flow. For this reason the pad should be changed twice per heating season. If you have hard water with higher mineral content, you may need to change the pad more frequently. Cleaning the pad is not possible.
A Water Panel may also be referred to as a humidifier pad, evaporator pad or Vapor Pad.
This pad fits into a reusable plastic frame.
Sold as a package of 2 pads, typically good for one heating season.
