The wide pad for the GeneralAire 1099 Legacy humidifier only. GeneralAire also catalogs it as part number 7047; it does not cross to the Aprilaire or Honeywell pads.
Manufacturers recommend replacing the pad once per heating season; a hardened, scaled or crumbling pad cuts humidity output long before it looks worn out.
