Why it matters
The Aprilaire 4837 Humidifier Maintenance Kit is a replacement water panel for a whole-house furnace humidifier.
The listing names what it fits: Whole-House Humidifier Models 560, 560A, 568. Match the model number on your humidifier, or the number printed on the old pad, before ordering.
A maintenance kit bundles the water panel with the small parts that wear alongside it, typically the distribution tray or feed tube and the orifice, so one annual order covers the service.
Hard water leaves scale that stops a pad wicking; replace it when it stiffens or crusts, and at least once a season.
