Fitment notes

The AprilAire 10 fits AprilAire 110, 220, 500, 500A, 500M, 550, 550A, 558.

The panel for the 500 and 550 bypass humidifiers. It is close in size to the 35 but 3 inches shorter, so the two are not interchangeable even though both are Aprilaire.

Manufacturers recommend replacing the pad once per heating season; a hardened, scaled or crumbling pad cuts humidity output long before it looks worn out.

Read the number stamped on the humidifier cabinet or printed on the old pad, then match it below. Confirm the frame size before buying a generic.
