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.

Match the frame size, not just the part number. Pads in one cross-reference group share a humidifier fit list but can differ by a quarter inch, so a pad that is slightly short or thin can let water run past it. Confirm the printed dimensions before buying a generic.

What to buy

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.
