Fitment notes

The AprilAire 35 fits AprilAire 350, 360, 560, 560A, 568, 600, 600A, 600M, 700, 700A, 700M, 760, 760A, 768. The most common Aprilaire panel. It carries a paint stripe on one short end that must point up toward the water tray, except in the 350 and 360 where orientation does not matter.

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.
