The correct replacement pad for the AprilAire 440 / 445 / 448 / 224, and the sizes that look right but are not.

Fitment notes
The larger-capacity 440, 445 and 448 units and the 224 take the tall Aprilaire 12 panel, not the 35.
The tall panel for the larger-capacity 440 and 445 units. At 14.75 inches high it is the biggest of the Aprilaire panels and does not substitute for a 35 or a 10.
