Fitment notes
The AprilAire 12 fits AprilAire 112, 224, 225, 440, 445, 445A, 448.
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.
Manufacturers recommend replacing the pad once per heating season; a hardened, scaled or crumbling pad cuts humidity output long before it looks worn out.
