Whether the AprilAire 35 and HC26E1004 humidifier pads interchange.
The Aprilaire 35 and Honeywell HC26E1004 sit in the same cross-reference group and cover the same humidifier fit lists, but the Aprilaire panel measures 13 inches high by 1.75 inches thick while the Honeywell pad is 13.25 inches high by 1.5 inches thick.
The quarter-inch size difference means the HC26E1004 can sit slightly loose in an Aprilaire frame or the Aprilaire 35 can sit slightly proud in a Honeywell frame. Either fits the same humidifiers, but seat it fully so water wicks through the pad rather than running down the frame.

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.
