Whether the AprilAire 35 and Totaline P110-3545 humidifier pads interchange.

Same fit group, different frame. The AprilAire 35 and Totaline P110-3545 cover the same humidifiers but differ in size.
Fitment notes

The AprilAire 35 and the Totaline P110-3545 sit in the same GA35 cross-reference group and cover the same humidifier slot, but the AprilAire 35 measures 10 in W x 13 in H x 1.75 in D while the Totaline P110-3545 measures 10 in W x 13 in H x 1.5 in D.

Because the frame sizes differ slightly, seat the replacement fully against the water tray so water wicks through the pad rather than running down a gap at the edge. Either one fits the same humidifiers, but a pad that sits loose will drip past.

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.
