Whether the AprilAire 10 and GeneralAire GA10 humidifier pads interchange.
The AprilAire 10 and the GeneralAire GA10 sit in the same GA1 cross-reference group and cover the same humidifier slot, but the AprilAire 10 measures 9.75 in W x 10 in H x 1.75 in D while the GeneralAire GA10 measures 10 in W x 9.5 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.

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.
