Whether the HC22A1007 and Lennox X2660 humidifier pads interchange.

Same fit group, different frame. The HC22A1007 and Lennox X2660 cover the same humidifiers but differ in size.
Fitment notes

The HC22A1007 and the Lennox X2660 sit in the same GA1 cross-reference group and cover the same humidifier slot, but the HC22A1007 measures 10 in W x 9.5 in H x 1.5 in D while the Lennox X2660 measures 10 in W x 9.75 in H x 1.75 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.
