Whether the GeneralAire 990-13 and Trane BAYPAD02A1310A humidifier pads interchange.

Same fit group, different frame. The GeneralAire 990-13 and Trane BAYPAD02A1310A cover the same humidifiers but differ in size.
Fitment notes

The GeneralAire 990-13 and the Trane BAYPAD02A1310A sit in the same GA35 cross-reference group and cover the same humidifier slot, but the GeneralAire 990-13 measures 9.75 in W x 12 in H x 1.5 in D while the Trane BAYPAD02A1310A 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.
