Whether the AprilAire 35 and Lennox X2661 humidifier pads interchange.
The AprilAire 35 and the Lennox X2661 are in the same GA35 cross-reference group and share the same published size, 10 in W x 13 in H x 1.75 in D. A humidifier that takes one takes the other.
They are the same size, so the only real difference is brand and, on some pads, an antimicrobial coating. Buy whichever is cheaper for your unit and replace it once a season.
