The Aprilaire 413 fits Aprilaire 1410, 1610, 2410, 2416, 3410, 4400 media air cleaners. The MERV 13 media for the four-inch 16-wide Aprilaire 2410 cabinet. Home Depot also lists it as FPR 12 plus. It is the 16 by 25 counterpart of the 213.
Because a media cabinet seals on the filter frame, match the actual depth, not just the nominal width and height. A filter of the right face size but the wrong depth will let air slip around it.
