The Aprilaire 213 fits Aprilaire 1210, 1620, 2210, 2216, 3210, 4200 media air cleaners. The MERV 13 media for the same four-inch Aprilaire 2210 cabinet as the 210. Drop-in identical size; the 213 simply filters finer.
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.
