The Aprilaire 401 fits Aprilaire 2400 and Space-Gard 2400 media air cleaners. The six-inch media for the 16-wide Aprilaire 2400 cabinet. It is the 16 by 25 counterpart of the 201, not interchangeable with it because the 201 is 20 wide.
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.
