Fitment notes

The Honeywell FC100A1037 fits Honeywell F100 and F200 20x25 media air cleaners and Space-Gard 2200. The 20 by 25 by 4 MERV 11 media for the wider Honeywell F100 cabinet. It fits the same four-inch class as the Aprilaire 210, not the six-inch Aprilaire 2200 filter.

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.
