The correct filter size and OEM part for the Honeywell F100 / F200 20x25.

Fitment notes

The 20-wide Honeywell F100 and F200 cabinets, and Space-Gard 2200, take a 20 by 25 by 4 filter, the FC100A1037.

Order by the nominal size 20 x 25 x 4 inches. The Honeywell FC100A1037 is the OEM media; a generic of the same nominal size and depth in the MERV you want will also seat in the cabinet.
