Honeywell F100 20x25 media cabinets commonly use FC100A1037 filters. Cabinet size is the key signal.

Before choosing replacement filters
  • Match the device label to F100 20x25; series names alone can point to another part.
  • Compare the old part number against each confirmed fit before ordering.
  • Use the fit note when depth, cartridge stage, bag type, or kit contents are unclear.
