How to find the right Honeywell filter
The part number is printed on the filter frame. In the FC100A and FC200E ranges the last four digits give the size: 1003 is 16x20, 1011 is 20x20, 1029 is 16x25 and 1037 is 20x25, all 4 inches deep. Moving from FC100A to FC200E keeps the same size and raises the rating from MERV 11 to MERV 13.
