You can find the part number or the size on the side of the filter. Filters are measured by Nominal size which is a rounded number that varies by brand so many filters have the part number for each brand they are compatible with listed. The Lennox filter below shows it Part number X0583 and the Honeywell part numbers, FC100A1029 and FC35A1001, that this filter can replace.
