This 4-3/8″ pleated air filter improves filtration and service life over 1″ filters. MERV 13 rating means the filter captures more than 90% of particles like pollen, dust, lint, dust mites, pet dander & mold spores. Replaces Honeywell models FC100A1037 and FC200E1037. Replace every 6-9 months under normal use.
