Replacement Air Filter Cartridge 20" x 20" x 4.3" (MERV 8)

  • California Prop 65


This filter’s Minimum Efficiency Reporting Value (MERV) is specified by ASHRAE Standard 52.2. It is based on lab tests to determine the filter’s ability to trap particles. MERV ratings for residential filters will typically be in the range of MERV 1-13. The higher the value, the more efficient the filter. MERV 8 filters have a minimum of 70% particle collection efficiency in the 3-10 micron particle size range. (Human hair is approximately 50-100 microns in diameter.) All four sizes of filters reach a MERV 8. For enhanced filtration, MERV 11 and MERV 13 options are available.


These filters accommodate between 13 and 25 sq. ft. of filter media into a unique low-pressure drop design providing some of the largest dust-holding capacities available in efficient residential air cleaners today. The exceptionally large surface area traps dust, pollen, molds, tobacco smoke, grease, soot, bacteria, and animal dander to provide cleaner, fresher air, free of airborne pollutants and irritants regardless of season.

For optimum system performance use the FNCCAB & Carrier FILXXFNC high efficiency media filters designed especially for Carrier furnaces.
