Replacement Air Filter Cartridge 24" x 25" 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. MERV 11 filters have a minimum of 85% particle collection efficiency in the 3-10 micron particle size range and 65% - 80% particle collection efficiency in the 1-3 micron particle size range. (Human hair is approximately 50-100 microns in diameter.) All three sizes of filters are offered in MERV 8 and MERV 11.


These filters can accommodate between 22 and 28 sq. ft. (2 and 3 sq. meter) of filter media into a unique low-pressure drop design providing one 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 that is free of airborne pollutants and irritants regardless of the season.

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