Description
Product Overview
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. MERVs 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.

Large Dust Holding Capacity— 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 that is free of airborne pollutants and irritants regardless of the season.
