Field Controls MERV (Minimum Efficiency Reporting Value) pleated media filter contains enough air cleaning capacity to clean air for months without restricting air flow or putting a strain on the air handling system. Our filter media is electrostatically “supercharged” for better efficiency and longer service life. It is moisture resistant and will not support the growth of bacteria or other microbes. Meets ANSI/ASHRAE 52.2 standards.

What is MERV? Minimum Efficiency Reporting Value, commonly known as MERV rating, is a measurement scale designed to represent the expected performance of a filter when dealing with particles in the range of 0.3 to 10 microns. The MERV rating is from 1 to 16. Higher MERV ratings correspond to a greater percentage of particles captured on each pass, with a MERV 16 filter capturing more than 95% of particles over the full range. Field Controls offers Media Air Cleaners with MERV 8, MERV 11, and MERV 13 ratings.
