Rigid Box Filters

Designed for medium to high efficiency applications, rigid box filters excel in variable volume situations. Offering long service life and consistent performance, box filters are available in several configurations to fit your application. Rigid box filters come in 6” and 12” depths and efficiencies from MERV 11 to MERV 15 (45% to 95% efficiency) based on the ASHRAE 52.2 test standard.
