With a range of efficiency ratings from MERV 11 to MERV 16, KOCH DuraMAX filters are a smart and safe upgrade from bag filters and other box-style rigid filters and effectively help lower the spread of COVID-19 indoors.
Tested in accordance with ASHRAE Test Standard 52.2-2017, DuraMAX is an ideal choice in filtration systems with high velocities or variable air volumes. The high-capacity mini-pleat design allows a nominal 24x24x12 filter to incorporate 194 square feet of filter space, which creates an extremely high dust-holding capacity to significantly prolong the service life of the filter.
