3 Pack GRAINGER 6B593 MIRV 14 20x20x4 Mini-Pleat Air Filter (Box Of 3)
New – Open Box MERV 14 minipleat air filters capture 90% to 95% of particles between 3 and 10 microns in size (such as dusting aids and cement dust), 85% to 90% of particles between 1 and 3 microns in size (lead dust, humidifier dust, coal dust, and nebulizer droplets) and 50% to 75% of particles between 0.30 and 1 micron in size (most smoke, sneeze nuclei, insecticide dust, copier toner, and face powder). They capture contaminants more efficiently than MERV 13 minipleat air filters.
