filters 20X24X2 Merv11
pleated air filters Merv 11 for Nexair5.0 20X24X2.
Use to protect the H.E.P.A Filter.
MERV 11 general purpose pleated air filters provide between 80% and 85% efficiency for filtering particles between 3 and 10 microns in size (such as mold spores, dusting aids, and cement dust). They also provide between 50% and 65% efficiency for filtering particles between 1 and 3 microns in size (such as legionella, lead dust, humidifier dust, coal dust, and nebulizer droplets) and less than 20% efficiency for filtering particles between 0.30 and 1 micron in size (such as bacteria, most smoke, sneeze nuclei, insecticide dust, copier toner, and face powder). They capture contaminants more efficiently than MERV 10 pleated air filters.
