Air Handler Pocket Air Filter, 24x24x18, MERV 11, Orange, Synthetic, Number of Pockets: 6

MERV 11 pocket 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 8 pocket air filters.

Pocket air filters are often installed in HVAC systems in auto shops, data centers, food and beverage plants, industrial sites, and schools to trap contaminants in the air stream and boost indoor air quality. They also keep the contaminants from building up in the equipment and damaging it. These filters are best suited for applications where air is constantly flowing through the filter since they may deposit some captured material back into the air stream when they deflate. Also called bag filters, pocket filters have a bag-like filter element that is stitched into pockets. They trap more particles than non-pleated panel filters and need to be changed less often. These filters have a MERV (minimum efficiency reporting value) rating of 8 to 14. A filter's MERV rating measures how efficiently a filter traps contaminants in the air stream based on the size of the particles it can effectively capture. The higher a filter's MERV rating is, the more effectively it traps small particles.
