Mini-Pleat Air Filter, 16x25x2, MERV 11 Model 33E959 6 Pack

Description

6 Pack of MERV 11 minipleat 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).
Minipleat air filters have tightly pleated filter media that traps particles with high efficiency. They are lighter and hold more dust than rigid cell or cartridge air filters, and their rigid frame can withstand difficult operating conditions such as variable air volume, turbulent airflow, and high humidity. Minipleat filters are commonly installed in HVAC systems in offices, hospitals, museums, electronics manufacturing, and similar settings to remove contaminants from the air stream and increase indoor air quality. They also stop contaminants from building up in the equipment and damaging it. These filters have a MERV (minimum efficiency reporting value) rating of 11 to 14. A filter's MERV rating measures how efficiently it removes contaminants from 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 the filter traps small particles.
