3M 7100188258 Pleated Air Filter Merv 11 20x20x1 Inches

Product Description

The 3M 7100188258 is a pleated electrostatic air filter rated MERV 11 with 88% particle capture efficiency. It is designed for forced-air HVAC systems where improved indoor air quality is a priority without sacrificing airflow. The filter uses a polypropylene media construction and includes an integrated frame for secure seating in standard filter slots. At a nominal size of 20 x 20 x 1 inches, it fits a wide range of residential and light commercial air handlers and furnaces. MERV 11 filtration captures fine dust, pollen, mold spores, pet dander, and fine particulate matter. HVAC technicians and facilities maintenance personnel routinely specify this filter for scheduled PM programs.

This filter is suited for residential and light commercial forced-air systems including gas furnaces, heat pumps, and central air handlers that accept a 20 x 20 x 1 inch filter. The MERV 11 rating makes it appropriate for environments where occupants have allergies or where air quality standards are elevated above baseline. The electrostatic polypropylene media holds its capture efficiency throughout the service cycle without requiring washing or recharging.
