700-4 Air Filter, 20 In L, 16 In W, 8 Merv, 700 Mpr, Fiberglass Frame

An electrostatically charged pleated air filter designed to capture and trap dust, pollen, pet dander, and other airborne particles from your home's heating and cooling system. Unlike ordinary fiberglass or non-electrostatic filters, this Filtrete filter uses an exclusive 3-in-1 technology from 3M to attract more microparticles while allowing cleaner air to flow freely through your HVAC system. With each cycle through the filter, your indoor air becomes progressively cleaner, supporting better air quality throughout your home.

A clogged or dirty filter reduces airflow, forcing your heating and cooling system to work harder and consume more energy. Regular filter replacement ensures your system operates efficiently, maintains consistent comfort, and reduces strain on your equipment. This 16x20x1 in. filter is sized for standard residential furnaces, air conditioners, and HVAC systems and is rated for replacement every 90 days for optimal performance.
