3M Company 9803-2PK-HDW Micro Allergen Reduction Filter 20x25x1

Product Description

The 3M COMPANY 9803-2PK-HDW is a Filtrete Micro Allergen Reduction Filter designed for residential forced-air HVAC systems. Sold as a 2-pack, each filter measures 20 inches x 25 inches x 1 inch and installs in standard residential air handler or furnace filter slots. The filter uses electrostatically charged media to attract and capture microscopic allergens including dust, smoke, and smog particles, as well as larger allergens such as mold spores and pollen. HVAC technicians and homeowners service these filters during routine maintenance intervals to maintain indoor air quality and system airflow performance.

This filter is rated for residential use only and fits common 20 x 25 x 1 filter openings found in residential furnaces, air handlers, and whole-home HVAC systems. The 2-pack format is suited for stocking multiple units during a single service call or seasonal maintenance visit. It is not rated for commercial or industrial air handling applications.
