Bsc Preferred 9803-4 Air Filter 20x25x1 Mpr 1000

Product Description

The BSC PREFERRED 9803-4 is a 20 x 25 x 1 inch electrostatically charged pleated air filter rated at MPR 1000. It is designed for residential and light-commercial forced-air HVAC systems as a drop-in replacement filter in standard 1-inch filter tracks. The electrostatically charged media captures large allergens including mold spores and pet dander at approximately 90% efficiency, while also targeting microscopic particles such as dust, smoke, and smog. The filter media is also rated to capture bacteria-carrying particles that can transport viruses. Typical service life is up to 3 months under normal residential operating conditions. HVAC technicians and facilities maintenance personnel are the primary installers.

This filter fits standard 1-inch filter slots in residential and light-commercial forced-air furnaces, air handlers, and central air conditioning systems. It is suited for environments where occupant health is a concern, including homes with pets, allergy sufferers, or occupants with respiratory sensitivities. The filter meets the guidelines of the American Lung Association Health House Program, making it a suitable choice for installs where indoor air quality documentation may be required. It is sold individually and ordered in minimum quantities suitable for bulk stocking.
