The 3M COMPANY 9800-2PK-HDW is a Micro Allergen Reduction Filter designed for residential forced-air HVAC systems. Sized at 16 inches x 20 inches x 1 inch, it fits standard residential return-air filter slots and comes as a two-pack. The filter attracts and captures microscopic allergens including dust, smoke, and smog particles, along with larger allergens such as mold spores and pollen. Licensed HVAC technicians and knowledgeable homeowners install these as routine maintenance filters in residential furnaces and air handlers.
This filter is rated for residential use only and is intended for standard 1-inch filter tracks in forced-air heating and cooling systems. The two-pack format supports back-to-back filter change cycles without the need for an additional order. Compatible with any residential furnace, air handler, or HVAC system that accepts a 16 inches x 20 inches x 1 inch filter.
Designed for residential forced-air furnaces, air handlers, and HVAC systems that accept a 16 inches x 20 inches x 1 inch filter. For residential use only.
Filter installation is performed by HVAC technicians or qualified homeowners as part of routine system maintenance. Always power down the furnace or air handler at the thermostat and disconnect power at the breaker before opening the filter compartment. Insert the filter with the airflow arrow pointing toward the blower, not toward the return-air duct. Follow local codes and manufacturer guidelines for recommended filter change intervals.
