3M NADP03-2IN-4 Filtrete Air Filter 1000 Mpr 20x25x2 4-pack

Product Description

The 3M COMPANY NADP03-2IN-4 is a Filtrete Allergen Defense air filter rated at 1000 MPR (Microparticle Performance Rating), sold as a 4-pack. Each filter measures 20 inches x 25 inches x 2 inches and is designed to capture airborne allergens including pollen, mold spores, and dust mite debris from residential forced-air HVAC systems. The 1000 MPR rating positions this filter between standard fiberglass media and high-efficiency MERV-rated hospital-grade units, making it a practical choice for residential systems where occupant allergy concerns are a priority without over-restricting airflow.

This filter is suited for residential split systems, heat pumps, and gas or electric forced-air furnaces that accept a 20 x 25 x 2-inch filter size. The 4-pack format supports a full year of seasonal filter changes at the recommended 3-month replacement interval. HVAC service technicians often specify this filter for residential maintenance agreements where allergen reduction is part of the service scope.

Compatibility

Installation Notes

Installation should be performed by a qualified HVAC technician or informed homeowner. Set the system thermostat to the off position and shut down the air handler before removing the existing filter. Insert the new filter with the airflow arrow on the frame pointing toward the blower, not toward the return duct. Dispose of the used filter in a sealed bag to contain captured particulates.
