3M NADP01-2IN-4 Filtrete Air Filter 1000 Mpr 16x25x2

Product Description

The 3M COMPANY NADP01-2IN-4 is a Filtrete Allergen Defense pleated air filter rated at 1000 MPR (Microparticle Performance Rating). It measures 16 inches by 25 inches by 2 inches and ships as a 4-pack. This filter is designed for forced-air HVAC systems, capturing airborne allergens, dust, pollen, and pet dander while maintaining adequate airflow through residential air handlers and furnaces. Licensed HVAC technicians and knowledgeable homeowners typically handle replacement during routine preventive maintenance cycles.

This filter fits standard 16 by 25 by 2 inch filter slots in residential gas furnaces, heat pumps, and split-system air handlers. The 1000 MPR rating places it in the mid-range category, balancing allergen capture efficiency with acceptable static pressure drop across the filter media. It is well-suited for households with allergy concerns where a higher filtration level than a standard fiberglass panel filter is required without the added resistance of a high-MERV media filter.

Key Features

• 1000 MPR filtration rating for enhanced allergen and particulate capture
• 16 x 25 x 2 inch nominal size fits a wide range of residential HVAC filter slots
• Pleated media design increases surface area for improved filtration efficiency

Compatibility

Designed as an OEM-style replacement for residential forced-air HVAC systems requiring a 16 by 25 by 2 inch filter with a nominal 1000 MPR rating.

Installation Notes

Installation is performed by an HVAC technician or qualified service professional. Before replacing the filter, shut down the air handler or furnace at the thermostat and disconnect power at the unit disconnect or breaker. Note the airflow direction arrow printed on the filter frame and align it toward the blower. Verify the measured slot dimensions match the 16 by 25 by 2 inch nominal size before installing to ensure a proper seal and prevent air bypass.
