3M Company S-2003-4 Smart Air Filter 20x25x1 Mpr 1500

Product Description

The 3M COMPANY S-2003-4 is a 20 x 25 x 1 inch electrostatic air filter rated at MPR 1500, sold in a 4-pack. It is engineered to attract and capture microscopic airborne particles including bacteria, particles that can carry viruses, mold spores, and pollen. An integrated sensor pairs with the Filtrete app to monitor actual airflow and filter usage rather than relying on a fixed time interval, signaling when a filter change is warranted based on real conditions. This filter is installed in residential forced-air HVAC systems by HVAC technicians or knowledgeable homeowners during routine maintenance.

This filter is suited for residential forced-air heating and cooling systems that accept a 20 x 25 x 1 inch filter. The MPR 1500 rating places it in the allergen and fine-particle capture tier, making it appropriate for households with occupants sensitive to airborne allergens, bacteria, or virus-carrying particles. The smart sensor functionality requires a compatible mobile device and the Filtrete app. Each package contains 4 filters, reducing the frequency of reorder for standard annual or semi-annual replacement programs.

Installation Notes

Installation is performed by a qualified HVAC technician or a knowledgeable homeowner. Power down or set the thermostat to the off position before opening the filter compartment to prevent unfiltered air from circulating during the change. Verify the airflow direction arrow on the filter frame aligns with the direction of airflow into the air handler or furnace before seating the filter. Pair the sensor with the Filtrete app following the manufacturer setup instructions after installation.
