3M 7100188272 Filtrete Micro Allergen Air Filter 15x20x1

Product Description

The 3M 7100188272 is a 1-inch pleated air filter from the Filtrete Micro Allergen line, designed for residential forced-air HVAC systems. It targets both microscopic particles and larger biological allergens, capturing contaminants such as dust, smoke, smog, mold spores, and pet dander as air passes through the filter media. The 1-inch depth fits standard residential filter slots without modification. Replacement is typically recommended every 3 months under normal operating conditions. HVAC technicians and knowledgeable homeowners install this filter as part of routine preventive maintenance on central air and heating systems.

This filter is suited for residential split systems, heat pumps, and gas furnaces equipped with a standard 1-inch filter cabinet or return-air grille. The 15 inches x 20 inches x 1 inch nominal size covers a common residential return-air opening. It is appropriate for single-family homes, condominiums, and light-commercial spaces where improved particulate capture over a standard fiberglass filter is desired.

Installation Notes

Installation is performed by HVAC technicians or qualified homeowners. Set the system thermostat to the off position before removing the existing filter to prevent unfiltered air from circulating during the swap. Confirm airflow direction arrows on the filter frame align with the direction of airflow toward the blower. Dispose of the used filter in a sealed bag to contain captured particulates.
