Product Description

The 3M 7100188875 is a Filtrete Micro Allergen reduction air filter designed for residential forced-air HVAC systems. Sized at 12 inches x 24 inches x 1 inch, it fits standard 1-inch filter slots in furnaces and air handlers. The filter targets both microscopic and large airborne allergens, including dust, smoke, smog, mold spores, and pet dander. It is rated for a 3-month service interval under typical residential use conditions. HVAC technicians and homeowners install this filter as part of routine preventive maintenance to protect equipment and maintain indoor air quality.

This filter is suited for residential forced-air heating and cooling systems that accept a standard 1-inch disposable filter. It is appropriate for split systems, packaged units, and air handlers installed in homes where allergen reduction is a priority. The 12 inches x 24 inches x 1 inch nominal size covers a common residential duct and filter cabinet dimension. Service professionals stocking filters for residential maintenance accounts will find this size applicable to a wide range of equipment installations.

Installation Notes

Filter replacement is performed by HVAC technicians or qualified service personnel as part of routine preventive maintenance. Always shut down the HVAC system at the thermostat and disconnect power at the disconnect switch or breaker before opening the filter cabinet. Note the airflow direction arrow printed on the filter frame and orient the filter so the arrow points toward the blower. Inspect the filter cabinet gasket or sealing surface for gaps that could allow unfiltered air bypass before closing the panel.
