Product Description

The 3M 7100188271 is a Filtrete Micro Allergen replacement air filter designed for residential forced-air HVAC systems. Sized at 10 inches x 20 inches x 1 inch, it fits standard 1-inch filter slots in furnaces and air handlers. The filter captures microscopic airborne particles including dust, smoke, and smog, as well as larger allergens such as mold spores and pet dander. It is rated for approximately 3 months of service under typical residential use. HVAC technicians and homeowners install this filter as part of routine preventive maintenance to maintain indoor air quality and protect system components from particulate buildup.

This filter is suited for residential forced-air heating and cooling systems with a 10-inch x 20-inch x 1-inch filter slot. Typical applications include gas furnaces, heat pumps, and central air conditioning systems equipped with standard 1-inch media filter racks or built-in filter compartments. It is well-suited for households with occupants sensitive to airborne allergens, dust, or smoke. The 6-pack quantity reduces service call frequency for property managers and multi-unit operators maintaining several systems on a recurring filter-change schedule.
