The 3M 7100188885 is a Filtrete Ultra Allergen Reduction air filter designed for residential forced-air HVAC systems. Measuring 16 inches x 20 inches x 1 inch, this filter uses electrostatically charged media to attract and capture microscopic airborne particles including bacteria and particles that can carry viruses, as well as larger particles such as mold spores and pollen. It is a standard one-inch depth filter suited for residential furnaces and air handlers with a matching filter slot. HVAC technicians and homeowners servicing residential systems install this filter as part of routine maintenance.
This filter is rated for residential use only and fits into standard 16 x 20 x 1 filter housings found in typical residential gas or electric furnace systems and central air handlers. It is sold individually (UOM: Each) with a minimum order quantity of 4 units. The filter targets common indoor air quality concerns by capturing allergens, making it appropriate for residential installations where air quality improvement is a priority alongside equipment protection.
Designed as an OEM-style replacement filter for residential forced-air furnace and air handler systems requiring a standard 16 inches x 20 inches x 1 inch filter.
Filter replacement is a routine maintenance task performed by licensed HVAC technicians or qualified homeowners. Always set the system thermostat to the off position and shut down the air handler or furnace before opening the filter access panel. Note the airflow direction arrow printed on the filter frame and orient the filter so the arrow points toward the blower. Replace filters on a schedule appropriate to household conditions and system runtime to maintain airflow and filtration performance.
