3M 7100188250 Pleated Air Filter 20x25x1 Merv 11 88%

Product Description

The 3M 7100188250 is a pleated electrostatic air filter designed for forced-air HVAC systems in residential and light commercial applications. Rated MERV 11 with 88% particle capture efficiency, it captures a broad range of airborne particulates including dust, pollen, mold spores, and fine debris. The filter uses a polypropylene electrostatic media that generates a static charge to attract and hold particles as air passes through. An integrated frame keeps the media securely seated in the filter slot. Nominal dimensions are 20 x 25 x 1 inches, making it a common size for standard residential air handlers and furnaces. HVAC technicians and experienced DIYers install this filter during routine maintenance cycles.

This filter fits standard 20 x 25 x 1 inch filter slots found in residential gas furnaces, heat pumps, and central air handlers. It is suited for environments where improved indoor air quality is a priority — such as homes with pets, occupants with allergies, or high-dust work environments. The MERV 11 rating makes it appropriate for residential systems that can handle moderate static pressure drop without airflow restriction issues. Actual dimensions are 19.69 x 24.69 x 0.84 inches to allow for standard slot fit.

Compatibility

Designed as an OEM-style replacement filter for residential and light commercial forced-air HVAC systems with a standard 20 x 25 x 1 inch filter slot.

Installation Notes

HVAC technicians or qualified DIYers should power down the air handler or furnace before replacing the filter. Verify airflow direction arrows on the filter frame align with system airflow before seating the filter. Filters should be replaced on a schedule appropriate to system usage and indoor air quality conditions — MERV 11 filters typically require more frequent replacement in high-dust environments than lower-rated filters. Inspect the filter slot for bypass gaps and ensure the integrated frame seats flush against the housing.
