3M 7100203129 Pleated Air Filter 20x25x1 Merv 12

Product Description

The 3M 7100203129 is a pleated electrostatic air filter designed for residential and light-commercial HVAC systems requiring a 20 x 25 x 1 inch filter slot. Rated MERV 12 with 90% particle capture efficiency, this filter uses an electrostatically charged polypropylene media to capture fine airborne particles including dust, pollen, mold spores, and fine debris. It ships as an individual filter unit. HVAC technicians and facilities maintenance staff install this filter during routine preventive maintenance cycles. The integrated frame maintains structural integrity under normal airflow conditions and simplifies drop-in replacement.

This filter is suited for forced-air residential and light-commercial systems that call for a nominal 20 x 25 x 1 inch filter. The MERV 12 rating makes it appropriate for environments where improved indoor air quality is a priority, such as homes with allergy concerns or commercial spaces requiring better-than-standard particulate control. It installs in standard filter racks, return-air grilles, and air handler filter sections designed for 1-inch media. The polypropylene electrostatic media does not require a separate charging source — the material carries a permanent electrostatic charge.

Key Features

• MERV 12 rating with 90% particle capture efficiency
• Electrostatically charged polypropylene media for enhanced particle attraction
• Nominal 20 x 25 x 1 inch size fits standard filter racks and return-air grilles
• Actual dimensions: 24.69 x 19.69 x 0.81 inches for precise fitment reference
• Integrated rigid frame supports media structure and simplifies installation
• Lightweight at 0.74 pounds for easy single-technician handling

Compatibility

Designed as a drop-in replacement for any forced-air HVAC system accepting a nominal 20 x 25 x 1 inch pleated air filter with a 1-inch media slot.

Installation Notes

Installation is performed by HVAC technicians or qualified maintenance personnel. Power down the air handler or furnace at the disconnect or breaker before replacing the filter. Confirm airflow direction arrows on the filter frame align with system airflow toward the blower. Inspect the filter rack and sealing surfaces for gaps that would allow air bypass, which significantly reduces filtration efficiency at any MERV rating.
