AF25x32x1-M11 Merv 11 Air Filter 25x32x1

Product Description

The AF25x32x1-M11 is a MERV 11 pleated air filter designed for residential and light commercial HVAC systems. It captures airborne particulates including dust, pollen, mold spores, pet dander, and fine debris that lower-rated filters pass through. The nominal size is 25x32x1 inches with an actual size of 24.5x31.5x0.75 inches, making it a standard 1-inch media filter. MERV 11 filtration strikes a practical balance between particle capture efficiency and airflow restriction, making it a common choice for systems where air quality matters without sacrificing system pressure drop performance. HVAC technicians and homeowners servicing their own systems install these as part of routine filter change maintenance.

This filter is suited for forced-air heating and cooling systems using a 25x32x1 nominal filter slot. Typical applications include gas furnaces, air handlers, and central air conditioning systems in residential homes and small commercial spaces. It ships in a quantity of 10 filters per order, supporting scheduled maintenance intervals. The MERV 11 rating makes it appropriate for households with pets, mild allergy concerns, or environments with elevated dust levels where a MERV 8 is insufficient but a MERV 13 would over-restrict system airflow.

Installation Notes

Air filters in this size and depth are installed by HVAC technicians or qualified service personnel as part of routine preventive maintenance. Always shut down the air handler or furnace at the thermostat and disconnect power at the disconnect or breaker before removing the old filter. Check the filter slot or grille frame for the required airflow direction arrow and orient the replacement filter accordingly. Follow manufacturer-recommended replacement intervals, typically every 60 to 90 days depending on occupancy and system runtime.
