Filter King AF24x24x1-M11 Merv 11 Air Filter 24x24x1

Product Description

The FILTER KING AF24x24x1-M11 is a MERV 11 pleated air filter designed for residential and light commercial HVAC systems. With a nominal size of 24 x 24 x 1 inches and an actual size of 23.5 x 23.5 x 0.75 inches, it fits standard filter slots in forced-air furnaces, air handlers, and central air systems. The MERV 11 rating captures a broad range of airborne particulates, including dust, pollen, mold spores, pet dander, and fine dust particles, making it a solid choice for environments where indoor air quality is a priority without creating excessive static pressure drop on the system.

This filter is suited for residential forced-air HVAC systems and light commercial applications where MERV 11 filtration is specified or recommended. It installs in standard 1-inch filter tracks on furnaces and air handlers. HVAC technicians, property maintenance crews, and service professionals commonly use this filter during routine maintenance intervals or when upgrading filtration from lower MERV-rated media. The nominal 24 x 24 x 1 inch sizing covers a widely used slot dimension found across many residential and small commercial HVAC installations.

Installation Notes

Installation is performed by HVAC technicians or qualified maintenance personnel. Before replacing the filter, set the system thermostat to off and confirm the air handler or furnace blower has stopped. Insert the filter with the airflow direction arrow on the frame pointing toward the blower, not the return air side. Follow local mechanical codes and equipment manufacturer guidelines for recommended filter change intervals, which typically range from 30 to 90 days depending on system use and air quality conditions.
