Filter King AF19x23x1A-M11 Merv 11 Air Filter 19x23x1

Product Description

The FILTER KING AF19x23x1A-M11 is a MERV 11 pleated HVAC air filter designed for residential and light commercial forced-air systems. With a nominal size of 19x23x1 inch and an actual size of 19x23x0.75 inches, this filter fits standard 1-inch filter slots in air handlers, furnaces, and fan coil units. MERV 11 filtration captures a broad range of airborne particles including dust, pollen, mold spores, pet dander, and fine dust from household activities. Sold in a pack of 10, this filter is a practical stocking choice for service contractors and property managers who perform routine filter changes on multiple units.

This filter is suited for residential forced-air furnaces, central air conditioning systems, and air handlers where a 1-inch filter rack or return-air grille with a nominal 19x23x1 inch opening is present. The MERV 11 rating makes it appropriate for households with pets or mild allergy concerns, or for light commercial applications requiring moderate particulate capture without excessive static pressure drop. It is installed by HVAC technicians and knowledgeable homeowners during routine preventive maintenance.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified service professional. Power down or set the thermostat to the off position before replacing the filter to prevent unfiltered air from being drawn through the system during the changeover. Confirm the airflow direction arrow on the filter frame is oriented toward the blower before securing the filter in the rack. Follow equipment manufacturer guidelines and local codes for recommended filter change intervals.
