Filter King AF14x20x1-M13 Merv 13 Air Filter 14x20x1

Product Description

The FILTER KING AF14x20x1-M13 is a MERV 13 pleated air filter designed for residential and light commercial HVAC systems. With a nominal size of 14x20x1 inches and an actual size of 13.5 x 19.5 x 0.75 inches, this filter fits standard 1-inch filter slots found in forced-air furnaces, air handlers, and central air conditioning systems. Rated at MERV 13, it captures fine particulates including dust, pollen, mold spores, pet dander, and fine aerosols, making it a solid choice for occupants with air-quality concerns. Sold in a 10-pack, this filter is a practical bulk option for maintenance programs and multi-unit service routes.

This filter is suited for residential single-family homes, apartments, and light commercial spaces where a MERV 13 rating is specified. It installs in standard return-air grilles, furnace filter racks, and air handler cabinets that accept 1-inch filters with a 14x20-inch nominal footprint. Service technicians stocking multiple accounts will find the 10-pack format convenient for scheduled filter replacements during routine maintenance visits.

Installation Notes

Filter installation and replacement is typically performed by HVAC technicians or qualified maintenance personnel. Before replacing the filter, set the thermostat to the off position and shut down the air handler or furnace to prevent unfiltered air from bypassing the rack during the swap. Verify airflow direction arrows on the filter frame align with the direction of airflow toward the blower. Dispose of spent filters per local waste guidelines, as MERV 13 media may carry captured biological particulates.
