The FILTER KING AF20x24x1-M13 is a MERV 13 pleated air filter designed for residential and light commercial HVAC systems. With a nominal size of 20x24x1 inches and an actual size of 19.5 x 23.5 x 0.75 inches, this filter fits standard 1-inch filter slots. At MERV 13, it captures fine particulates including dust, pollen, mold spores, pet dander, and certain smoke and smog particles. This rating makes it a strong choice for systems where air quality is a priority without significantly restricting airflow in properly sized equipment. HVAC technicians and facilities personnel typically specify MERV 13 filters in systems engineered to handle the associated pressure drop.
This filter is suited for forced-air furnaces, air handlers, and central AC systems with a standard 1-inch filter slot measuring 20x24 inches nominal. It ships in a quantity of 10 per order, making it practical for service contractors stocking replacement filters across multiple residential or small commercial accounts. Typical applications include single-family homes, multi-unit residential buildings, and light commercial spaces where improved filtration is specified.
Designed as an OEM-style replacement pleated air filter for residential and light commercial forced-air HVAC systems with a nominal 20x24x1-inch filter slot. Verify actual filter slot dimensions against the actual size of 19.5 x 23.5 x 0.75 inches before installation.
Air filters in forced-air systems should be replaced by a qualified HVAC technician or trained service professional. Power down the air handler or furnace before removing and replacing the filter. Install with the airflow arrow on the filter frame pointing toward the blower and away from the return air duct. Confirm that the installed MERV 13 rating is compatible with the system fan capacity, as higher MERV ratings can increase static pressure and reduce airflow in undersized equipment.
