Filter King AF19x27x1A-M13 Merv 13 Air Filter 19x27x1

Product Description

The FILTER KING AF19x27x1A-M13 is a MERV 13 pleated air filter designed for residential and light commercial HVAC systems. With a nominal size of 19x27x1 inch and an actual size of 19 inches by 27 inches by 0.75 inches, this filter fits standard 1-inch filter slots. MERV 13 filtration captures fine particulates including dust, pollen, mold spores, pet dander, and fine smoke particles. This filter is sold in a pack of 10, making it well suited for service contractors and property managers who stock filters in volume.

This filter is intended for forced-air systems using a 1-inch filter rack or return-air grille sized for nominal 19x27x1 inch filters. Typical applications include residential gas or heat pump systems with central air handlers, as well as light commercial rooftop units with compatible filter compartments. HVAC technicians and facility maintenance staff commonly install this filter during routine preventive maintenance visits.

Installation Notes

Air filter replacement is performed by HVAC technicians and qualified maintenance personnel. Before replacing the filter, set the thermostat to off and shut down the air handler to prevent unfiltered air from bypassing the media during changeout. Install the filter with the airflow arrow on the frame pointing toward the blower, away from the return-air side. Dispose of the used filter in a sealed bag to contain captured particulates.
