AF20x23x1-M13 Merv 13 Air Filter 20x23x1

Product Description

The AF20x23x1-M13 is a MERV 13 pleated air filter designed for residential and light commercial HVAC systems. It captures airborne particles including dust, pollen, mold spores, fine dust, smoke, and fine particulate matter at a MERV 13 efficiency level. The nominal size is 20 x 23 x 1 inches, with an actual size of 19.5 x 22.5 x 0.75 inches. Licensed HVAC technicians and experienced DIYers install this filter in forced-air systems during routine maintenance intervals. The pleated media construction increases surface area for improved particle capture without excessive pressure drop across the filter rack.

This filter fits into standard 1-inch filter slots in residential and light commercial air handlers, furnaces, and fan coil units. It is suited for systems where MERV 13 filtration is specified, including applications that require capture of fine particulate matter for improved indoor air quality. Filters sold in a quantity of 10 per order, making it practical for stocking multiple units for scheduled maintenance cycles.

Installation Notes

HVAC technicians and qualified service personnel should power down the air handler or furnace at the disconnect or thermostat before replacing the filter. Confirm airflow direction arrows on the filter frame are oriented toward the blower, not the return air side. Check the filter rack for any debris or buildup before inserting the new filter. Follow the equipment manufacturer guidelines and local codes for filter replacement intervals, particularly when MERV 13 filtration is specified to avoid excessive static pressure on the system.
