Filter King AF19x19x1A-M13 Merv 13 Air Filter 10 Pack

Product Description

The FILTER KING AF19x19x1A-M13 is a MERV 13 pleated air filter designed for residential and light commercial HVAC systems. With a nominal size of 19x19x1 inch and an actual depth of 0.75 inches, this filter fits a wide range of forced-air furnaces and air handlers. MERV 13 filtration captures fine particulates including dust, pollen, mold spores, and certain airborne pathogens, making it a solid choice for systems requiring higher indoor air quality performance. Licensed HVAC technicians and experienced DIYers install these filters during routine maintenance intervals.

This filter is suited for residential forced-air systems, multi-family units, and light commercial applications where improved filtration efficiency is needed without excessive static pressure drop. The 19x19x1 nominal size serves a common filter slot found in many return-air grilles and filter-rack assemblies. Sold in a 10-pack, this quantity supports scheduled filter replacement programs or multi-unit service routes. Each unit is constructed with a pleated media design that maximizes surface area for particle capture while maintaining adequate airflow.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified service personnel as part of routine preventive maintenance. Power down the air handler or furnace at the disconnect or thermostat before replacing the filter. Note the airflow direction arrow printed on the filter frame and orient it to match the direction of airflow toward the blower. MERV 13 filters generate higher static pressure than lower-rated filters, so verify that the system blower is rated to handle the additional resistance before installing in older or lower-capacity equipment.
