Filter King AF18x18x2-M8 Merv 8 Air Filter 18x18x2

Product Description

The FILTER KING AF18x18x2-M8 is a MERV 8 pleated air filter designed for residential and light commercial HVAC systems. Rated at MERV 8, this filter captures a broad range of airborne particulates including dust, pollen, mold spores, and pet dander, making it a reliable choice for standard filtration applications. The nominal size is 18x18x2 inches, with an actual size of 17.5x17.5x1.75 inches and a 2-inch depth profile. Installation is straightforward for HVAC technicians and experienced DIYers servicing forced-air heating and cooling systems.

This filter is suited for use in forced-air furnaces, air handlers, and central air conditioning systems that accept a 2-inch filter slot. The 18x18x2 nominal size is a common fit for residential return-air grilles and filter racks. MERV 8 filtration provides a meaningful upgrade over fiberglass panel filters while maintaining adequate airflow for most residential systems. It is appropriate for standard homes and light commercial spaces where balanced filtration and system efficiency are both priorities.

Compatibility

Designed as a direct-fit replacement for residential and light commercial forced-air HVAC systems requiring a nominal 18x18x2 inch filter. Verify the actual filter-slot dimensions before installation to confirm fit with the 17.5x17.5x1.75 inch actual size.

Installation Notes

This filter is typically installed by HVAC technicians or knowledgeable property maintenance personnel. Power down the air handler or furnace at the disconnect or thermostat before replacing the filter. Insert the filter with the airflow arrow on the frame pointing toward the blower and away from the return-air duct. Follow the equipment manufacturer's recommended replacement interval, which for MERV 8 filters in average residential use is typically every 60 to 90 days.
