AF21x22x1-M8 Merv 8 Air Filter 21x22x1

Product Description

The AF21x22x1-M8 is a MERV 8 pleated air filter designed for residential and light commercial HVAC systems. Rated at MERV 8, it captures a broad range of airborne particles including dust, pollen, mold spores, and lint, making it a solid baseline filter for forced-air heating and cooling applications. The nominal size is 21x22x1 inches, with an actual size of 20.5x21.5x0.75 inches. This listing covers a quantity of 10 filters. Installation is straightforward and does not require tools, making this a routine service item for HVAC technicians and facilities maintenance staff.

This filter fits standard 1-inch filter tracks in residential forced-air furnaces, air handlers, and central air conditioning systems where a 21x22x1 nominal slot is specified. MERV 8 filtration is commonly specified in residential applications where improved particulate capture is needed without significantly restricting airflow. The pleated media design increases surface area compared to fiberglass panel filters, supporting longer service intervals between replacements.

Installation Notes

Filter replacement is a routine maintenance task performed by HVAC technicians or qualified maintenance personnel. Always set the thermostat to off and shut down the air handler or furnace at the disconnect before removing the existing filter. Install the new filter with the airflow arrow on the frame pointing toward the blower. Follow equipment manufacturer recommendations for replacement intervals, typically every 30 to 90 days depending on occupancy and air quality conditions.
