Filter King AF20x20x5-HW-M8 Merv 8 Air Filter 20x20x5

Product Description

The FILTER KING AF20x20x5-HW-M8 is a MERV 8 pleated air filter designed for whole-house HVAC filtration systems. With a nominal size of 20x20x5 inches and an actual size of 19.68 x 19.93 x 4.37 inches, this filter fits standard whole-house filter housings and media cabinets. The pleated design increases surface area to capture airborne particulates including dust, pollen, mold spores, and lint. MERV 8 filtration is the standard rating for residential and light commercial systems where improved indoor air quality is required without excessive static pressure drop. This filter ships as a pack of 10 units, making it suitable for stocking multiple service calls or scheduled maintenance cycles.

This filter is intended for installation in whole-house media filter cabinets commonly found in residential forced-air heating and cooling systems. The 5-inch depth accommodates standard whole-house filter housings that accept thick media cartridges, offering longer service intervals compared to standard 1-inch filters. MERV 8 performance makes it appropriate for households with moderate air quality needs, capturing particles in the 3 to 10 micron range. HVAC technicians and service contractors often use this filter as a scheduled maintenance replacement during seasonal tune-ups.

Installation Notes

Installation should be performed by a qualified HVAC technician or experienced service professional. Power down the air handler or furnace at the disconnect or breaker before accessing the filter cabinet. Confirm airflow direction arrows on the filter frame match the direction of airflow through the system before closing the cabinet. Filter replacement intervals vary by system load and air quality conditions but are typically every 6 to 12 months for whole-house media filters.
