Filter King AF20X20X5-HW-CO Carbon Air Filter 20x20x5

Product Description

The FILTER KING AF20X20X5-HW-CO is a carbon pleated HVAC air filter designed for residential and light commercial forced-air systems. The activated carbon media targets odors and gaseous contaminants in addition to particulate capture, making it a practical choice where air quality complaints go beyond standard dust and allergen concerns. The nominal size is 20x20x5 inches with an actual size of 19.68 x 19.93 x 4.37 inches, fitting deep-media filter housings that accept 5-inch thick cartridges. HVAC technicians and service pros install this filter in air handlers, furnaces, and whole-house filtration cabinets as part of routine maintenance or air quality upgrades.

This filter is suited for residential and light commercial forced-air applications where a 5-inch deep-media housing is already installed. The extended surface area of the pleated media supports longer service intervals compared to standard 1-inch filters, reducing maintenance frequency in occupied spaces. It is appropriate for systems where odor control from cooking, pets, or volatile compounds is a priority alongside particulate filtration. Units are sold in a case quantity of 10 filters.

Installation Notes

Installation should be performed by a qualified HVAC technician or trained service professional. Power down the air handler or furnace at the disconnect before removing the existing filter and inserting the replacement. Observe the airflow direction arrow printed on the filter frame and align it with the direction of airflow through the system. Dispose of the used filter in accordance with local regulations, particularly when the spent carbon media has captured chemical contaminants.
