Filter King AF20x20x1-CO Carbon Hvac Air Filter 20x20x1

Product Description

The FILTER KING AF20x20x1-CO is a carbon pleated HVAC air filter designed for residential and light commercial air handling systems. The activated carbon media works alongside the pleated filter material to capture airborne particulates while also addressing common household odors and volatile compounds that standard pleated filters do not target. With a nominal size of 20x20x1 and an actual size of 19.5 x 19.5 x 0.75 inches, this filter fits standard 1-inch filter slots in furnaces, air handlers, and return-air grilles. HVAC technicians and homeowners familiar with filter replacement will find this a direct-fit option where odor control is a service priority.

This filter is suited for residential forced-air systems and light commercial applications where a 20x20x1 nominal slot is present. It is a practical choice in kitchens, pet households, and environments where odor reduction alongside particulate filtration is desirable. The carbon-infused pleated construction provides a larger surface area than flat-panel filters, supporting reasonable airflow while capturing dust, lint, and airborne odors. Filters are sold in a quantity of 10 per order, making this well-suited for maintenance accounts or multi-unit service schedules.

Installation Notes

Air filter replacement is performed by HVAC technicians and qualified building maintenance personnel. Always shut down the air handling system at the thermostat and disconnect power at the unit or disconnect switch before opening the filter compartment. Confirm the airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Inspect the filter housing gaskets and frame for gaps that could allow bypass; an airtight fit is essential for proper filtration performance.
