Product Description

The FILTER KING AF19x20x5-CAR-M11 is a MERV 11 pleated HVAC air filter rated for a nominal size of 19x20x5 inches. The actual dimensions measure 19.06 x 19.81 x 4.25 inches, making it a deep 5-inch style filter suited for high-capacity air handlers and whole-home filtration systems. At MERV 11, this filter captures a wide range of airborne particles including dust, pollen, mold spores, pet dander, and fine lint. It is installed by HVAC technicians and experienced service pros as part of routine maintenance or system upgrades where improved indoor air quality is a priority.

This filter is designed for residential and light commercial forced-air HVAC systems that accept 5-inch deep filter media. The 19x20x5 nominal sizing fits dedicated media cabinet housings commonly found on central air systems and gas furnaces. It ships in a quantity of 10 per order, making it practical for service companies stocking filters for multiple accounts or for extended replacement intervals at a single property.

Installation Notes

Installation of this filter should be performed by a qualified HVAC technician or experienced service professional. Always power down the air handler or furnace at the disconnect or breaker before removing or installing filter media. Confirm airflow direction arrows on the filter frame are aligned with system airflow before seating the filter in the cabinet. Inspect the filter housing gaskets or seals for wear at each service interval to prevent bypass air around the filter media.
