Aerostar 19.875 x 21.50 x 0.75 in MERV 11 Pleated Air Filter, 6-Pack — Made in USA

Overview

Upgrade your HVAC filtration with the Aerostar MERV 11 pleated air filter. Packaged as a 6 pack, the filters come in the actual size of 19.875 x 21.50 x 0.75 inches and are designed for standard 1 inch filter slots, making installation straightforward for many compatible systems.

These filters use electrostatically charged synthetic media to attract particles from the air, including dust, pollen, mold spores, pet dander, and smoke. A portion of these particles is trapped before they can circulate back into living spaces, supporting a cleaner air experience without changing your routine. The filtration strength is balanced with airflow, helping your HVAC system run efficiently while the pleated design provides a larger surface area for longer lasting performance.
