Step up to premium filtration with the 20x20x1 MERV 13 Air Filter Pro. Beyond dust, pollen, and pet dander, its denser media captures wildfire smoke, smog, fine soot, and bacteria-carrying droplets that MERV 8 filters miss — ideal for allergy sufferers and smoke-prone areas. Keeps airflow efficient and lasts ~90 days. Single unit or case pack.
