Allergy & Pet

Allergy & Pet filters are pleated, electrostatically charged MERV 10–12 air filters built for homes with shedding pets, seasonal allergies, or mold and fine-dust problems. They capture pet dander, mold spores, fine pollen, and dust-mite debris that lower-rated filters let recirculate — without choking your system's airflow.

Every filter is made in the USA and ships flat-rate nationwide — same shipping on 1, 2 or 3 packs. Not sure of your size? Use Find My Filter to match the size printed on the cardboard edge of your old filter. No pets or allergies? Everyday Defense (MERV 6–8) may be all you need. Fighting smoke or bacteria? Step up to Maximum Protection (MERV 13–16).
