A 22x26x1 air filter traps dust, pollen, pet dander, and other airborne particles, improving indoor air quality and protecting your HVAC system from buildup and wear.
We recommend replacing it every 90 days. However, homes with pets, allergies, or heavy HVAC use may benefit from changing it every 30–60 days.
MERV 8: Standard protection for dust and lint
MERV 11: Better for homes with pets or mild allergies
MERV 13: Best for capturing fine particles, allergens, and bacteria
