Everyday Defense

Everyday Defense is our baseline tier: pleated, electrostatically charged MERV 6–8 air filters that capture dust, lint, pollen, and dust mites without restricting your system's airflow. For homes without pets, allergies, or smoke concerns, this is the rating most HVAC pros recommend — replace it every 90 days and your system stays clean and efficient.

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. Need stronger filtration? Step up to Allergy & Pet (MERV 10–12) or Maximum Protection (MERV 13–16).
