1. Your filter size
Tip: the size is printed on the cardboard edge of your current filter as width × height × thickness (e.g. 20 × 25 × 1).Read our quick guide →
2. How many filters per shipment?
One per return vent. Most homes need one to four.
💡 Every extra filter takes another 10% off your whole order (2 filters = 10% off, 3 = 20%, 4+ = 30%).
3. MERV grade
Higher catches more, but too high can restrict airflow. Which grade is right for me?
4. Delivery frequency
