1. Know Your Size

Check your existing filter or furnace manual. Common sizes: 16x25x1, 20x20x1, 20x25x1, 16x20x1.

2. Choose Your MERV Rating

Higher MERV = more filtration but more airflow restriction. MERV 8-11 is good for most homes. MERV 13 for allergies.

3. Set a Replacement Schedule

Replace every 90 days (standard) or 60 days (pets/allergies). Set a reminder.
