Shop AC Filters by Type
Every air conditioning system is different. Choose the right filter material to balance airflow, filtration, and budget for your specific cooling needs.
- For Maximum Airflow: Fiberglass filters are a budget-friendly choice that protects your AC unit from large debris without restricting airflow.
- For Most Homes: Pleated MERV 8 filters provide the ideal blend of superior filtration for cleaner air and strong airflow for efficient cooling.
- For Allergy Sufferers: High-efficiency MERV 11 or MERV 13 filters trap fine particles like pet dander, mold spores, and pollen, providing relief during allergy season.
Shop AC Filters by MERV Rating
Selecting the right MERV rating is crucial for your air conditioner. A higher rating cleans the air better but can make your system work harder. Find the right balance for your home.
- MERV 8: The best all-around choice for most homes, providing excellent filtration with minimal impact on airflow.
- MERV 11: A great upgrade for homes with pets or moderate allergies.
- MERV 13: Recommended for superior allergen capture, but confirm your AC system can handle the increased airflow resistance.
