Why do Homeowners Choose Air Bear Air Filters?

When choosing an air filter replacement, homeowners deserve a reliable product that effectively captures airborne particles and keeps their furnace and air conditioner running efficiently.

Our long-lasting pleated filters offer superior dust-holding capacity while maintaining excellent airflow. Made in the USA, our filters are available at competitive prices with fast shipping—most orders ship within 24 hours!

When should you replace your furnace filter?

Air Bear filters offer superior performance compared to standard fiberglass filters and typically last up to 90 days. However, you may need to replace yours more frequently if:

• You suffer from severe allergies
• You live in an area with heavy traffic or air pollution
• You notice visible dust buildup on the filter
• You have pets in your home 

A quick visual inspection can help—if your filter looks dirty or clogged, it's time for a replacement!

Choosing the Right MERV Rating

MERV (Minimum Efficiency Reporting Value) measures an air filter’s ability to capture airborne particles. Air Bear filters are available in three MERV ratings: 

• MERV 8 – Captures 90% of airborne particles (Comparable to MPR 600, FPR 4-5)
• MERV 11 – Captures 95% of airborne particles (Comparable to MPR 1000-1200, FPR 6-7)
• MERV 13 – Captures 95% of even smaller particles, including virus carriers (Comparable to MPR 1500-1900, FPR 8-10)

No matter what MERV rating you choose, you will improve indoor air quality over fiberglass filters. Learn more about MERV Ratings HERE
