When should you replace your furnace filter?

Air Bear 14x201 air 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

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
