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

Built for Performance & Durability

Air Bear filters feature a sturdy frame and wire backing for a perfect fit and proper airflow. The pleated design increases surface area, ensuring better filtration and airflow efficiency. Our filters help reduce exposure to:

  • Dust and Dust Mites
  • Pollen and Mold Spores
  • Pet dander
  • Seasonal allergens
  • Virus carriers

Selecting the Right Air Filter Size

Air filters come with both nominal and actual sizes. The nominal size is rounded to the nearest whole inch, while the actual size reflects the precise dimensions. Is your previous filter lacking size markings? Simply measure its length, width, and depth to find the correct replacement.
