How Long Do Air Bear Filters Last?

How Long Do Air Bear Filters Last?

A Homeowners Guide to Air Bear Filter Lifecycles.

One of the most common questions we receive is how long can I expect your filters to last? It’s a good question, so let’s break it down by MERV rating and filter thickness and quality.

When it comes to maintaining clean indoor air and an efficient HVAC system, choosing the right air filter—and knowing when to replace it—is essential. Air Bear filters, known for their high performance and durability, are one of the best choices you can make for your home air filtration needs. The electrostatically charged synthetic material of Air Bear Media Filters provides superior efficiency for optimal HVAC performance. Finger-supported vertical pleats remain evenly spaced while maximizing dirt-holding capacity and industry leading low pressure drop.  

Air Bear filters with a larger depth/THICKNESS will have a longer life cycle due to its larger surface area. MERV ratings do not directly determine the filter lifespan.

MERV stands for Minimum Efficiency Reporting Value, a scale that measures how effectively a filter captures airborne particles. The higher the MERV rating, the finer the filtration.

  • MERV 8: Captures dust, pollen, and mold spores.
  • MERV 11: Adds protection against pet dander and smoke.
  • MERV 13: Filters out bacteria, virus carriers, and fine particulates like smog and cooking smoke

Tips to Maximize Filter Life

  • Check monthly: Even if your filter is rated for 6 months, inspect it regularly, particularly if you live in an urban/high allergy region of the country.
  • Use a reminder app or set calendar alerts on your phone
  • Keep return vents clean to reduce dust buildup. Cleaning in general can help reduce dust, dander and pet hair.  
  • Seal duct leaks to prevent unfiltered air from bypassing the system.
  • Sign up for a Subscription: We can send your filters automatically to your home on a set schedule.

Factors to Consider

  • Are you more prone to allergies?  If you have asthma or severe allergies, you may benefit from more frequent filter changes to mitigate airborne allergens. According to the Asthma and Allergy Foundation of America the top 5 cities for seasonal allergies are: Wichita KS, New Orleans LA, Oklahoma City OK, Tulsa OK and Memphis TN.  
  •  What are your surroundings like?   If you live in a urban area, your home will be more susceptible to more air pollution which may decrease your filter lifecycle. The American Lung Association has a 2025 list of the most polluted cities in America by particle pollution. The top 5 include: Bakersfield CA, Visalia CA, Fresno CA, Eugene OR and Los Angeles CA.
  • Do you have pets, smoke or vape? About 2/3 of U.S. households include a pet.  Our furry companions unfortunately shed hair and dander which can easily get into your system. They also bring in dirt from the outside. Smoking and vaping is known to create volitle organic compounds that are released into your indoor air.
  • Do you cook often?   If you’re an at home Gordon Ramsay you can benefit from checking your filters often, especially if your filter ais near your kitchen. Cooking can greatly change your home’s IAQ with the release of Nitrogen Dioxide, Carbon Monoxide, Sulfates and particulate matter. An upgrade to a higher rated MERV filter could be a good idea as well. 

Investing in the right Air Bear MERV-rated filter and replacing it on schedule can:

  • Improve indoor air quality
  • Extend HVAC system life
  • Mitigate harmful airborne particles
  • Lower energy bills
  • Deliver peace of mind for your health
