All central air systems have standard air filters to keep particles from damaging your system. These filters are usually ½ to 1 inch thick. They protect your AC, but they don’t improve your air quality. We chose to make our custom media filters 5 inches thick to capture dust, pollen, and virus-sized particles that are flowing through your air.
How effective is your air filter?
Air filters are all rated from 1 to 16 on the MERV scale, based on how well they filter the smallest particles like pollen, dust mites, textile and carpet fibers, mold spores, dust, pet dander, bacteria and tobacco smoke.
According to the EPA, basic air filters rated between MERV 1 and MERV 4 are designed to protect your heating and cooling equipment from large, damaging particles. They are not designed to improve indoor air quality. They have limited ability to capture smaller particles like bacteria, viruses, pet dander, and dust mites.
Upgrading your standard filter to a higher performance filter increases your protection from pollutants and allergens. Filters rated between MERV 7 and MERV 12 remove more irritating particles from your air. Hospital and sterile rooms often use very high MERV ratings between 13 and 16. They filter the air at such a high level, it may hinder airflow in your system. Talk to one of our indoor air quality experts about what kind of air filter might be best for your home.
