Replacing Your Air Filter

What Is MERV?

MERV stands for Minimum Efficiency Reporting Value. Basically, MERV rating tells you, “how effective is my air filter?”

The common particles that filters are tested for include pollen, dust mites, textile and carpet fibers, mold spores, dust, pet dander, bacteria and tobacco smoke. Most residential systems can adequately remove airborne contaminants with a filter rated MERV 7-12. MERV 13-16 is typically found in hospital and general surgery settings and can also be used in homes.
