High-efficiency HVAC filters can remove up to 85% of air pollutants from a home or building space. These filters typically boast a MERV rating between 14 and 16 (16 is the highest rating).
Often made from pleated filter paper or synthetic polyester fibers, high-efficiency filters can trap very small particles of dust, pollen, mold and other irritants. These filters, however, are not very practical for residential use — hospitals or other “clean-room” environments use these industrial air filters to remove bacteria from the air. Keep in mind that the best HVAC filter for your heating or air conditioning system might not be the one with the highest MERV rating. An overly restrictive air filter can slow the rate of airflow, causing your unit to malfunction.
The ideal air filter is one that has the smallest effect on airflow, but removes the greatest number of air contaminants. HVAC filters with a MERV rating between 9 and 12 are usually the best choice for homeowners who want the best dust control possible.
