MERV Rating, or Minimum Efficiency Reporting Value, is an industry standard for measuring the efficiency of air filters. The lowest possible MERV rating is a 1, while the highest efficiency rating is 20. Lower MERV rated filters will trap larger particulate in the air while filters with higher ratings will trap smaller particulate. Generally speaking MERV 8 filters are recommended for most residential use as are MERV 11. Again, the higher the MERV rating the greater the filter’s ability to trap finer airborne particulate.

Description

Please note that filters with a MERV rating higher than MERV 11 may be too restrictive for your residential system and negatively impact your home heating & air conditioning systems. Please consult your HVAC professional before installing any filter with a MERV rating higher than 11.
