MERV-rated Filter

Minimum Efficiency Reporting Value (MERV) is a rating from 1 to 16 that indicates the effectiveness of air filters. The higher the MERV rating, the denser the filter and the more efficient it is at removing small particles in the air. However, a higher MERV rating creates more resistance to airflow, thus requiring additional energy to push air through the filter.  For the cleanest air, a user should select the highest MERV filter that their unit is capable of handling based on the limit of the unit’s fan power.
