MERV = 'Minimum Efficiency Reporting Value' this is used to rate the overall effectiveness of an Air Filter. Below you will find a table that measures the MERV strength and tells you the Application of each unit's effectiveness. In general an Air Filter with a higher MERV Rating is more effective and has a broader application, but most residential homes will find the best use from an air filter between the 5-12 MERV rating.
