  • MERV = “Minimum Efficiency Reporting Value” — this is used to rate the overall effectiveness of an air filter. Below you will find a link to 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.
