What Is MERV?

MERV means Minimum Efficiency Reporting Value, it is a number assigned to a filter based on its minimum tested efficiency data at a known test condition. The higher the MERV rating the higher the efficiency the filter media is at catching smaller particles in the air. Please see the attachments below for literature on understanding MERV ratings and how they are determined.


Replace every 6 months if you have heating & cooling OR every 12 months if you only have heating. If you have a dusty environment or shedding pets you may need to replace your filter more often.
