What is a Merv rating?

Minimum Efficiency Reporting Value, or MERV for short, is a filter rating system 
devised by the American Society of Heating, Refrigeration and Air conditioning 
Engineers (ASHRAE) to standardize and simplify filter efficiency ratings for 
the public. The higher the MERV rating, the higher  the efficiency of  the filter. 
Simply stated, a MERV 8 filter will remove 
smaller particles from the air than a MERV 3 filter. 
Be sure to check what MERV rating your furnace filters are what is best for your home.
