What is a MERV Rating?

MERV, or “Minimum Efficiency Reporting Value,” is a rating system ranging from 1-20 that measures how efficient an Air filter is when capturing particles. The higher the number, the better the filter is at capturing particles. A typical MERV rating for home HVAC systems is between 8-13, while facilities like healthcare offices and hospitals use filters with a MERV rating of 14-20.
