Although a MERV rating (which stands for Minimum Efficiency Reporting Value) might sound complicated, it really just tells you how effective your air filter is in comparison to other air filters on the market. For residential settings, like your home or office, MERV ratings go from 1 to 13, with MERV 13 being the highest rated filter for a domestic environment. (ASHREA Tested MERV ratings actually go up to MERV 16, but 13-16 are usually for factories and medical environments with systems that are designed to handle the airflow restriction these filters will cause.)
