What is a MERV rating?
MERV stands for Minimum Efficiency Reporting Value. It is a filter performance rating developed by ASHRAE (the American Society of Heating, Refrigerating, and Air-Conditioning Engineers) to determine the efficiency of an air filter. The MERV rating indicates the filter's ability to capture particles, with higher MERV values signifying better filtration performance.
