What does MERV stand for?

MERV stands for Minimum Efficiency Reporting Value, which is a critical standard that rates the effectiveness of air filters. This metric provides a numerical value that indicates the filter's ability to capture particles of different sizes. Filters with a higher MERV rating are more efficient at trapping smaller particles, resulting in better air quality. Understanding MERV ratings is essential for selecting appropriate filters for various applications, such as residential or commercial HVAC systems, as they directly influence the system's performance and air cleanliness.

Recognizing the importance of MERV in evaluating filter performance is fundamental for anyone involved in the air filtration industry, as it helps in making informed choices regarding filter selection to achieve desired air quality standards.
