What is a MERV Rating?
MERV rating, what is it? Minimum Efficiency Rating Value (MERV) is a numerical industry standard rating system developed by the ASHRAE, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers. The MERV rating system allows you the customer to pick from various air filters ranging in numerical value 1 (lowest efficiency) to 20 (highest efficiency). The higher the MERV rating the better the filter will perform at removing dust and smaller particles in the air. The MERV rating system helps you choose the right filter for what you need.
