MERV stands for Minimum Efficiency Reporting Value. The MERV rating system is intended to be used to determine the filter's ability to remove particulates from the air. An air filter's MERV rating is a scale from 1-16 that describes the minimum efficiency of the air filter. A low MERV rating means that the filter does not remove as many particulates from the air.What is a MERV rating, and why does it matter?
The MERV rating, or the minimum efficiency reporting value , is a measurement of how effective an air filter is at removing dust and debris. MERV ratings range from 1-16 with higher ratings corresponding to smaller filter pores and thus greater air filtration. For example, an air filter with a MERV value of 16 will remove exponentially more air contaminants than a filter with a MERV value of one.What is a MERV rating and what does it mean?
MERV stands for Minimum Efficiency Reporting Value, which is a rating system designed by the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE). The rating indicates the size of particles the air filter is designed to capture.
