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.What are MERV ratings, and why are they important?
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 the difference between HEPA and True HEPA?
These "HEPA-type" filters work in the same way as true HEPA filters, but they do not adhere to the same standards. The major difference in the true HEPA and the HEPA-type filters are their efficiency for small particles. They are often limited to 85 percent to 90 percent of airborne particles,...
