Rating MERV

The MERV rating of an Air Filter measures the effectiveness of a filter in removing particles of different sizes. The tests are done in a laboratory. Based on their size, the particles were divided into three categories. The smallest particles are particles ranging from 0.3 to 1.0um. Particles that are larger than that are considered large. Filters with a MERV rating of 17 or higher are considered very effective at capturing dust mites and pollen.
