MERV is a standard used to measure the general efficiency of the filter. The MERV scale ranges from 1 to 16, and actions a filter's power to eliminate particles from 10 to 0.3 micrometer in size. Filters with higher rankings don't just eliminate far more particles within the air, but they also get rid of scaled-down particles.
