MERV is a normal utilized to evaluate the overall efficiency of a filter. The MERV scale ranges from 1 to 16, and actions a filter's capability to take out particles from 10 to 0.3 micrometer in size. Filters with higher ratings not just clear away more particles in the air, but Additionally they take away scaled-down particles.
