The MERV scale is designed to represent the worst-case performance of a filter when dealing with particles in the range of 0.3 to 10 micrometers. The MERV value is from 1 to 16. Higher MERV values correspond to a greater percentage of particles captured on each pass, with a MERV 16 filter capturing more than 95% of particles over the full range.
Air filtration standards differ between the U.S. and other countries. The American ASHRAE rating system does not account for changes in filtration efficiency due to electrostatic charge. These MERV ratings do not account for a decrease in efficiency over the first few weeks of use due to a drop in static charge.
