[citation necessary] This refers to their Minimum Efficiency Reporting Benefit (MERV) score.[citation necessary] These ratings are utilized to amount the power of an air cleaner filter to eliminate dust with the air because it passes through the filter. MERV is an ordinary accustomed to measure the general efficiency of a filter. The MERV scale ranges from one to 16, and actions a filter's capability to remove particles from ten to 0.3 micrometer in size. Filters with higher scores not simply clear away extra particles within the air, but In addition they take out scaled-down particles.
