Table 1 MERV rating of particles filters and make, model, and uses

From: Recent trends of microbial decontamination for occupational, industrial and domestic applications

MERV rating Performance to capture particles of sizes   Example of filter make and model Application and uses
(3–10) µm (1–3) µm (0.3–1) µm < 0.3 µm
MERV-1 < 20% N/A N/A N/A MERV-1 filter (G1) Capture large particles such as fibers, dust mites, and pollen
