Nov 18, 2020·Adding a polypropylene filter to a two-layer cloth mask can increase filtration efficiency from 35% to nearly 70%. Caution about vented masks: Masks with exhalation valves or vents should not be worn to help prevent the person wearing the mask from spreading COVID-19 to others. That is because the vent allows unfiltered air to escape.

"Filtration Efficiency of Surgical Masks" by Erin Sanchez

Feb 24, 2011·For 1.0 um particles, the efficiency was 58% to 75% for unsealed and 71% to 84% for sealed masks. For 2.0 um, the efficiency was 58% to 79% for unsealed masks and 69% to 85% for the sealed masks. The data were statistically significant and indicated that surgical masks were associated with very low filtration efficiency.
