Cloth-masked topics expelled an average of 19 contaminants per 5 cubic feet; sixty three% had been less than 4 μm in diameter. The second research used the same experimental setup, however studied a wider range of mask designs, together with a four-ply cotton masks. For every mask design, over 97% contaminant filtration was observed .
