Filtration efficiency of 5.6–560 nm particles in ambient air of six N95 facemask types. Here the filtration efficiency is defined as proportion of particles that cannot go through the filters. The total efficiency of each N95 facemask for particles between 5.6 and 560 nm is listed on the top right corner of each graph. \( \mathrm{Efficiency}=\left(1-\frac{particle\kern0.17em numbers\kern0.17em for\kern0.17em facemask\kern0.17em with\kern0.17em filter}{particle\kern0.17em numbers\kern0.17em for\kern0.17em facemask\kern0.17em with out\kern0.17em filter}\right)\times 100\% \)
