The model has shown that larger droplets of 50 microns or more blocked on the inner surface of the shield, but smaller or smaller smaller droplets have been capable of slipping through the gaps around the shield. The study also examined the effectiveness of cotton, polyester and nonwoven masks incough. The nonwoven mask was considered the most effective. However, the three facial masks have outperformed the face shield, blocking at least 80% of the viral spray.

And this is not the only study to conclude that face shields are not a form of useful protection. A study of September 1 published byFluid physicsCough simulated and sneezing From a mannequin mouth and a laser light used to visualize the expelled droplets.
