Pardon me there might something I miss. How is it helpful to make a mask with no tissu for medical personnel ? It protects only from spits but not from aerial transmission. Isn’t it ?
Again, no offense, I just don’t understand.

@cyrilwaechter From what I know even normal medial masks have limited protective function. This one is a shield, so it only protects from large droplets as you wrote. is the best know protection
