Well the jury is in. It looks like the N95 surgical face mask is the best protection against COVID-19. According to chemist and physicist, Martin Fischer of Durham, N.C., campus droplets spread rather broadly and quickly without a mask. But bandanas and neck fleeces don't block saliva spray much at all which is giving people a false sense of safety
Duke University researchers developed a way of testing various types of masks to see which did the best job of stopping droplets coming from people's mouths, preventing spread of coronavirus. The most effective is the N95 BlacTec surgical face mask.
