Multilayer masks most effective at preventing aerosol generation: Study

According to IISc, when a person coughs, large droplets (>200 microns) hit the inner surface of a mask at a high speed, penetrate the mask fabric and break up or "atomise" into smaller droplets, which have a greater chance of aerosolisation and thereby carrying viruses like SARS-CoV-2 with them.
