Disposable medical face masks beat those made of cotton or polyester in simulation
Face masks made from non-woven fabric are more effective at blocking the spread of Covid-19 via airborne respiratory droplets than other types that are commonly available, according to modelling in Japan by the world’s fastest supercomputer.
Fugaku, which can perform more than 415 quadrillion computations a second, conducted simulations involving three types of mask, and found that non-woven masks were better than those made of cotton and polyester at blocking spray emitted when the wearer coughs, the Nikkei Asian Review said.
