The face mask has become the need of the hour in the fight against covid-19. Early in the pandemic, worldwide shortages of surgical masks and N95 respirators led many people to make or purchase cloth face masks. However, face masks will likely still be required in certain settings for a while, especially with possible vaccine-resistant variants emerging. The researchers made simple face masks with 17 commonly available fabrics. Machine washing the masks didn't decrease their performance; in fact, masks containing cotton or polyester worked slightly better after washing because of pore shrinkage.
