ASU researcher tests face mask efficiency before and after sterilization
Wearing of protective face masks is seen as providing a significant defense against exposure to the type of coronavirus responsible for the COBID-19 pandemic. But does sterilization of the masks make them more or less effective in shielding users from airborne particles and vaporous droplets that can spread the infection? Fulton Schools Professor Paul Westerhoff and fellow researcher Pierre Herckes, a professor in ASU’s School of Molecular Sciences, are leading work funded by the National Science Foundation to answer the question. For now, they say, wearing a mask, whether it’s been disinfected recently or not, is the wise choice — along with washing your hands.
