Owing to the coronavirus disease 2019 pandemic, there is a global shortage of masks needed to protect health care personnel.1,2 The US Centers for Disease Control and Prevention has suggested the potential reuse of disposable respirators to conserve available supplies.3 A study by Viscusi et al4 evaluated various sterilization methods for reuse of N95 masks. Although surgical masks should not be used as a substitute for N95s owing to lower fit quality,5 a randomized clinical trail by Radonovich et al6 found that there was no significant difference in the incidence of laboratory-confirmed influenza among health care personnel who used N95s vs surgical face masks. The Centers for Disease Control and Prevention listed KN95 masks (the Chinese version of the N95) as suitable alternatives to N95s when N95s are not available. However, to our knowledge, there are no studies regarding the effects of sterilization on the filtration efficiencies of KN95s or surgical face masks. The goal of this quality improvement study was to test the feasibility of reusing KN95s and surgical masks.
