​Efficient disinfection solutions to combat PPE and disinfectant shortage during the COVID-19 pandemic (NSF RAPID)

  • COVID-19 pandemic has led to extreme shortage of masks
  • Filtration efficiency of masks deteriorates after times of reuse, loss of electrostatic charges is one of the major reasons
  • Our technology can disinfect and recharge masks simultaneously
  • Achieved controllable disinfection log reduction from 1 to 6
  • Can fully recharge masks, N95 masks keep filtration efficiency ~95% after 15 times of treatment
