New decontamination protocol permits reuse of N95 respirators

The COVID-19 pandemic has created a shortage of personal protective equipment, including “N95” respirators, needed by frontline healthcare providers. A new protocol using aerosolized hydrogen peroxide to decontaminate N95 respirators could allow them to be safely reused in some hospital settings, where the disinfectant is already being used for other decontamination purposes.
