Microwaving N95 masks

Researchers have devised a way to decontaminate N95 respirators using household supplies: glass containers, mesh from produce bags, a rubber band, and a microwave. Not only did their microwave-steaming method decontaminate respirators after one 3-minute treatment, but the respirators’ fit and function were maintained after 20 decontamination cycles. Metal within the masks did not spark during treatment. The researchers write, “This method provides a valuable means of effective decontamination and reuse of N95 respirators by frontline providers facing urgent need.”
