A UCLA study looked at different ways of decontaminating an N95 respirator. They found that using vaporized hydrogen peroxide was more effective than using dry heat, ultraviolet light or ethanol spray in decontaminating the respiratory. However, the respirator can only be decontaminated thrice before it loses its effectiveness in filtering out the COVID-19 virus. (Lauren Man/Assistant Photo editor)

Some respirators can be effectively decontaminated of the coronavirus and reused, which could help doctors when protective equipment supplies run low, UCLA researchers found. When using vaporized hydrogen peroxide for 10 minutes, the researchers found no traces of SARS-CoV-2 on N95 respirators, said Amandine Gamble, a postdoctoral researcher at UCLA and a co-author of a study published in September in the Emerging Infectious Diseases Journal.
