How Many Times Can an N95 Mask Be Sanitized and Reused?

N95 respirators can be safely decontaminated without undermining functional integrity only two or three times, a government study showed.


Both ultraviolet light and vaporized hydrogen peroxide met the bar for killing off SARS-CoV-2 virus that causes COVID-19 without impacting fit testing for two rounds of wear and decontamination compared with control respirators.
