Title: Aerosolized Hydrogen Peroxide Decontamination of N95 Respirators, with Fit-Testing and Virologic Confirmation of Suitability for Re-Use During the COVID-19 Pandemic Document date: 2020_4_22

Snippet: Since the study was conducted during the COVID-19 pandemic, social distancing conditions limited the use of multiple test subjects. Therefore two (2) respirator fit-test subjects were selected (one male, one female), to test successful fit for the selected respirators. All respirators were subjected to QLFT on the first, fifth, and tenth rounds of decontamination. In order to continually monitor QLFT test outcomes on the same facepieces over the .....
Document: Since the study was conducted during the COVID-19 pandemic, social distancing conditions limited the use of multiple test subjects. Therefore two (2) respirator fit-test subjects were selected (one male, one female), to test successful fit for the selected respirators. All respirators were subjected to QLFT on the first, fifth, and tenth rounds of decontamination. In order to continually monitor QLFT test outcomes on the same facepieces over the course of sequential cycles of decontamination, only two of these were consumed by QNFT per model during each round of fit-testing. To conserve overall respirator use, respirators subjected to QNFT (with metal grommet in place from probe insertion) were returned for subsequent virologic testing.
