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: Based on a series of ten respirator decontamination cycles thus far, which to date have included two rounds of virologic testing, we found successful respirator decontamination by aHP and fitness for respirator reuse in this pilot study. We found that respirators were not substantively degraded (chemically or physically) by multiple cycles of aHP, as reflected in successful fit testing throughout the decontamination process. We used intentional v.....
Document: Based on a series of ten respirator decontamination cycles thus far, which to date have included two rounds of virologic testing, we found successful respirator decontamination by aHP and fitness for respirator reuse in this pilot study. We found that respirators were not substantively degraded (chemically or physically) by multiple cycles of aHP, as reflected in successful fit testing throughout the decontamination process. We used intentional viral inoculation onto specific respirator surfaces to thoroughly test for the ability of aHP to inactivate viruses, and to discern whether any differences in respirator construction (e.g. outer vs. inner surface fabric)
