In this study, it was found that vaporized hydrogen peroxide is an effective option for supplementing limited supplies of N95 respirators during the COVID-19 pandemic. Reprocessing the respirators did not result in significant differences in fit or filtration efficiency.
N95 respirators were reprocessed using vaporized hydrogen peroxide to supplement limited supplies during the COVID-19 pandemic. In this study, we found no statistically significant differences in qualitative and quantitative fit or filtration efficiency with reprocessing. Filtration efficiency remained above 95% even at 25 cycles of reprocessing without statistically significant change from cycle 20-25 compared to cycle 0 (P = .10, P = .05, respectively). Vaporous hydrogen peroxide is an effective option to augment N95 respirator supplies. (C) 2021 Association for Professionals in Infection Control and Epidemiology, Inc. Published by Elsevier Inc.
