Abstract

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.
