• •N95 respirators were decontaminated with vaporous hydrogen peroxide 25 times.•No alterations to respiratory integrity or filtration efficiency seen by 25 cycles.•Vaporous hydrogen peroxide does not appear to impact fit or filtration efficiency using this defined process.•However, implementation requires significant interdisciplinary coordination. 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.
