N95 reprocessing by low temperature sterilization with 59% vaporized hydrogen peroxide during the 2020 COVID-19 pandemic

Maimuna Jatta et al.

Summary: The study demonstrated that decontamination of N95 respirators with 59% hydrogen peroxide vapor has no significant impact on filtration efficiency or fit testing. This method can be safely used to decontaminate single-use N95 respirators in healthcare settings facing shortages during the COVID-19 pandemic. Further research and implementation may help address the ongoing challenges related to PPE shortages worldwide.

Use, re-use or discard? Quantitatively defined variance in the functional integrity of N95 respirators following vaporized hydrogen peroxide decontamination during the COVID-19 pandemic

C. Levine et al.

Summary: This study investigated the effects of vaporized hydrogen peroxide (VHP) decontamination on the fit of N95 respirators, revealing a downward trend in functional integrity of certain models after multiple cycles. It also found that the fit of 3M 1870 N95 respirators was significantly reduced after decontamination and testing on a second user. Inconsistencies between qualitative fit test and QNFT results were uncovered, highlighting potential limitations of current fit testing methods.

Effect of various decontamination procedures on disposable N95 mask integrity and SARS-CoV-2 infectivity

Jeffrey S. Smith et al.

Summary: The study tested the feasibility of VHP, UV, and ethanol decontamination on N95 masks, with ethanol and UV showing different degrees of degradation, while VHP treatment showed no significant change. Ethanol treatment was effective in eliminating detectable SARS-CoV-2 RNA in a virucidal experiment.
