With the enhanced virulence of the Omicron variant, some experts are urging us all to upgrade cloth and surgical masks to the much more protective N95s, but supply remains a concern. The limited supply is why this advice has so far been held back, bu
research indicated that an N95 could be decontaminated and reused a couple of times without being compromised, a new study from a team at Beth Israel Deaconess Medical Center in Boston has now shown that even after 25 rounds of VHP decontamination, the N95 respirator was just as good at fitting on the face and filtrating particles.are a type of mask fitted very closely to the face to create a seal.
From June to August 2020, the researchers assessed seven volunteers who were using 3M 1860/1860S N95 respirators. Each volunteer was fitted for an appropriately sized mask , and then the team used VHP to decontaminate the respirators after use. Every few cycles a quantitative fit test was conducted – this is where specialized equipment checks how much air is leaking through the seal. Every five cycles a filtration efficiency testing and a qualitative fit test – a test where the mask fails if the volunteer can taste or smell anything while wearing the mask – was undertaken. After 25 decontamination cycles, the team found no changes from before the first cycle to the end.
In the meantime, this VHP research shows that medical staff don't need to be replacing masks every few uses to keep them up to code after decontamination.
