The Same N95 Mask Can Be Decontaminated at Least 25 Times, New Study Indicates

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.

sajz16 Yes this was being done, along with hospitals buying some expensive machine that used peroxide to clean masks in 2020 because there weren't enough masks for medical use. Now, supposedly, there are plenty of N95s being produced and stocked that you shouldn't have to 'clean' a N95.

Did this study include doing nothing to the masks but setting them aside for 4-5 days? Also, it's easy to replace straps with DIY elastics, ear loops with toggles, and a stapler. Definitely replace masks if visibly dirty, or become difficult through which to breathe.

kprather88 But does it need to be? How long does a contaminated mask remain infectious (if at all)? What if you just hang it up for a week and come back and wear it again?

kprather88 Will placing a used n95 in a paper bag and not using it again for at least 5 days work?
