If you guys were unaware, there’s a company called Battelle which has an approved sanitizing process. You need to setup an account with them and then you just ship them off when soiled..
I‘ve not sent any off yet as our burn rate has been extremely low, but I’ve had my account setup for months..
only thing - they won’t do p100 filters or KN95, only stamped N95 masks..
It depends on the N95 and the process. We only do 2 UVGI treatments before we waste the mask due to degradation concerns. I had a pile of studies on it a few months back, but here's one from my browser history:
Oh its the H2O2 system, thought it was UV.They claim a mask can be cleaned up to 20 times using vaporized hydrogen peroxide
Battelle cleared to sterilize N95 masks at max capacity, operate in other states to fight coronavirus PPE shortage<p>Columbus, Ohio (March 29, 2020)—The U.S. Food and Drug Administration has approved Columbus-based non-profit Battelle’s request to begin sterilizing surgical masks for reuse during the COVID-19 coronavirus pandemic.</p> <p>The FDA has amended its initial approval, granted early Sunday, now...www.battelle.org
Per the Procedure published by our departments OSHO Battalion Chief, it says "Do not use/sanitize a N95 mask or filter more than five times. After the fifth cycle, properly dispose of the N95 mask and obtain a new N95 mask or filter set."
Where I work, we are starting to look at rationing our N95 masks again. We used to have 3 different masks (one style w/ 2 sizes and 1 "universal" size) and now we have gone to a different mask style so lots of fit-testing is needed...N95 supply is intermittent on individual types leading to the need to frequently re-fit-test some users
PAPRs are still heavily backordered with many months of lead time
Colorado has a law (PHEW) that states workers have a right to use their own PPE if it:Where I work, we are starting to look at rationing our N95 masks again.

But I now have my own TR-600 PAPR system. I didn't have to wait too long to get it. All I have to do now is get it approved for use at work.
