We able to get five days of use out of ours if we let them rest and decontaminate for five days between usage. Even after still pass the fit-test and work well - we just throw them away out of an abundance of caution. Even the ones we get from 3M South Korea at about $20 each winds up costing just pennies per hour.

If you don't mind answering, what decontamination method are you using? That CDC link merely refers mask users to the mask manufacturers. How have you found reuse to effect fit and performance? From the CDC page you linked: "Decontamination of an N95 FFR inactivates viruses and bacteria on the device, but does not restore the N95 FFR to “new” performance. Decontamination studies have evaluated the effect of the decontamination process on the fit and filtration performance of N95 FFRs; however, these studies did not consider the likelihood that N95 FFRs worn by healthcare personnel are likely donned and doffed multiple times before undergoing decontamination. N95 FFR performance will decrease as the number of hours and number of donnings and doffings increase. Repeated decontamination and handling of FFRs can damage the fit and filtration performance of N95 FFRs. Fit performance during limited reuse, including decontaminated FFRs, should be monitored by the respiratory protection program manager or appropriate safety personnel. Information about how to assess N95 FFR fit during limited reuse can be found below...."

  Sorry for the delay - we age and rotate resperators. The virus is presumed inactive after four days, so we have a weeks worth rotating at any one time. We store them in paper bags to let them dry out. Given we rarely actually have to go out of our home offices, it works well. 20 resperatore lasts about three months per person. If you need more - you can get 3M N95 from South Korea - about $200 for twenty.
