All,
 
As a side note, if you saw the original version of the Stanford item, they have since expanded on it significantly, including adding many disclaimers. https://stanfordmedicine.app.box.com/v/covid19-PPE-1-1

Subject: [DCHAS-L] N-95 disinfection and reuse
 
Colleagues,
 
On 25 March the Stanford School of Medicine published a nice Q&A on the shortage of face masks and N-95 respirators. See file:///Users/pareinhardt/Downloads/mask-ppe-EBM-Stanford%20Medicine%20v1.2-3-25-2020.pdf
 
On pages 5-6 there is a good discussion of the various methods that can be used to disinfect N-95s, including a helpful table and references. One refence shows that hot water vapor from boiling water for ten minutes is an effective decontamination method.
 
At Yale, we plan to use vaporized hydrogen peroxide to decontaminate and reuse N-95s using the methods described here:
