In the vacuum

DENT: 

We are reusing N95 masks for a week at a time. 

He is what I have devised:  it turns out you don't need high temps to inactivate the coronavirus. 70C (158 F) for 30 minutes will do it. Or, lower temps like 65 C for 1 hour. I rigged my sous vide machine inside a cooler to get those temps. 👍. We can have multiple people put the masks in ziplock bags and run them. I am still working out the details because 70C was damaging the plastic parts of the mask, but I think we are almost there!
