Stanford researchers confirm N95 masks can be sterilized and reused with virtually no loss of filtration efficiency by leaving in oven for 30 mins at 70C / 158F

It also says to not soak it in any alcohol or chlorine based liquids, since it removes the static charge in the microfibers.

First I have heard about a "static charge" being part of the 95 mask's methodology.

However that charge eventually has to dissipate over time and likely thru use.

I would think any water trapped, the exhaled breath is rather humid, would absorb a significant amount of anything statically charged, and heating would not replace the static charge that is lost thru burning off the moisture.

And how fast I have no idea, so this idea of gaining extended use maybe mute.
