Interesting read... (interview with Peter Tsai):
"The man who made N95 masks so effective had been retired for over two years when the pandemic struck. But the inventor didn't think twice about returning to work when healthcare workers needed him most." https://edition.cnn.com/2020/07/15/health/n95-mask-inventor-coronavirus-sanjay-wellness-trnd/index.html

"Tsai patented the technology used to make the masks in 1995.
Here's how it works: To block up to 95% of the particles that come in contact with the mask, Tsai made the filters using the corona electrostatic charging method." https://edition.cnn.com/2020/07/15/health/n95-mask-inventor-coronavirus-sanjay-wellness-trnd/index.html

"Put simply, the mask's filter contains both positive and negative charges. It can attract neutral particles, like bacteria from viruses, and polarize those particles, trapping them before they can pass through the mask." https://edition.cnn.com/2020/07/15/health/n95-mask-inventor-coronavirus-sanjay-wellness-trnd/index.html
"Tsai tried a variety of methods: He left the masks out in the sun, put them in the oven, washed them with soap and steamed them, he said.
The best method, he found, was keeping the masks in 160-degree dry heat for 30 min, which can be feasibly done by hanging them in an oven."

Tsai's most preferred method for reusing N95 masks (simple!)
'buy 7 N95 masks and rotate them, using a new one each day. After using one mask, he hangs it in an isolated spot and doesn't use it again for 7 days,so any bacteria it catches become inactive' https://edition.cnn.com/2020/07/15/health/n95-mask-inventor-coronavirus-sanjay-wellness-trnd/index.html
