Retired N95 inventor returns to save lives

Retired inventor Peter Tsai, who created the filter material used in N95 masks, is back at work in a makeshift laboratory in his home. He has been working long days, mostly for free, to help researchers, manufacturers and health-care workers to tackle questions about scaling up production and making masks reusable. Among his recent home-lab findings is that being heated at 70 ℃ for 60 minutes will sterilize masks when there are shortages of personal protective equipment.
