Despite retirement, inventor of N95 masks works mostly for free fighting COVID-19

Your “Daily Dose of Uplift” for July 8th:
Peter Tsai invented the N95 mask in 1995, and retired two years ago. Needless to say, he was in high demand in early March when the COVID-19 outbreak was declared a pandemic and there was a massive shortage of the protective filtration masks desperately needed by healthcare professionals.
Tsai, originally from Taiwan now residing in Tennessee, was summoned from his retirement not only to help produce more of the necessary masks but also devise new sanitation practices effectively to make the masks reusable for the populous.
“I started working almost 20 hours a day,” he said, adding he’s doing it mostly on a volunteer basis. “But I didn’t mind.”
He tried everything from boiling to steaming the masks in effort to sanitize them while assuring their filtration was still adequate for medical use. He then published an emergency medical report (accessible in the link below) with his findings for the best possible ways to reuse his masks.
His biggest finding was that N95 masks can be heated at 158 degrees Fahrenheit for 60 minutes using a dry heat method without diminishing the filtration technology.
Let this be a window into the lives of medical professionals. They’re always on call in some way, shape, or form, even in retirement. Tip of the cap to Tsai for responding to the call in desperate times. He’s quite literally a life-saver.
