COVID-19 pandemic created a major turn around after it appeared, spreading the infection across the world. Masks are one of the things that we need to prevent further increase in the infection rate of the novel coronavirus. CTVNews reported that one of the most efficient face masks currently is the "N95". The man behind the popular face covering, Peter Tsai, may be needed by the world to make another breakthrough that could help fight the ongoing pandemic.
(Knoxville, TN)Peter Tsai, inventor who patented filtration material used in disposable N95 masks has stepped out of retirement to field calls from health-care workers in need of help in scaling up production.

This is possible because of the positive and negative charges that its filters contain. However, when Tsai heard that some of the physicians and other health-care workers are reusing the masks to prevent supply shortages during their operations, he immediately went back to work. He conducted experiments such as putting the face mask in an oven, leaving them out in the sun, washing them with soap, and steaming them. The most effecting method he found was keeping the face coverings in 160-degree dry heat for 30 minutes--it can be done by hanging them in an oven.
