Researchers in Israel recently unveiled a new type of mask that could save lives, money, and the environment! The invention is a reusable face mask that can clean itself. The mask plugs into a USB charger, which then heats up the mask’s layer of carbon fibers to about 158 degrees. This temperature is hot enough to kill any lingering viruses that could be on the mask. The reusable self-cleaning mask could be a boon for healthcare workers and hospitals, as well as the environment. “You have to make it reusable and friendly, and this is our solution,” said the mask’s developer, Yair Ein-Eli.
