The new mask has a USB port that connects to a power source such as a standard cellphone charger that heats an inner layer of carbon fibres to up to 70°C, high enough to kill viruses.
Ein-Eli said disposable masks, in high demand globally during the health crisis, were not economically or environmentally friendly.
“You have to make it reusable and friendly, and this is our solution,” he said about the invention.

Israeli researchers say they have invented a reusable face mask that can kill the coronavirus with heat by drawing power from a mobile phone charger.
The disinfecting process takes about 30 minutes - and users should not wear the mask while it is plugged in, said Professor Yair Ein-Eli, who led the research team at Technion University in Haifa.

The prototype looks like a standard N95 face mask, with a valve at the front and rubber bands to hold it in place around the head.
The researchers submitted a patent for the mask in the United States in late March and say they are discussing commercialising the product with the private sector.
It will likely sell at a $1 premium over the price of a typical disposable face mask, the researchers say.
