Self-cleaning mask can kill viruses with a phone charger

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. 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 fibers to up to 70 degrees Celsius, high enough to kill viruses.

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 commercializing the product with the private sector.
