It features battery powered fans to help you breathe and a built-in air purifier.

LG has unveiled an air purifier built into a face mask. The mask will be officially launched at an event later this month in Berlin, but a sneak peek indicates that the mask really is high tech. It also features a battery-powered fan to help you breathe more easily when wearing it. The mask comes in a special case equipped with UV-LED lights that promises to kill germs  – as well as charge it.
