For city-dwellers sometimes walking down the street means breathing in the dark cloud of smoke from pollution. It feels like having an exhaust pipe blowing directly into your face. You cough, suffocate, burn your eyes and look like you just came out of a coal mine. What if there's a face mask that could filter the air. Not just a simple cloth air filter but something far more advanced. It processes the air, removes the pollutants and purifies the air to make it seem like your breathing fresh air all the time.
