Breathe Easy: The Filter Scarf

Here's a filter you might want to wear whether or not you're breathing urban air. Designed by Carl Hagerling, Claes Nellestam and Martin Pråme, this minimal gray scarf is lined with a flexible carbon filter that cleans all you inhale. It's also equipped with an air quality sensor that let's you know when to scarf up. Although personal-protection-turned-fashion is sad comment on the air quality of cities, this could also be a great way to prevent the spread of colds during the winter.
