Luke Pannell, a UK university student, created this "Breathe Air" bike helmet with a built-in air filter. It helps you with your asthma. And it helps you look like a Storm Trooper.
It covers the cyclist's nose and mouth with a shield behind which the filtered air circulates.Link (Thanks, Tom!)
Used air is expelled via a plastic tube when the cyclist exhales.
The helmet, called Breathe Air, was created by 22-year-old Brunel University industrial design and technology student Luke Pannell.
