A wearable air purifier, you can strap the Airdog Fitair to your arm, put on the mask, and go for a run.
You'll have a fresh stream of purified air blown directly in your face as you go.
This is a cool looking device, especially if you live in a city with lots of pollution.

Maybe I'm hoping for too much, but I'd have liked if the strap doubled as a fitness This device then could monitor your heart rate, or your [UNKNOWN].
Or if the purifier itself was smarter and could let you know about the quality of the air you'll be breathing in the atmosphere.
