Strap the Airdog Fitair to your arm and you won't have to worry about pollution as you run. The wearable air purifier is on show at, here in Las Vegas. A hose runs from the small engine and filter compartments on your arm to a mask on your face. As it works, you get a stream of fresh air blown directly at your nose.
You can also detach the filter from the arm strap. The power and purifier compartments click together to form a tower -- and then you have a personal air filter you can set on your desk.
I got to try on the Fitair at CES, and the stream of air felt great when I was wearing the mask. The mask is a pretty typical hospital mask though, so my own breath occasionally fogged up my glasses.
Without the mask, the stream of air from the stacked unit felt weak. I doubt it would have much of an impact, even in a small office or bedroom.
Still, Fitair will be a reasonably priced splurge. Airdog says it'll cost $100 (roughly AU$140, £80) when it comes out later this year.
