Baubles and Bangles

In the future, our own personal air purifier may defend us from all that nasty air outside.

Worn on the wrist, the Hand Tree design sucks up and filters polluted air, and recycles it back into the atmosphere. It was created by Alexandr Kostin, a semifinalist in the Electrolux Design Lab Competition.

The purifier gas a refillable carbon filter, a rechargeable battery and an organic light-emitting diode screen.
