Hand Tree Air-Purifying Bracelets

As our world becomes more polluted, design students entering the Electrolux Design Lab competition are sprinting toward a solution. Here's one idea called the Hand Tree, a wristband that works as a personal air purifier that cleans the air around you, and perhaps across our entire planet.

The Hand Tree design concept was created by Alexandr Kostin of the Russian Federation. It's an anti-pollution bracelet that works like a plant, taking in carbon dioxide and releasing oxygen. At the same time, it removes dust, harmful gases, smoke and contaminants
