Clothes Hangers Clean Clothes: Not every item of clothing we own needs to be laundered with soap and water after each wearing. But they could stand to be freshened up. Design graduate Lisa Marie Bengtsson has just the thing: a clothes hanger that has an activated charcoal filter.
Activated charcoal is treated with oxygen to give it extra absorbing powers to banish smells within a few days. The charcoal is contained in a glass chamber at the top of a ring-shaped hanger and is designed to be replaced after several hangings.
It's just a concept now, but it's clear that airing out clothing could save water and energy. via Gizmag
