Bel-Air consists of a transparent (Pyrex) and white (aluminum) box, through which you can see the plant, and a fan. Its advantages to other filtering systems: no filters to change or to clog up as the plant basically replaced these. The plant in addition to keeping its decorative properties becomes a more functional object in your home. Currently only available as a prototype, you can see Bel-Air at Le Laboratoire in Paris until January 2008, after which it will travel to MoMA in New York to form part of the exhibition 'Design and the Elastic Mind' starting in February.
