We first reported on the conceptual design of the Bel-Air living air filter back in 2007, and now everyone may breathe a little easier because it came to fruition as the ANDREA Air Filter and went on the market this week! The stylish air purifier, invented by French designer Mathieu Lehanneur with Harvard professor David Edward elevates common houseplants to heroic status as they eliminate noxious chemicals that pollute indoor air. Visit Inhabitots to see precisely how the ANDREA Air Filter works!
