Gambarelli's Oxygena air purifying floor tiles

Contrary to what you might suspect, Gambarelli's Oxygena isn't a face cream, it's actually a floor tile that supposedly purifies the air around it. The tiles contain titanium dioxide, which reacts to polluting gases and eliminates them, all through a completely natural process — at least that's what they're claiming. The tiles are primarily designed to be used outdoors, to remove nitric oxide and nitrogen dioxide produced by vehicles and the like, but the company says they can also be used indoors, where they'll keep your bathroom and kitchen smelling titaniumy-fresh.
