[Greenbuilding] Magic Carpets Suck Out Air Pollutants

[Stephen Collette]

Brent,

Nice thoughts on the carpet. I'm familiar with the titanium dioxide  
in Farrow and Ball paints, and other exterior plaster finishes as an  
air quality improver. Ultraviolet light though, that is interesting  
from an indoor perspective as there would be less or none indoors. So  
would it still work?

Time for some more of you science guys to wade in.
