How does it work?  

 In short, a titanium dioxide coating creates a photocatalytic reaction when exposed to the fluorescent light produced by the bulb.  This reaction releases electrons, or negatively charged particles.  At the same time, a positively charged hole is formed in its place.  This combination of negative and positive creates a very strong oxidizer called the hydroxide radical.  Odors that come into contact with the positively charged holes are broken down by these oxidizers into odorless compounds.
