A funny thing happens when you add titanium dioxide to paint and then hit it with fluorescent light: bacteria die. Well, okay. Not so funny for bacteria. But it could be an effective way to destroy superbugs in hospitals, public and commercial facilities, schools and residential kitchens, baths and floors would be significant . Think about it. Just add titanium dioxide -- the white compound that makes the "M" on M&M candies -- to paint, put it on the walls and then turn on the lights.

In lab tests, Lucia Caballero from Manchester Metropolitan University, found that the food poisoning bacterium Escherichia coli was killed under normal, fluorescent light. Here's why: When the titanium dioxide absorbs energy from the light, a chemical reaction occurs that results in two molecules, hydroxyl radicals and superoxide anions. Both work to decompose microorganisms by causing cell rupture and leakage of vital composition.

With rising concern about the spread of hospital superbugs, this new kind of paint could be one cost-effective way to healthcare maintain hygienic standards.

Here is ultraviolet light in use it kills all kinds of stuff, they use it in barns to keep them sanitary and inside the vein to purify blood.

I have a unit in my house that generates ozone, negative ions, and sanitizes air using UV light. I have it stationed right in front of the central a/c intake.
I found it at the Oxyfresh website.

With all the crap that can live and grow in air conditioners somthing like that would be great actualy in the vent treating the unit wether on or off. Air conditioners are breeding ground for disease, but could you feel comfortable in Florida without one, I don't think so!!
