A Greener Approach to Green Environments

 

Science & Research

PureLife™ is such a green technology that it works similar to photosynthesis. Using UV-blue light and the water in air, it oxidizes organic compounds and converts them into microscopic amounts of water, carbon dioxide and harmless byproducts. Instead of chlorophyll, the catalyst in PureLife™ is a proprietary form of titanium dioxide (TiO2).

Though the uses of TiO2 for environmental cleanup have been studied for decades, its potential has never been fully realized. Now researchers have discovered how to suspend these amazing semiconductor particles in a thin-film formulation that is patented for many uses. This proprietary formulation disperses the TiO2 evenly on surfaces and does not require heat for curing or activation. As a result, PureLife™ converts airborne and surface-bound contaminants at a rate that is 18 to 30 times that of other formulations. Surprisingly, the vital TiO2 in PureLife™ isn't consumed in the reaction. It keeps working for years, requiring no maintenance.

PureLife™ also is totally non-toxic and pH-neutral—meaning it's harmless to people, plants and animals. In fact, TiO2 is so safe it's used in sunscreens and chewing gum. After all, if TiO2 is swallowed, it's harmless—since it's inactive in the absence of light. This stands in stark contrast to catalysts like nanosilver, which don't need light to work and can destroy human cells and friendly microorganisms if consumed.

Purecology is proven science

The purifying powers of TiO2 nanocoatings such as PureLife™ have been studied exhaustively. They've been the subject of research at the University of California, Stanford University, MIT, the University of Wisconsin and Lawrence Livermore National Labs. The Environmental Protection Agency (EPA) and NASA also are investigating their large-scale application. And for several years now, the American Lung Association and Occupational Health and Safety Administration (OSHA) have been exploring their use for various environmental cleanup efforts.

Reduction of indoor air pollutants with titanium dioxide nanocoatings

As seen in this graph from an EPA study: "Final Report: Photocatalytic AIR Cleaner for Indoor Air Pollution Control," TiO2 nanocoatings dramatically reduce such common indoor air pollutants as carbon monoxide, formaldehyde, ethylene, and toluene.*

Bacteria decomposition using titanium dioxide nanocoatings

The Kyoto Microorganism Research Center and Osaka Hygienic Food Association have proven the efficacy of TiO2 nanocoatings in dramatically reducing such bacteria as escherichia coli, pseudomonas aeruginosa and staphylococcus aureus (MRSA).*

* It's important to note that PureLife™ is 18 to 30 times more powerful than the TiO2 formulation used in both of these studies!
