Photocatalytic Air Cleaning System Promises To Help Allergy Sufferers
...hich reacts with a titanium dioxide-based chemical catalyst as air passes through. The result is oxidation, which attacks and destroys microbes by disintegrating their DNA. The reaction also kills dust mites and mold. Goswami said that the photocatalytic process is superior to conventional techniques......m use ten times less. The new chemical is also a catalyst which means that it is not destroyed in the stitching process.
