AIR FILTER SPRAY WITH METAL NANOPARTICLES KILLS 99% OF GERMS

Mixtures of three types were used in the experiment: with zinc, copper and silver oxides. No principal difference between them was revealed, all of them provide destruction of 99 % of microbes, with which they come into contact. But all of them lose their activity rather quickly, and after 24 hours it is no longer possible to guarantee reliable operation of the coating. Scientists are still looking for the best use of metal oxides, which could form the basis of a commercial product.
