Czech company Retap has developed a unique technology that allows households, offices, or production areas to remove dangerous viruses, bacteria or toxic gases that evaporate from furniture, electronics, carpets, or artificial flooring.

How does the invention work? The contaminated air flows continuously in nano purifier through a set of photocatalytic filters. On the filters are completely decomposed toxic gases, microorganisms such as bacteria and viruses, fungi and other organic-type impurities. Photocatalysis is the natural decomposition of some substances by light in the presence of a catalyst. The purifier then generates common compounds such as water vapor and carbon dioxide.
