Photocatalysis?

Photocatalysis is the natural decomposition of certain substances by the action of light in the presence of a catalyst. The catalyst does not change and it is not consumed during the reaction. 

The final product of the reaction are common and stable compounds, mostly water vapor and carbon dioxide. All micro-organisms like algae and fungi behave similarly.

This means that using photocatalysis will purify surface completely using only the action of light. See the principle of photocatalysis here:


Photocatalysis is a process of chemical decomposition of substances in the presence of a photocatalyst and light radiation.

In the case of Nanoaircleaner purifiers, it is the effect of UVA radiation from special fluorescent or LED lights onto the surface of photocatalytic filter coated with TiO2.

Why should you choose Nanoaircleaner air purifier?

Nanoaircleaner purifiers are the first product of its kind with photocatalytic cleaning-filtering of the air as the only and main filtering system. They are unlike any other purifier currently sold on the Czech market.

The Principle of Photocatalysis:

Photocatalysis is a physical process of oxidation on the surface of titanium dioxide excited by UV light.

Example: An organic substance, e.g. smoke, which mixes with oxygen under normal conditions, decomposes on contact with the activated surface of TiO2 mostly to CO2 and H2O molecules. TiO2 allows the reaction of atmospheric oxygen with organic pollutants, which would have not occurred otherwise.

The oxidation potential of 3.2V at the surface of excited TiO2 is able to decompose 99% of organic bonds and oxidize many inorganic molecules.

Nanoaircleaner purifiers work as air purifiers with unique and, it should be pointed out, proven capabilities.

During the testing of the prototype of this hybrid air purifier in the only Testing Institute in Brussels, it was found that the air purifier could decompose not only the impurities contained in the air but also carcinogenic and life-threatening substances, including formaldehyde and toluene.

Similar results in the degradation and destruction of these substances have not yet been achieved by any other method of air purifying.

All tested substances are destroyed by decomposition to CO2 and water.

Air purifiers have been developed in cooperation with the Department of Nanotechnology at the Technical University of Liberec and are patented.
