A Czech SME has developed and manufactures a unique nano air purifier for interiors based on patented technology using photocatalytic filters. Microorganisms such as viruses, bacteria, molds, other organic-type impurities and toxic gases are completely decomposed into CO2 and water vapor thanks to filters of this type. The company is searching preferably for retail distributors to conclude a distribution services agreement.



In 2011 the Czech company together with the renowned scientific institutions of the Czech Republic started the development of titanium oxide nano-structures and their application to non-porous surfaces. After further development and testing, the technology of applying the so-called nano-photo-catalytic layer has been patented.
The newly developed technology has been used with nano air purifiers, and since 2016 the company has been producing the nano-air cleaner.

Principle of photocatalysis:
Photocatalysis is a natural decomposition of some substances, e.g. formaldehyde, toluene etc. by the action of light in the presence of a catalyst. In this reaction, the catalyst is neither changed nor consumed. The final products of the reaction are common and stable compounds, most often water vapor and carbon dioxide. All microorganisms behave similarly. This means that with the aid of a photocatalyst, air is only completely cleaned by exposure to light.

How the nano-air cleaner works:
The contaminated air continuously flows through a set of photocatalytic filters. Photocatalysis causes a natural decomposition of microorganisms by UVA light in the presence of a catalyst. In this reaction, the catalyst is neither altered nor consumed. Unlike ordinary filters able to eliminate microorganisms only up to 0.2 microns in size, filters of this type completely decompose bacteria, viruses, fungi and other organic-type impurities which are in size of nano, that is, hundreds to thousand times smaller. The purifier then generates a very small amount of common compounds such as water vapor and carbon dioxide.
With the titanium oxide photo-catalyst, the air is completely cleaned which is caused by acting of UVA light on a photo-active surface.
The outer shell of the purifier is made from natural materials such as solid wood, art glass, mirror glass, canvas, and ceramic tiles. Due to the absence of plastic parts, the nano air cleaner is able to decompose harmful substances in a room with greater efficiency. Photoactive nanofilter has the ability to regenerate itself, thanks to the self-cleaning process. Efficiency was verified by measurements in laboratories in Brussels, Paris, the Technical university of Liberec and in Hradec Kralove.

The SME would like to offer the nano-air cleaners to international markets, that is why the distribution services agreement is considered as the most suitable type of cooperation.

Advantages & innovations

Cooperation plus value: 
-Able to decompose viruses, bacteria, fungi below 0.2 microns in size unlike common air purifiers -No need of maintenance or cleaning of the photoactive filter -Decomposition of viruses and bacteria is happening just using catalysts and UVA light -It does not use ionizers thus it can operate continuously

Partner sought

Cooperation area: 
Sought are preferably retail distributors of medical supplies, domestic appliances and electronics, specialized distributors of air purifiers.

Type and size

Cooperation task: 
SME 11-50,SME <10,251-500,SME 51-250
