The NCCO reactor combined with active oxygen generator to trap and expedite the decomposition of formaldehyde and volatile organic compounds (VOCs) and other harmful gaseous pollutants and release harmless water vapour and carbon dioxide. Because the pollutants are completely decomposed, the NCCO
reactor is continuously regenerated and helps to extend the life cycle. Thus, it attains high efficiency of air purification



Nano Confined Catalytic Oxidation(NCCO)air treatment technology is developed by a partner of Hong Kong Science Park, RHT Industries Limited, in collaboration with the member of the Entrepreneurship Program of the Hong Kong University of Science and Technology.

The core structure of this unique air treatment technology is an active oxygen generator combined with NCCO Reactor. The active oxygen has been emitted from the generator and can effectively kill bacteria and viruses, as well as destroy the molecular structure of harmful chemicals.

The NCCO Reactor consists of a large amount of granular catalysts, which are man-made mineral that contain nanotubes made of transition metals.

NCCO air treatment technology focuses on the decomposition of pollutants instead of its adsorption, therefore no secondary pollution will be caused and the filter can be used for a long period of time.

The laboratory has proven that NCCO Reactor could be applied for up to 12 years for sterilization and decomposition of harmful substances.

The testing reports show that it can effectively remove up 99.9% of carcinogens, influenza viruses, Staphylococcus aureus, Escherichia coli,
human coronaviruses…etc.

A research paper of University of British Columbia 2012 stated that NCCO air treatment technology performs better than “automatic sterilization ion” and photocatalyst technology. NCCO air treatment technology can effectively remove
ammonia and formaldehyde
