Photo-oxidation catalysis is the activity occurring when a light source interacts with the surface of semiconductor materials, the so-called photocatalysts. During this process, there must be at least two simultaneous reactions occurring, oxidation from photogenerated holes, and reduction from photogenerated electrons.

Main Oxidation Reaction decomposes Harmful Organic compounds into Water(H2O) and Carbon Dioxide(CO2) ultimately.


And also generated radical species completely attack and kill Viruses, Bacteria.


Removes Indoor Air Pollutants such as Formaldehyde,
and Sick House Syndrome


The POCAF System can be applied for Private residences, Offices, Hospitals, Shops, Malls, Sports complex, Governmental buildings etc. by adding POCAF System to any room in the building or the duct system(see duct style POCAF item)


By using Photo Oxidation Catalyst, we can remove Bacteria, Viruses, odorants, VOCs.


The International Agency for Research on Cancer (IARC) under WHO announces fine dust and formaldehyde as Group 1 carcinogens.

General dust collection and adsorption filters have limitations in removing organic gases.

– Currently, HEPA filters that are used alone pass most of the molecular-sized VOCs.

– In the case of carbon filters, there is a limit to adsorption of VOCs. In other words, life is short and must be replaced frequently.

– However, the photo oxidation filter is semi-permanent due to the catalytic reaction that fundamentally decomposes into water and carbon dioxide and removes harmful gases.


The photo oxidation reaction has VOCs removal, antibacterial and antiviral effects by hydroxyl radicals generated on the surface by photoreaction, and is more effective in removing VOCs than a general air purifier.

Photocatalysts do not produce harmful ozone. Anion generators, however, produce ozone.

The false knowledge that a photocatalyst filter is ineffective is when the amount of application of the photocatalyst is low, when a material with little photocatalytic activity is used, or when the photocatalyst filter is manufactured using an ineffective substrate.

The unique odor of the metal oxide, a photo oxidation catalyst raw material, is completely harmless to health.

We design & produce the Photooxidation filters according to the air conditioning data of the building and install the Photooxidation filters to the duct as shown in the pictures of our website.  The installation can be made by our engineers or by your engineers.


The same POCAF filter can be installed in the duct as shown in the picture.  Therefore, after receiving your data for Condensing unit(chiller), Air handling unit & duct system, we produce the suitable size POCAF filter to install in the duct.  The installation location in ducts can be decided by our engineers. The quantity of POCAF filters will be decided by the buyer where, which & how many rooms he would like to sterilize.   For your information, if we make same size of POCAF photooxidation catalyst filter(150mm TiO2 honeycomb, filter size 352mm W x 642mm L x 230mm Thick)  as our stand type POCAF-9000 model, the price is as follows. The price of duct type changes accroding to the duct size.


 Installation charge will be added for cutting, install, setting of filters & ducts ; The installation can be done by our engineers or by the buyer.  The buyer shall pay for the trip, hotel charges if they invite our engineers.  Otherwise, the buyer may hire local engineers to install them with our installation manual.
