Honeycomb Photocatalytic filter
                    TiO2 air filter is made of photocatalytic powder, photocatalytic powder can create high oxidizing molecules when under lighting. Therefore, the TIO2 photocatalytic fiter applied for some sterlizing functions, such as air purifier, disinfection cabinet etc.</br>
The make a TiO2 photocatalytic filter needs to using an aluminum honeycomb, and the powder painted on the surface of the honeycomb, then cover the honeycomb with an aluminum frame.
