Overview of Deodorant Catalysts
Deodorant catalyst has excellent adsorption capacity of rotten fish smell (trimethylamine) and toilet smell (NH3, H2S) at low temperature of 5°C and high removal efficiency of trimethylamine, ammonia, hydrogen sulfideby catalytic combustion at 100°C.
Deodorant catalyst can remove kimch smell (methylmercaptan) at all temperature range above 5°C.
Deodorant catalyst is antibacterial product that contains Cu
