Even though the modern life of today is increasing to live inside of the room (about 80-90% of our daily life), the indoor air is becoming more polluted by the extended use of chemical construction materials and with infectious bacteria. The World Health Organization (WHO) has continuously warned the bird influenza can be one of the world viral epidemic pandemic and is not avoidable epidemic to human. If this pandemic occurs to human then several hundred million people may be infected and several million people may lose their lives. It requires help of multi-technology such as mechanical engineering, hydrodynamic, microbiology, chemistry to eliminate such indoor air pollution. Our company organized a consortium of multi-technology with Sungkyunkwan University (microbiology and chemistry), Hankuk Aviation University (hydrodynamic), Ansan college of Technology (mechanical engineering) and has developed the Virus Killer. The corporation philosophy of INB Co., Ltd. is "realization of love for humanity through technology". I hope our development of the Virus Killer can be useful for human to be protected from bacteria and air pollution.
