A newly advanced and refined air filter supported by special grants from Science and Engineering Research Board (SERB) that can disband the germs. 

Indian Institute of Science (IISc), Bangalore, has lead a research which is led by Suryasarathi Bose and Kaushik Chatterjee discovered that the ingredients commonly found in green tea like polyphenols and polycationic polymers can be easily used to suspend the germs and bacteria that accumulate in the the air filters. Over continuous usage, the existing air filters become a breeding ground for captured germs. The growth of these germs clog the pores of the filter reducing the life of the filter.

A study by the University of Chicago found out that Impure air might make our life shorter to the extent that Indians lose 5-10 years of their lives because of air-borne contaminants leading to respiratory diseases.The World Health Organization estimates that 4.2 million premature deaths globally are linked to ambient (that is, outdoor) air pollution, mainly from heart disease, stroke, chronic obstructive pulmonary disease, lung cancer and respiratory infections in children. 

After knowing the facts that how much impure air can be hazardous to us, the research of this air purifier was supported by SERB and a patent has been filed on this.
