This Water Purifier Provides Arsenic Free Water at Just 5 Paise a Litre: IIT-M’s Gift to the Nation

In 2013, a group of researchers at Indian Institute of Technology, Madras (IIT-M) developed an affordable nano technology-based water purifier. The aim behind the purifier was to provide safe drinking water without any microbial and chemical impurities, and to fight the problem of arsenic contamination that leads to many health hazards. It will now be used all across India.
