Pure? Think again

TOI reports: Despite loud promises that these gadgets suck out disease-causing bugs from drinking water, most purifiers sold across India do not completely eliminate water-borne viruses like Hepatitis E, says Pune-based National Institute of Virology.

A study by the government-funded body that conducts research on communicable diseases and viruses evaluated eight domestic water purifier brands. It found only two - one equipped with a hollow fibre membrane and the other with a gravity-fed filter - could completely remove the viruses.

The study also found no standards existed for virological evaluation of water purification devices in India and called for well-defined parameters.

The NIV relied on the United States Environment Protection Agency's (USEPA) guide, standard and protocol benchmark for testing microbial purifiers.

The study was conducted by senior deputy director and head of the NIV's hepatitis division, Vidya Arankalle, and scientist Vikram Verma. The Indian Council of Medical Research (ICMR), ministry of health and family welfare, government of India, extended financial support to the study conducted by the NIV scientists.
