Most water purifiers don’t remove viruses:

Pune: Despite loud promises that these gadgets suck out disease-causing bugs from drinking water, most water purifiers sold across India do not completely eliminate waterborne 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 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. However, NIV refused to divulge any brand names. But many advance water purifiers remove the viruses from the drinking water.
