We get several press releases about new and improved launches of water purifiers. As we perpetually toy with the idea of getting one but never take the final step, I read them with interest each time and never fail to be impressed by the number and variety of claims they make. Water Purifiers play the major role to maintain our health in modern life. There is UV technology and RO technology, and one has to decide which kind of purifier to buy based on one’s drinking water supply. A comparative study by Consumer Voice magazine tested 10 brands of water purifiers and found that most of them removed pesticide up to 100 per cent from the water used in the tests.
