An RO water purifier uses membranes to purify water. The membrane in an RO water purifier is what makes an RO water purifier different from other types of water purifiers, because the membrane in an RO water purifier can remove dissolved chemicals from water. This is why an RO water purifier is considered the best type of home water purifier.
Bacteria and Viruses in water and the diseases that they cause are what worry most people and the reason why most buy a water purifier. More dangerous than the bacteria and viruses in water is the dissolved poison chemicals in water like Arsenic. These are silent killers with no symptoms for years and when health problems start showing, it is usually too late to treat it. Of all types of home water purifiers available, only an RO water purifier can get rid of Arsenic and other poiso chemicals in water. That is why we say that with an RO water purifier fitted in your kitchen, you can rest assured that you are getting safe drinking water at home.
