To be frank, no. Your regular tap water, even after undergoing purification contains acidic PH which can lead to something called as Oxidation Reduction Potential. This basically means that over a period of time your body becomes more and more acidic and this can lead to health problems like tiredness, headaches, constipation and even severe diseases like cancer and arthritis. In fact when purified water comes in contact with the air, it starts absorbing carbon dioxide which leads to the acidity in water. Be it bottled water, distilled water, or Reverse Osmosis water; all of them contain high PH acid levels. It is said that Reverse Osmosis water is the purest form of water. That is one hundred percent true but what experts fail to reveal is that reverse osmosis often strips the water of essential elements that the body needs to survive.
