What is the purest form of water?
The purest water may very well be water that is distilled. However it is not good for you to drink it. I think the question you should be asking is what is the healthiest water to drink. Unfortunately in today’s world there is no place that has good drinking water available from a rain source. There have found contraceptives on the polar ice caps. This got there though the use of them and when eliminated from the body, found there way past the sewage treatment plants. Once evaporated along with the water, these chemicals are carried on the winds in clouds until they are returned to earth in the form of precipitation. So now we need to rely more on filters rather than RO systems and the like. Not all filters are created equally. There is a Japanese company that makes a filter that has no equal. I don’t remember the name off the top of my head but you should like it to it. The filter actually changes the structure of the water and it becomes more usable.
