The stupidity of these neo-hippies on things like water. The purest you can get is distilled water from food grade stainless steel collected in glass jars. After that, reverse osmosis.
I love how the guy selling 'Live Water' thinks it's better because it's got minerals and natural bacteria in it, which is all fun and games till something nasty gets in it at the source.
If you want probiotics, either buy them in pill form or eat fermented foods. The minerals in water are generally unusable to the human body, but it's easy to add them if you feel the need.
Water is for hydration, distilled and r/o are the best for that. Don't overthink it with some eco-aware pseudoscience crap.
