Bottom line is there is no justification to replace tap water with bottlwd water unless your house or infrastructure has some form of underlying issue. And let's be honest, just because something is sold by a big corporation doesn't necessarily make it safe.(er)
I think this is true, I think we have been conditioned to think that bottled water is safer than tap water. Multiple tests/studies have shown plastic particles in bottles water and depending where it is stored and its temperature through transport and other things can increase the amount of particles in the water which our bodies do not process well. If you think you need a better filtration system then add it at home. I can look no further than my dad in in his mid 80's very healthy has preached for 25+ years saying bottled water industry and its message of being better than tap water was one of the biggest racket going.
