Does anyone know if this system adds back minerals? I am asking this because pure water is very bad for your health because water tends to "attract" minerals (from your body).
vektekI'm a bit confused. I can't seem to find anything on a "gack" filter. Also, how can the filter leave water soluble minerals but somehow filter water soluble nitrates, pharmaceuticals and salts as it claims? Do you have any more information on this?
