Zero Water makes water filtration systems that they claim remove 99% of total dissolved solids from water.
On the Water is the New Gold blog, a water-filter scientist warns against its use:
More dangerous is the fact that the Zero Water Filter removes 100% of the chlorine form the water. [...] Bacteria will grow in water that has no chlorine in it. [...] Also remember, ion-exchange resin is also a great medium for growing bacteria.
Will water filtered this way act as a harbor for bacteria?
