Check carefully what is removed.
Water hardness (alkalinity) is typically not removed by any simple flow-through

Indeed, I think this is the real deal. The Zerowater filter contains (is mostly)
mixed-bed ion-exchange DI resin, not ion-exchange "softening" resin.
Zerowater provides a conductivity/TDS tester which can't discriminate between
hardness ions (Ca, Mg) and salinity ions (Na) - the only way to reduce
conductivity/
TDS of water is to remove dissolved ions (actually, replace them with H+ and OH-
ions that associate into water).
This raises a good point about Zerowater; you really don't want to drink it,
any more than you would distilled or DI water. I'll use it to reduce the
hardness
of (carbon-filtered) tap water for coffee, but not for drinking.
