Interesting…I bought a ZeroWater pitcher today and tried out the little TDS (Total Dissolved Solids) meter that comes with it. Our tap water is 235 PPM. So I hoped my fridge filter would reduce that down significantly. Nope, only went down to 200 PPM. The ZeroWater water measured 000 PPM (+003 PPM). ZeroWater is the real deal.
Of course, they do say that when the water from the ZeroWater filter starts reading 006 PPM to change it out. We’ll see how long that takes.
