I Bought the Zero water and a Pur water pitcher at the same time. The first few weeks the water was very similar, but that quickly changed.
The ZeroWater, became acidic and undrinkable after 4 weeks, while the Pur was still good. I used PH test strips and the ZeroWater was off the chart acidic while the Pur was still within normal range of the original tap water used on the PH test strips. I Do not recommend ZeroWater for this reason. My Pur is still going while the Zero is done.
The Pur Water system filters cost much less and work much better. I hope Zero hears these real life reports.
Reviewer is in unhappy mood. This person is quite happy with taste and stated that there is a room for improvement of taste. Please immediately contact the author of this review to discuss bad quality of zerowater filtration system and associated monetary loss in the amount of $20. Zerowater needs to offer any options to resolve the issue according to poster's claims.
