I recently purchased a zero water filter that came with a gauge to test the water. In testing all waters available, it proved that the Zero water was far superior to all water, included most of the bottled water on the market.
Unfortunately, the very expensive water filter has an extremely short life and quickly shows the quality to be very much worse than most water available.
Moreover, it quickly leaves a very bad taste in the water and the filter must be replaced too often. I cannot afford the frequent replacement of the expensive filters and will be changing back to the Brita filter that I still have.
Review about: Zerowater Water Filter.
Reason of review: Bad quality.
Monetary Loss: $70.
I didn't like: Less than one month span.
