Product review (2 stars): Like many others
Like many others, we received this filter as a substitution for the filter we have used for years. While I have not noticed any issues with the taste of the water, I did use a device I have that tests water's TDS (total dissolved solids) and in three different tests done over about a week, the filtered water had a higher reading every single time. Our tap water was around 140 and the filtered water ranged from 165-220.  I am not a water quality expert, but it sure seems like the filter should *reduce* the solids in the water... not increase that count. We will not order this brand again and I have canceled my auto subscription.
