Product review (1 stars): Not something I want to let my family drink.
TDS (total Dissolved Solids) was 130 after replacing and before flushing.  Ran 10 gallons of water through new filter and the TDS is 110 at the lowest reading.  My tap water is 140 TDS and my local bottled water machine is 25 TDS.  I am not happy with this product and will return.  When my tap water is close in range to the TDS reading of this filter it makes me wonder.  Not something I want to let my family drink.
