Product review (5 stars): Best Investment I've made in a while.
My water tastes so much better!  Our city water has received EPA ratings that caused warnings about organic cabons (TOC), total  Trihalomethanes (TTHMs) and Haloacetic Acids (HAA5) that were all above EPA standards.  My current water filter did not filter any of these, or many other things out (as I discovered after reading about these filters and comparing them to my current one).  I bought them more for the efficiency of what they removed, but I have to say...WOW.  I feel like my water all tastes better now.  I fill my pitcher in the fridge from the fridge water and even use it to when making my tea for the day.  Much better flavor.
