Product review (5 stars): Who would ever really know?
It looks pretty and replaces easily. How would any consumer know if it filters what it says it does with out specialized measuring devices? It is pricey but promises to do the best job. The water looks clear and tastes fine.  The Amazon page description as well as the product web site both lead me to order the wrong filter at first. Return was easy and the right one was sent. I really try to read full descriptions and figure out exactly what I am ordering but I usually miss some small detail and end up with the wrong part.  This time both sites lead me wrong.
