Product review (2 stars): Lost out with the 2 pack
Purchased a 2 pack to avoid having to reorder. The 1st filter worked fine. 6 months later installed the 2nd filter of the 2 pack and water tastes like plastic and chlorine. I've washed gallons ($ and wasteful) of water through it. Contacted the vendor who suggested I remove it and immerse it in more water... still tastes bad.  Defeats the point of a filter-- so now I'm stuck with the 2nd of the 2 pack.
