Product review (1 stars): While one filter works wonderfully, the other was terrible
This product comes in a two-pack.  While one filter works wonderfully, the other was terrible.  I felt like I was poisoning my family, including my cats.  The water tasted like it had impurities in it and it tasted like metal.  Conversely, the other (I tried it with my fingers crossed only because I ordered the two-pack), works just fine.  Inconsistancy is not the game I like to play.  Only wish I knew how to return just one!
