Product review (1 stars): Paper fiber in water?
I ordered a "3 pack" of the Waterdrop filters.  The first filter seemed ok, or maybe I just did not notice what I saw with the 2nd and 3rd filters.  Shortly after putting in the second filter, My family started to notice what looked like paper fiber in the water.  It was very noticeable.  I decided to use the last filter of the pack and within a short time, there was something in the water that looked like broken up pieces of paper.  I don't know if it was a bad batch or what, but I definitely will not try again.  Drinking water is too important to take chances.
