Product review (1 stars): Black water.
Installed the two brand new filters and this is what came out right away on both filter instals.  I proceeded to re install the old PUR filter and no black water came out.  I don't know what it is but i am not risking drinking water from these filters.  Will pay for the PUR filters even if its more expensive.  *side note: box says "manufacture in Brooklyn NY but on bottom of box it says MADE IN CHINA.
