Product review (3 stars): What the heck is this dark grey water?
Delivery, price and fit into the refrigerator were spectacular.  But 1/2 to 3/4 of a gallon of water had to be run through the filter to get to clean clear flow.  The DARK grey water that came from the first of three filters was a first for me.  I have replaced filters in 3 different refrigerators with different suppliers of these filters and never have I had visibly contaminated water come out of the dispenser like with this filter.  I doubled the water volume flush to about 1.5 gallons and water quality and taste seem ok.  I will try the second filter when the time comes, and if it produces the same volume of grey water, I will toss the third and never use the brand again.  If not, I will presume it was dislocated carbon in a faulty filter and move on.
