Product review (1 stars): I ordered a new one about a week ago and like some posts I've seen
I've ordered this filter at least twice in the past and have had no complaints.  I ordered a new one about a week ago and like some posts I've seen, it discolored the water making it a grayish/black color.  I asked for a replacement and Amazon sent me one within two days, free of charge, but I just installed the replacement with the same results--graying/black water from my fridge dispenser.  I cannot recommend this product and will avoid it from now on.  I suggest you look to another product.
