Product review (1 stars): Left black particles in water - bad taste
I decided to try a replacement MWF filter to save some money - I will not do so again. Maybe I received a bad pack or something, but the filter from this pack left small, black specs floating in the water and had a charcoal like taste to it. We ran it for a few days to see if it would improve, but it did not. When I went to try a 2nd filter from the same pack there were large black particles on the underside of the seal when I pealed it back. Amazon refunded it without question, but hopefully the manufacturer can improve on the quality control to prevent this from happening to someone else.
