Product review (1 stars): TOTAL JUNK, DO NOT BUY!
I bought these filters to replace my GE OEM filter.  WHAT GARBAGE!  The fit was perfect but that's where it ends.  It turned the water black.  I kept running the water through the filter.  It began turning from black to gray.  After flushing about 2 or 3 gallons of water through the filter it was clear, but not without black strands of charcoal floating in the water.  After running over 5 gallons through the filter and still getting the black strands floating in the water, I took it out and put the plug in.  It's been over two weeks since I pulled the filter and I still keep finding black strands of charcoal floating in my water.  This JUNK OF A FILTER contaminated my water line in my refrigerator between the filter and the dispenser so it is not like a filter would stop the problem.  I don't know how long it will take to purge the line but I'm pissed off that I keep finding these black strands in my water.  They should stop making this filter because it is total GARBAGE.  I'm surprised they haven't been sued.  Thanks for screwing up my refrigerator water sentinel!  Anyone wanting to start a class action law suit, I'm in.
