Hello. I just purchased 3 new GE SmartWater MWF cartridges for my refrigerator. The water running through the old filter was starting to run quite slowly, but was still running clear. I installed one of the new cartridges, and am now seeing what look like small, clear "potato flakes" in the water. There were a lot of them at first, far less now but they are still there. I have run about 3 gallons of water out (twice what instructions said) and am still seeing them. The water is running much, much faster than it was before I installed the new filter, but again I am concerned about what I am seeing in the water. Does anyone have any idea what it is that I am seeing? Is it harmful? Any replies will be greatly appreciated, thanks!
