Product review (3 stars): maybe it's a fluke
I put the filter in my frig as usual and black stuff came pouring out the first 4 times I used the water dispenser.  Kinda yucky looking.  this was the first time something like this happened and I have had frig's with water filters for years.  Hoping it is just the 1 filter and not all 3 of them.  Maybe it is supposed to be that way.  Water is clear now coming out.
