Product review (1 stars): Had to throw away
While still in the "flushing the filter" stage, the water coming out of the dispenser was black.  That eventually stopped and the water coming out was clear again.  However, the water continued to have black and white "floaters" (possibly filaments of some kind?) even several gallons later. I even ran the dispenser without the filter for a few minutes to see if it was something in my water.  The water was clear without the filter.  When I reinstalled the filter, the floaters once again appeared in the water-even after flushing several more gallons through the filter.

I removed the filter and threw it away.  I'm now running the dispenser without a filter.

No fault of the seller-just my bad luck to get a faulty item.
