Product review (1 stars): black water  nasty taste to it after it clears
first gallon was black.  Now it tastes like bleach.

UPDATE:  after trying a knock-off brand and getting similar (but better) results, I thought to give
sears another chance.  SAME PROBLEM.  I believe ALL the charcoal came out and my water tastes like bleach.
This has to be a health hazard.  my tap water is 1000x better.
