Product review (5 stars): AQUACREST  Water Filter Replacement
Just installed the AQUACREST replacement filter in our Samsung frig.  It fit snugly, just as it should, with no leaks.  Flushed the system with 2 gallons of water and saw no charcoal or other particles to report.  Seems to be working as it should.  Cost was less than $10, versus the Samsung brand replacement at greater than $40.
