Product review (1 stars): I don't really know if this works
Water runs though it so fast that it sprayed the water filling area with water.  It didn't seem to slow the water down.  It also purged air bubbles for more than a month after installation which I had never experienced before.  Water still ran through it fast even when the indicator said it was time for a new one (when my past filters were already noticeably slower at filling cups).  I don't know if this actually filters the water.  Perhaps it has less filter media inside than genuine Samsung?  I will look elsewhere for my next one.
