Product review (4 stars): but the taste of the water seems fine. i like the fact that it's much cheaper ...
hard to tell if the filter is working or not.. i have no way to test the water.. but the taste of the water seems fine.  i like the fact that it's much cheaper than samsung units.  i have been using samsung units, and i noticed built up of minerals at the bottom of my water dispenser, so i would imagine this unit cannot be worse than the samsung OEM filter.
