Product review (4 stars): Waterdrop Filter vs. Samsung Original
Although the Waterdrop filter is attractively priced compared to the original Samsung filter #da29-00020b-1 haf-cin/exp, it's hard to make a comparison.  The Waterdrop filter physically installed as expected and doesn't leak into the pantry drawer.  The Waterdrop directions said nothing about needing to flush the filter (the SS owner's manual recommends flushing).  I've had to flush every other fridge water I've ever installed to see clear water.  The Waterdrop dispensed clear water from the start so I don't know why flushing it isn't mentioned.  I am concerned that the Waterdrop filter is made in China, recalling the dog food quality issues a few years back when the Chinese included Melmac plastic in the ingredients.  Also, the Waterdrop product testing notes only refers to NSF Intl. NSF/ANSI standard 42.  The SS filter refers to standards 42 and 53.  But the SS reference may be for another filter style, hard to discern their wording.  If the Waterdrop filter continues to function well, dispense clear water, and taste good, I will buy that brand again since I don't like the Samsung rip-off pricing, confusing testing notes, and confusing item nomenclature.
