Product review (5 stars): Just as good as the name brand and $10 cheaper.
We have always purchased the Samsung replacement filter in the past, because we had tried a generic brand in the past, and it didn't fit correctly, even though it was advertised to fit our model, but we decided to try again, because the Waterdrop had good reviews and was $10 cheaper than the name brand.  We are very happy with our Waterdrop purchase. Good service and quality.
