Product review (5 stars): and so far as I can tell they are just as good as Samsung name brand
these filters are less than one quarter the price of the Samsung brand name filters, and so far as I can tell they are just as good as Samsung name brand.

that being said I don't send water samples to a lab to be analyzed everytime I change the filters in my refrigerator.

+1 for being shipped to my front door in under two days.
