Product review (4 stars): You will get what you pay for
I previously used an alternative water filter for my refrigerator, but I changed it to Samsung genuine water filter because of my baby.
It is about 25~30% more than competitive water filter, but Samsung filter makes better taste of water; simply I can say "it is sweeter". And I also ordered this filter because one of reviews fir alternative filter says that the alternative filter does not filter all harmful chemicals (I forgot what it was.)

So if you consider for your health, especially your children, I suggest to use it.

Only the reason I give 4 stars for this filter is that my refrigerator could filter slower than with the alternative filter. This Samsung filter might be doing more jobs than alternative filter? Hmm...
Other than that, I have no issue for this filter.
