Product review (5 stars): This one is good!
I saw a lot of bad reviews for filters, even ones that "claim" to be Samsung but are apparently knockoffs.  Well, these EcoAqua filters seem to work fine (so far).  I suggest that whatever filters you buy, look at recent reviews (not old ones) because it seems that some sellers start out selling a good product and then switch to something lousy.  I also suggest that you hang on to your old filter (don't throw it away) so that you can switch back to the old filter (temporarily) if you have to remove a cr@ppy replacement filter and return it.
