Product review (1 stars): More Like Brita Filters Than As Advertised OEM
These "advertised OEM" filters were shipped back with the clear, shrink-wrap unopened.  They are rated as OEM on the site, but the weight of the individual, empty filter is only equivalent to NSF/ASNI Standard 42, at best, which is much the same as filtering your water with "charcoal only" filters.  There was only one o-ring, my OEM has two.  There was a larger "square" opening for water input, mine has a much smaller "round" opening.  Samsung OEM filters are rated for BOTH the NSF/ANSI Standard 42 AND Standard 53, closer to Zero Water filters or even better.  My opinion,  if you really care about the quality of your drinking water, do what I'm going to continue doing, just buy the Manufacturer's OEM.  Yes, they are more expensive, but your refrigerator and you be much more healthy and happy in the long run!!!
