Product review (1 stars): Poor quality, dishonest manufacturer
Trust the other reviews. This filter leaks.  Contacted the manuafacturer and they said they'll send out a replacement.  3 weeks later and still nothing.  No replies to emails.  If you want a true filter with NSF 53 and no leaks, then you should go for the samsung filter.  It is only a bit more expensive than this thing.  Otherwise if you want to save money, then go for the sentinel cheapie filter.
