Product review (4 stars): Nice OEM replacement
The filter is slightly different from the Samsung original filter it replaced. The top of the filter has only one o-ring whereas the Samsung has 2. Although my initial installation leaked, after re-seeding the filter it has been leak free. No noticeable charchol when I first ran water through it.  Ran about 3 gallons though to ensure all was clear.  Great tasting water, no off flavors.  Will buy again.
