Product review (5 stars): Simple replacement water filter for our Samsung Refrigerator
Althought these filters do not have any elemental silver to hinder bacteria growth, these do have excellent activated carbon filter media to adequately remove the chlorine from your tap water.  The result is fresh and clean tasting ice and chilled water, for much less than the OEM cartridges.  Just replace them close to when the indicator notifies you, and you'll be good to go.
