When you purchase a Samsung refrigerator with an ice and water dispenser rest assured that it is equipped with a water filtration system. Whether located inside or outside the refrigerator both filters are guaranteed to help reduce contaminants in your water. With fresh-tasting filtered water just a fingertip away you are saving by no longer purchasing water. Plus you may be helping the environment by no longer consuming water from plastic bottles. Samsung water filters are tested and certified by NSF International a non-profit non-governmental organization dedicated to public health safety and environmental protection. Its certification is widely recognized around the world as a leader in safety.
