This allows the filter cartridge to efficiently reduce chlorine, turbidity, bad taste and odor, rust, sediment, and a wide range of heavy metals. We selected BPA-free and food-grade filter housing that passed NSF 372 certification for lead-free filtration. | [Fresh taste] The 100% natural coconut shell carbon block absorbs more impurities than low-priced and mixed carbon block. Waterdrop’s refrigerator filter significantly improves the taste of drinking water to provide the best water filtration experience possible. | [Replacement reminder stickers] Expired replacement filters might cause an accumulation of pollutants and a lower level of filtration performance. Therefore, Waterdrop includes a complimentary set of monthly install stickers to remind you of your filter’s lifespan.
