Product Description The Waterspecialist refrigerator water filter features filtration performance is comparable to the original brand. It is also certified by authority NSF 42 and 372. Far different from generic brand, Waterspecialist only adopts 100% superior coconut shell carbon block to improve taste and odor. Great filtration: Waterspecialist refrigerator filters can reduce many substances in water including chlorine, taste and odor. This has been tested and proven by an independent third-party laboratory. Premium filter material: Waterspecialist selected BPA-free and food-grade filter housing that passed NSF 372 certification for lead-free filtration. We also adopt 100% coconut shell carbon block that contains larger surface area and more micropores than inferior carbon block. Thus, the filter cartridge can efficiently reduce chlorine, bad taste and odor. Perfect fit: Waterspecialist combines precision measurement technology to produce 100% fit refrigerator filters with exquisite engineering designs, unlike inferior replacement filters that can cause water leakage issues. Also, Waterspecialist saves you time and hassle by offering tool-free refrigerator filter replacements. Fresh-tasting water: The 100% natural coconut shell carbon block absorbs more impurities than low-priced and mixed carbon block. The Waterspecialist refrigerator filter provides you a unique filtration experience. Food-grade materials: We selected BPA-free and food-grade filter housing that passed NSF 372 certification for lead-free filtration. Waterspecialist is here to protect your water safety.
