Waterdrop Rf3375 Nsf Certified Water Filter, Replacement For Pur Rf3375, C08B Compatible Model: NSF certifications: After a series of relevant NSF tests, this Waterdrop filter has been certified to be NSF 42 and NSF 372 compliant. The NSF 42 compliance means it efficiently eliminates 97.2% of chlorine, taste, and bad odor from water, while the NSF 372 compliance means only lead-free materials are used in making this filter. Every sip of water from this filter is clean and safe. High-quality filter materials: Unlike the inferior carbon block, we have chosen natural coconut shell in making the carbon block filter. Therefore, the surface area is larger. The micropores are more, ensuring that the filter efficiently filters multiple impurities tested by a third lab, including sediment, rust, lead, and chlorine, off your water. With Waterdrop, clean, great-tasting water is never a doubt. Please note that the filter cannot reduce TDS. Perfect fit: The beauty of a filter is getting it to fit perfectly with the original faucet, alongside a flawless filtration performance like the original. The installation is seamless, and each filter cartridge ensures 3 months of filtered, crisp, and great-tasting water directly from your faucet. Remarkable flow rate: The increased number of micropores from the premium carbon block ensures that this replacement faucet filter cartridge delivers a smooth and higher flow rate. Please soak the filter in clean tap water for 3 minutes to flush the filter and release the bubbles before using Compatible models: PUR faucet systems, PUR RF-3375.
