Product Details
✓[𝐑𝐞𝐝𝐮𝐜𝐞𝐬 𝟗𝟔.𝟒% 𝐈𝐫𝐨𝐧, 𝟗𝟖.𝟐% 𝐌𝐚𝐧𝐠𝐚𝐧𝐞𝐬𝐞 & 𝐂𝐡𝐥𝐨𝐫𝐢𝐧𝐞] This 10"" × 4.5"" two-stage whole house water filter combines an iron and manganese reduction filter with natural coconut shell GAC. Third-party tested to reduce up to 96.4% of iron, 98.2% of manganese, and 95.63% of chlorine, it also helps reduce rust, sediment, and particles larger than 5 microns for cleaner, better-tasting water.
✓[𝐅𝐨𝐫 𝐌𝐮𝐧𝐢𝐜𝐢𝐩𝐚𝐥 𝐚𝐧𝐝 𝐖𝐞𝐥𝐥 𝐖𝐚𝐭𝐞𝐫] Suitable for both municipal and well water sources, this dual-stage Waterdrop whole house water filter helps reduce iron and manganese ions, along with select heavy metals such as mercury, lead, cadmium, chromium, and copper.
✓[𝐔𝐩 𝐭𝐨 𝟏𝟓 𝐆𝐏𝐌 𝐇𝐢𝐠𝐡 𝐅𝐥𝐨𝐰] Equipped with standard 1"" NPT inlet and outlet ports, this Waterdrop whole house water filter delivers a flow rate of up to 15 gallons per minute. It helps maintain steady water pressure when showers, faucets, and other water-using appliances are running simultaneously.
✓[𝐌𝐞𝐞𝐭𝐬 𝐍𝐒𝐅/𝐀𝐍𝐒𝐈 𝟑𝟕𝟐 𝐋𝐞𝐚𝐝-𝐅𝐫𝐞𝐞 𝐒𝐭𝐚𝐧𝐝𝐚𝐫𝐝𝐬] Both cartridges in this Waterdrop whole house water filter system meet NSF/ANSI 372 lead-free standards, helping provide safer water for your family’s everyday use.
✓[𝟓𝟎,𝟎𝟎𝟎 𝐆𝐚𝐥𝐥𝐨𝐧𝐬 𝐨𝐫 𝟔 𝐌𝐨𝐧𝐭𝐡𝐬] Both filters provide up to 50,000 gallons of filtration or 6 months of use, helping reduce replacement frequency, ongoing maintenance, and long-term operating costs. Actual filter life may vary depending on source-water quality and usage.
✓[𝐂𝐨𝐦𝐩𝐥𝐢𝐚𝐧𝐭 𝐚𝐧𝐝 𝐒𝐚𝐟𝐞 𝐅𝐢𝐥𝐭𝐞𝐫 𝐌𝐞𝐝𝐢𝐚] The iron and manganese reduction media meets NSF/ANSI 372, 61, 42, 44, 53, and 58 standards, as well as FDA, RoHS, REACH, and Japan’s Food Sanitation Act requirements. It is free from PBTs, BPA, and mercury. The second-stage filter media also meets NSF/ANSI 372 and 42 standards and complies with RoHS requirements.
✓[𝐑𝐞𝐢𝐧𝐟𝐨𝐫𝐜𝐞𝐝 𝐋𝐞𝐚𝐤-𝐑𝐞𝐬𝐢𝐬𝐭𝐚𝐧𝐭 𝐃𝐞𝐬𝐢𝐠𝐧] Reinforced brass threads and two high-sealing O-rings help minimize leaks and provide a secure connection. The system has also passed more than 100,000 water hammer cycles and pressure testing under typical U.S. household water pressure for dependable, long-lasting performance.
