Master M1 Mineral Tankless Under Sink Reverse Osmosis Alkaline Water Purifier

• [Important Compatibility & Installation Note]Installation Requirements: The system requires a standard electrical outlet and two drilled holes—a 1″-1.5″ hole for the dedicated smart faucet and a 1/4″ hole for the drain pipe. If you have a garbage disposer, the filter needs its own dedicated outlet for constant power—it cannot share the switched outlet typically used for the disposer.
• Refrigerator/Ice-Maker Connection: Need filtered water for multiple purposes? The Viomi M1 can be connected to your refrigerator or ice maker, supplying purified water to a separate line. Simply connect using a separate pipe (not included) and activate “Multi-device Mode” in the App—it’s easy and effortless.
• [NSF/ANSI 42, 58 & 372 Certified] The Viomi M1 RO Alkaline Water Filter System is tested and certified against NSF/ANSI standards. It is NSF/ANSI 58 certified for TDS reduction, NSF/ANSI 42 certified to reduce chlorine, bad taste, and odor, and NSF/ANSI 372 certified for lead-free material safety. Enjoy cleaner, better-tasting alkaline water with confidence in every drop.
• [Industry-Leading Remineralization Technology] Unlike standard RO systems that strip away healthy minerals, the Viomi M1 reverse osmosis alkaline water filter adds them back. It infuses water with natural minerals harvested from deep underground, using a high-temperature process (2192°F) to simulate volcanic ion exchange. This restores essential minerals for better-tasting, alkaline water. Note: Your faucet’s TDS reading will be slightly higher than standard RO water due to these beneficial minerals.
• [1000 GPD, Smart Faucet & App] Enjoy instant pure water with the Viomi M1 reverse osmosis alkaline purifier, featuring an ultra-fast 1000 GPD membrane. Fill a cup in just 3 seconds (100 oz/min) with no waiting—even during peak usage. The HD touchscreen smart faucet offers one-touch dispensing and real-time TDS display, while the Wi-Fi App provides deeper insights into water consumption and quality. Plus, intelligent filter life monitoring tracks the long-life PCB filter (2 years) and RO membrane (4 years)—an industry-best lifespan that maximizes value and minimizes long-term maintenance costs.
• [Removes 99%+ PFOS/PFOA, Lead & Microplastics] Peace of mind starts with pure water. The Viomi M1 9-stage reverse osmosis filtration features a 0.0001-micron precision membrane, effectively reducing Total Dissolved Solids (TDS) by up to 90.56%. It targets specific contaminants with high efficiency, including lead (>99.87%), PFOS (>99.67%), PFOA (>99.42%), chlorine, and microplastics. Tested by official third-party laboratory (SGS) to ensure your family drinks the cleanest water possible.
• [Eco-Friendly 3:1 Pure-to-Drain] Save water without sacrificing performance. The Viomi M1 achieves an efficient 3:1 pure-to-drain ratio—delivering 3 cups of clean water for every 1 cup of waste. That’s an impressive 75% water efficiency, while traditional RO systems waste 2-3 gallons for every gallon purified. You get more clean water while using less, saving both water and money on utility bills.
• [Space-Saving Tankless Design] Free up your under-sink cabinet with this compact reverse osmosis system—designed to take up 65% less space than traditional tank-based filters thanks to its slim profile (17.1″D x 6.4″W x 15.9″H) that fits in most kitchen cabinets, and installation is a breeze with our simple 4-step video guide that gets you up and running in about 20 minutes.
