About This

• [Important Compatibility & Installation Note] Refrigerator/Ice-Maker Connection: Enjoy purified water beyond the sink—perfect for busy kitchens. Connect the Viomi M1 to a compatible refrigerator or ice maker using standard tubing (not included) and activate "Multi-device Mode" in the app for easy setup. 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.
• [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.
• [Pure Water with Natural Mineral Taste] Unlike conventional reverse osmosis systems that remove nearly all dissolved minerals, the VIOMI Master M1 reintroduces selected naturally sourced minerals after purification, creating fresh alkaline water with a cleaner, smoother taste. Perfect for drinking, coffee, espresso, tea, baby formula, soups, and everyday cooking, it delivers the purity of reverse osmosis without the flat taste many people associate with traditional RO water. Because beneficial minerals are intentionally added back, the TDS reading will naturally be higher than standard RO water—this is expected and reflects the remineralization stage, not reduced filtration performance.
• [1000 GPD, Smart Faucet & App] Enjoy purified water on demand with the M1 alkaline water purifier, featuring an ultra-fast 1000 GPD membrane that fills an 8oz cup in just 3 seconds (100 oz/min). Fill pitchers, coffee makers, stock pots, and reusable bottles without waiting for a storage tank to refill. The HD touchscreen Smart Faucet features one-touch dispensing, live TDS readings, and filter life, while the VIOMI app monitors water usage, system status, and sends filter replacement reminders, so you'll never have to remember maintenance schedules. The PCB filter lasts up to 2 years and the RO filter up to 4 years, reducing maintenance and maximizing long-term value.
• [Removes 99%+ PFOS/PFOA, Lead & Microplastics] Cleaner water starts with advanced filtration. 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. Independently tested by SGS to deliver cleaner, better-tasting drinking water your family can enjoy with confidence.
• [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 many 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 tank-based filters thanks to its slim profile (17.1"D × 6.4"W × 15.9"H). Perfect for kitchens with garbage disposers, recycling bins, or limited under-sink storage, it leaves more room for everyday essentials while delivering fresh filtered water on demand. Allow 2.0–3.9 inches of rear clearance for tubing connections. Installation typically takes about 20 minutes with our step-by-step video guide.
