Description

[Flexible Installation & Refrigerator Compatibility] Need purified water for your refrigerator or ice maker? Simply connect using standard tubing (not included). Just plug and play—no extra tank required. Use your own compatible faucet if preferred. Installation requires a standard outlet and two drilled holes: 1"-1.5" for the faucet, 1/4" for the drain pipe. If you have a garbage disposer, the filter requires a dedicated outlet for constant power—it cannot share the disposer’s switched outlet.

[NSF/ANSI 58 & 372] The Viomi B6W under sink water purifier meets rigorous NSF/ANSI 58 standards for reverse osmosis systems—covering contaminant reduction and structural safety—as well as NSF/ANSI 372 lead‑free material requirements. Independently tested by SGS, this water filter gives you the assurance that every glass meets the highest standards of purity for your family.

[7‑Stage Filtration System] The Viomi B6W reverse osmosis water filter features a high‑precision RO membrane for superior purity. Independently tested by SGS according to NSF/ANSI 58 standards, it is proven to reduce PFOS (>99.5%), PFOA (>99.1%), pentavalent arsenic (>99.7%), nitrate, fluoride, and other common contaminants throughout its service life. So you can trust every sip to be as clean and healthy as it should be.

[600 GPD Instant Flow + App Control] Enjoy purified water on demand—the Viomi B6W reverse osmosis purifier features a fast 600 GPD membrane that fills a 6 oz glass in just 6 seconds, even during peak usage. Monitor filter life, water quality, and consumption patterns conveniently through the Viomi app, giving you complete control and timely filter replacement reminders. Pure water, intelligently managed—so you’re always informed about your water quality and filter status.

[Efficient 2:1 Water Ratio + Zero Stagnant Water Technology] Save water and money without compromising performance. The Viomi B6W reverse osmosis system delivers an efficient 2:1 pure‑to‑drain ratio—producing 2 cups of clean water while wasting just 1 cup. Plus, with Zero Stagnant Water Technology, you get fresh RO water on demand with no concern about TDS creep, ensuring every sip is consistently pure. More clean water, lower utility bills, and total peace of mind.
