About This
- [Important Compatibility & Installation Note] This purifier works only with the included faucet—cannot connect to other faucets, refrigerators, or ice-makers. Installation requires two holes: one on the countertop for the RO faucet and a second under the sink for the drain pipe. A standard dedicated electrical outlet is required. Before buying, measure under-sink space for proper fit—allow 2.0"–3.9" rear clearance for tubing, and account for existing items like disposers, plumbing, and supplies.
- [NSF/ANSI 53, 42 & 372 Certified] The Viomi Vortex 8 Reverse Osmosis Water Filter System is rigorously tested and certified to meet NSF/ANSI standards. It is certified to reduce lead, as well as chlorine, bad taste and odor, all while meeting strict lead-free material safety requirements. Enjoy cleaner, better-tasting water with the confidence that every drop meets the highest safety standards for your whole family.
- [9-Stage Filtration System] The Viomi Reverse Osmosis water filter features a 0.0001μm membrane for superior purity. Certified to NSF/ANSI standards, it effectively reduces a wide range of contaminants including TDS, lead, fluoride, chlorine, microplastics, PFOA, and PFOS. Enjoy exceptional purity with TDS reduction of up to 90.35%, along with targeted reduction rates of PFOS >99.88% and PFOA >99.6%. The result is softer, great-tasting water that provides a reliable safeguard for your family's health and wellness.
- [800 GPD, 3:1 Pure-to-Drain] Get water on demand. The Viomi V8 RO system fills a 6oz cup in just 5 seconds, so you can drink instantly without waiting. The high flow rate also makes it ideal for washing fruits and vegetables. This system boasts an impressive 75% purification efficiency, outperforming the average 50% rate. Unlike traditional tanked systems, it achieves a 3:1 pure-to-drain ratio—meaning you get 3 cups of pure water for every 1 cup of wastewater. This not only saves you money but also reduces water waste for a more eco-friendly home.
- [Compact Tankless Design] Say goodbye to bulky tanks. Viomi V8 tankless RO system measures just 16.3"D x 5"W x 12.8"H, saving up to 65% of under-sink space—giving you valuable extra room for a garbage disposer, water softener, or cleaning supplies. Plus, tankless technology ensures water is filtered on demand, so you always enjoy fresh, pure water instead of stagnant stored water. You can complete installation in just 20 minutes using our simple 4-step video guide.
