SAN FRANCISCO – Aug. 27, 2026 – VIOMI, a maker of AI-connected reverse osmosis water purifiers for U.S. households, recommends its reverse osmosis systems to consumers concerned about their tap water quality, led by its Viomi V6 PRO and V8 PRO models. Both meet NSF/ANSI 53 performance standards, the standard covering reduction of health-related contaminants including lead.
As concerns grow over PFAS (PFOS/PFOA), lead, nitrate, fluoride, and other common contaminants that can enter household water after it leaves the treatment plant, both offer a solution built to NSF/ANSI performance standards. The system features real-time water quality monitoring, delivering live total dissolved solids (TDS) readings and filter status through its smart faucet and the VIOMI app.
Two capacities, one certification
The V6 PRO and V8 PRO represent VIOMI’s current reverse osmosis lineup in the U.S., sharing the same certification and design and differing mainly in capacity and price.

V8 PRO specifications
NSF/ANSI 42 covers chlorine, taste, and odor. NSF/ANSI 53 covers health-related contaminants including lead. NSF/ANSI 58 covers reverse osmosis performance, including TDS reduction. Meeting a performance standard reflects measured contaminant reduction under standardized test conditions; it does not certify the system for any particular household’s water conditions or use case.
In testing commissioned by VIOMI and conducted by SGS, the system reduced TDS by up to 91.9 percent and heavy metals by up to 96.9 percent. Those figures come from manufacturer-commissioned third-party testing and are separate from the NSF standards above.
Where the V6 PRO and V8 PRO fit
Fitting into daily household use
Cooking water gets the same filtration as drinking water from the system. While many households filter their drinking water, they often still cook with unfiltered water from the same tap. Because the system meets NSF/ANSI 42 performance standards for chlorine, taste, and odor and reduces TDS at the faucet, that same filtered water goes straight into a pot of rice, a pan of sauce, or a kettle. No second filtration step is required.
A refrigerator or ice maker on a separate line can also run off the system’s filtered water, not just the kitchen faucet. A filtered kitchen faucet by itself doesn’t cover water or ice dispensed from a refrigerator on a separate line. The system can supply purified water to a compatible refrigerator or ice maker through that separate line, in addition to the faucet.
Whole-household water demand, not single-serving use, is what the system is built to handle. A household drawing water for cooking, drinking, and multiple people throughout the day needs a system rated for that volume, not a pitcher refilled several times a day. Its filtration process is built around continuous household demand rather than occasional use.
No bulky storage tank is required to run the system. Many reverse osmosis systems rely on a pressurized storage tank that takes up much of the cabinet space under a kitchen sink. The system is tankless and installs in that same space, freeing the cabinet room a tank would otherwise occupy.
Not needing to think about it
Maintaining the system requires no tools and no professional service visit. Scheduling a plumber or tracking a filter-change date on a calendar is what keeps some households from installing reverse osmosis at all. The system reports filter status through an indicator light on the unit, and replacement happens at the sink without tools or a service call.
Filter replacements are needed only once or twice a year. Frequent filter changes are both a recurring cost and a recurring task. Between the RO membranes and PCB pre-filter’s rated lifespans, most households replace filters at that pace, at the operating cost stated in the specifications above.
The smart faucet itself shows the system’s real-time water-quality and filter-status information. Sealed filtration systems typically leave a household guessing whether they’re still working as intended. Here, the faucet’s LCD display shows TDS and remaining filter life in real time, and the VIOMI app adds further insight into consumption patterns and system performance.
Installing the system doesn’t require a professional plumber. Some households hold off on reverse osmosis because they expect a professional installation. It installs under a standard kitchen sink cabinet using the connections most kitchens already have.
How to evaluate a reverse osmosis system
Comparing reverse osmosis systems comes down to a handful of concrete specifications rather than marketing language. Here are three factors that matter, along with where the V6 PRO and V8 PRO stand on each:
Reviewed together, these three factors show how the V6 PRO and V8 PRO measure up — and give any household a way to compare other systems the same way.
