What You Get and How It Performs

• 9-stage filtration paired with a 0.0001 μm membrane for enhanced water purity and dependable contaminant reduction.
• PFOS and PFOA reduction, along with fluoride and lead mitigation, based on SGS testing and NSF/ANSI certifications.
• Efficient water use with a 3:1 pure-to-drain ratio, which helps minimize waste compared to older RO setups.

• Two filters are pre-installed (RO + PCB) for a quicker setup and reduced install time.
• Five-year or longer RO filter life and multi-year PCB filter life simplify maintenance and planning.
• The smart faucet includes a color-changing LED to indicate when a filter swap is due, enabling proactive upkeep without guesswork.

Certifications, Performance, and Practical Use

Engineered to meet rigorous standards, the VIOMI system carries NSF/ANSI 372, 53, and 42 certifications and is SGS-tested for performance claims. Expect up to a 94.75% reduction in total dissolved solids and up to 99.60% PFOS/PFOA reduction under tested conditions, contributing to a consistent taste and clarity in drinking water and beverages.

Installation and Maintenance that Fits Your Rhythm

Note: installation requires two drilled holes—one on the countertop for the RO faucet and one under the sink for the drain line—plus access to an electrical outlet. Replacing filters is designed to be quick and tool-free: RO filters approximately every 48 months, PCB filters about every 24 months, with the faucet’s LED reminding you when it’s time to refresh.

Beyond the technical specs, this VIOMI system is built for real-life use: you can count on steady supply for hydration, meal prep, and hot beverages, with confidence that the water you pour is filtered through a multi-stage process designed to reduce a broad range of contaminants. The combination of strong filtration, space-saving design, and clear maintenance cues makes it a practical choice for households seeking reliable, high-quality tap water without the clutter of bulky equipment.
