W2 Ultra integrates purification, mineralization, and multi-temperature heating in an under-sink system—delivering comprehensive healthy water solutions for modern households. Its Dual-Tank System (4.5L purified + 2.5L heated) decouples production from delivery, enabling industry-leading flow rates: 8.5L/min warm water in Turbo Mode for high-efficiency kitchen tasks, 6.3L/min ambient water for daily hydration and 4.3L/min at 45°C for immediate drinking and beverage preparation. Dual TDS probes and flow sensors power an adaptive algorithm that dynamically predicts filter life based on real water quality and usage—eliminating fixed-timer replacement. The Fresh Water Technology and dual UVC sterilization maintain freshness without user intervention. The smart faucet offers one-touch selection of 45°C, 65°C, 85°C, and 95°C, while displaying TDS values, filter life, and system status at the point of use—creating a complete "sensing–algorithm–interaction" intelligence loop. The innovative "purification followed by mineral retention" technology retains 9 types of beneficial minerals precisely during efficient filtration.
