Waterdrop G3P800 RO System – 800 GPD Tankless Under-Sink, NSF Certified, 3:1 Pure to Drain, Smart LED Faucet

Meet Waterdrop G3P800: Tankless RO for modern kitchens

The Waterdrop G3P800 is a compact, tankless reverse osmosis system designed to live under your kitchen sink. It delivers purified water on demand, with a sleek faucet and quiet operation, so you can enjoy fresh-tasting water without sacrificing counter or cabinet space.

Built for busy homes, this system combines a 10-stage filtration process with advanced media to target a wide range of common contaminants and residues. The result is water that tastes clean for coffee, tea, meals, and everyday drinks, while keeping your under-sink area neat and accessible.

10-stage filtration and trusted certification

Tested by SGS and certified by IAPMO R&T to NSF/ANSI standards 42, 53, 58, and 372, the G3P800 aims to reduce chlorine, odors, and a variety of contaminants while using lead-free materials. The combination of membrane-based filtration and precision media supports consistent performance across daily use.

• 10-stage filtration targets PFAS, fluoride, heavy metals (lead, chromium, iron), nitrates, chlorides, and large particles
• Certified for reduction of taste and odor (NSF/ANSI 42 & 53) and total dissolved solids (NSF/ANSI 58)
• Lead-free materials certification (NSF/ANSI 372) for safer installation under the sink

Performance you can rely on

With an 800 GPD capacity, the G3P800 is designed to meet higher daily demands while maintaining a steady flow. The system dispenses a cup of purified water in about 5 seconds, thanks to efficient filtration and flow design. The 3:1 pure-to-drain ratio helps manage wastewater, delivering three cups of purified water for every one cup of wastewater.

• 800 GPD high capacity supports larger households or frequent use
• Fast dispense: a cup of water in roughly 5 seconds
• Efficient 3:1 pure-to-drain ratio reduces wastewater compared to many RO systems

Smart design and user-friendly features

A dedicated smart faucet provides real-time TDS and water quality information at a glance. The LED indicator remains visible for easy monitoring, and the LED light is designed to endure up to 50 years of use. The tankless design saves under-sink space and enables continuous purification without waiting for a tank to refill.

• Smart faucet with LED display for quick water quality checks
• Long-lasting LED indicator and compact, tankless footprint
• Under-sink install keeps the kitchen area tidy and safe

Why it matters for real life
