Clean, Safe, Great-Tasting Water — Every Day, On Demand.
Say goodbye to bottled water and low-quality tap water. The Waterdrop G3P800 tankless reverse osmosis system brings pure, filtered water straight from your kitchen sink with powerful performance and advanced filtration you can trust. Designed for fast daily use and large households, this under-sink RO system delivers clean water with remarkable speed and efficiency.
Why This System Is Better Than Ordinary Filtration
Instead of relying on old-style storage tanks that take up space and risk recontamination, this tankless reverse osmosis design consistently produces fresh purified water — no waiting, no tank buildup, no compromise.
With a high daily output of up to 800 GPD (gallons per day), this system meets the demands of big families, active kitchens, or anyone who wants reliable access to safe drinking water.
Advanced 10-Stage Filtration for Maximum Purity
This isn’t a simple filter — it’s a complete purity solution. Through 10 stages of reverse osmosis and advanced media, the G3P800 significantly reduces:
Heavy metals like lead, chromium, and iron
PFAS (forever chemicals)
Fluoride and salts like chloride and nitrate
Chlorine, taste, and odor
Large particles and radioactive substances like radium
That means water that not only looks clean, but tastes cleaner, and is safer for daily drinking, cooking, and beverage preparation.
Fast Flow + Water-Saving Efficiency
Thanks to its high-flow design, this system produces water fast — filling a cup in just a few seconds so you can enjoy hydration without delay. Its advanced 3:1 pure-to-drain ratio uses water efficiently, producing three cups of filtered water for every one cup of wastewater.
This balance of performance and efficiency helps reduce waste while delivering reliable flow — no tank, no slow fill times, no frustration.
Smart Faucet With LED Water Quality Display
The included smart faucet makes it easy to monitor your water quality. Real-time display of TDS (total dissolved solids) and filter life gives you clarity and peace of mind — you always know when filters need replacement, and how clean your water truly is.
The LED indicator also ensures you don’t have to guess when maintenance is needed — everything is shown right on the faucet.
Space-Saving Tankless Design
Traditional RO systems take up significant space under your sink. This tankless model frees up storage and keeps your kitchen organized, while still delivering continuous water flow whenever you need it.
Sleek, modern, and built to last, it blends seamlessly with today’s kitchens without bulky tanks or complicated setups.

Large households or busy kitchens needing high water output
Health-conscious families who want reliable contaminant removal
People replacing bottled water to save money and reduce waste

Whether you’re filling glasses, preparing meals, or making coffee and tea, this system ensures every drop is purified and ready to enjoy.
