The G3P600 maintains the exceptional performance of the G3 series while delivering impressive improvements in capacity, water flow, faucet intelligence, and pure-to-drain ratio.

The Best-Selling Tankless Reverse Osmosis Solution

Urban professionals consistently seek modern solutions to elevate their quality of life, and clean water stands at the forefront of these priorities. As you consider upgrading your home water system, the revolutionary Waterdrop X Series Reverse Osmosis Systems represent the gold standard in tankless water filtration technology.

Addressing Common US Tap Water Concerns

The saying "You don't miss the water until the well runs dry" rings especially true today. America's tap water has faced numerous safety incidents in recent years, directly impacting residents' daily lives and health.

Certified for Your Safety

  • NSF/ANSI 58 Certified: Verified for TDS (Total Dissolved Solids) reduction
  • NSF/ANSI 372 Certified: Confirmed lead-free material construction
  • Based on rigorous testing under NSF/ANSI standards 53 & 58, the G3P600 achieves up to 99% reduction of benzene, methoxychlor, and lindane. See WD-G3P600 RO system test results for complete details.

Important Installation Notes

  • Installation requires drilling a countertop hole for the smart faucet (unless your countertop already has an appropriate opening)
  • An adapter must be installed on your household water tubing to connect the RO system's wastewater and input water lines
  • Electrical connection is required for system operation
  • Well water is not recommended as a source for Waterdrop RO systems
  • The tankless RO can connect to a refrigerator or ice maker using the PMT water pressure tank
  • For optimal performance and system longevity, installation with Waterdrop-provided components is strongly recommended

FAQ

Does the reverse osmosis water filtration system produce wastewater?

All RO systems will produce concentrated water to discharge impurities. Compared to traditional RO water purifiers, Waterdrop RO system produces less concentrated water and saves 300% more water. You can collect concentrated water to mop the floor, wash your car, do laundry, etc.

What is the pure to drain ratio?

The pure to drain ratio is 2:1, therefore, for every 2 cups of pure water you get, only 1 cup of wastewater is produced, which is much higher than the traditional RO systems.

What is new about the Waterdrop G3P600 Ro water filter system?

The RO system offers faster water flow (600 gallons per day) and can filter a cup of water in about 8 seconds. Compared to traditional RO systems, the Waterdrop RO System has a low drain ratio of 2:1. Save more money on your water bills!

What is reverse osmosis water systems?

Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to filter out impurities from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter. The result is that the solute is retained on the pressurized side of the membrane and the pure water is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores, but should allow filtered clean water to pass freely.

How does a reverse osmosis system work?

A reverse osmosis system reduces sediment and chlorine from water with a prefilter before it forces water through a semipermeable membrane to reduce dissolved solids. After water exits the RO membrane, it passes through a postfilter to filter the drinking water before it enters a faucet.
