Premium Filtration Performance
- First sediment PP membrane: Reduces rust, sediment, suspended solids, and other large particles.
- Premium activated carbon block: Reduces chlorine, organic matter, taste and odor, etc.
- Second sediment PP membrane: Reduces rust, sediment, suspended solids, and other large particles.
- 0.0001-micron high-precision reverse osmosis membrane: Reduces TDS, lead, salt, atrazine, fluoride, nitrates, PFAS, bacteria, etc.
- Post activated carbon block: Reduces taste and odor and improves the taste of water.
- Remineralization filter MNR35 adds 18 natural minerals in to water, including calcium, magnesium, sodium, potassium.


A Sip Of Nature Doesn’t Cost Much
- This reverse osmosis system comes with an external RO remineralization filter to add beneficial minerals.
- 18 natural materials are adopted to restore minerals. You will benefit from RO mineral water in the long run.
Selected Natural Minerals
This system adds beneficial essential minerals to you water by using selected natural mineral stones rather than artificial chemical materials which could release harmful chemicals.


RO Mineral Water’s Benefits
- Enhance bones: Improve bone health and help prevent diseases such as reducing post-menopausal bone density.
- Lower bad cholesterol: Lower harmful cholesterol with magnesium and potassium content.
- Promote digestion: Help digestion by increasing the amylase secretion from the pancreas with its sulfate content.
- Improve skin: Rich mineral content moisturizes the skin and delays wrinkles.
*Contents mentioned above are benefits of mineral water, not Reverse Osmosis System with remineralization.
600 GPD Fast Water Flow
This G2 P600 RO system has a water flow rate of 0.42 gal/min, which is 12x more efficient than traditional reverse osmosis systems.


2:1 Low Drain Ratio
- Dispensing 2 cups of pure water will produce only 1 cup of waste water.
- Compared to traditional RO water purifiers with a water tank, the G2P600 reverse osmosis system saves 600% more water.
Kind Notice:
- Please refer to this diagram and be informed that you need to drill a hole on your countertop to place the smart faucet (No need for this step if your countertop already has a hole).
- Besides, an adapter will be installed on your household water tubing to connect to RO system’s wastewater tubing and input water tubing.
- Electricity is required to run the RO system.
- We do not recommend using well water as source for our RO systems. We do not recommend connecting tankless RO to a refrigerator or ice maker.
- It's highly recommended to install our RO system with components provided by Waterdrop. Installing the system with any parts or accessories that are not provided by Waterdrop may cause the system to malfunction or shorten the lifetime of the system/filters.


Tankless Design
This tankless under-sink water filtration system saves 70% of under-sink space and avoids recontamination, providing you with pure and crisp water.
Smart Filter Life Reminder
This under counter water filter system has filter life indicators, which will monitor the service life in real-time and notify you to replace the filters in advance.


Integrated Design
- Compared to traditional water purifiers, the G2P600 Reverse Osmosis Water Filtration System has automatic water shut-off valves and fewer connectors, which reduces the risk of water leakage.
- This system’s noise does not exceed 55dB, which is a safe noise level for everyday life.

Pure to Drain Rate
![]() Drain ratio stands for the ratio of wastewater and purified water dispensed by a RO system. For example, the 3:1 drain ratio means it uses up a gallon of wastewater for every 3 gallons of pure water you get.
