- As an upgraded filtration system, the G2 P600 RO system has a fast water flow rate of 600 GPD. Dispensing 2 cups of pure water will produce only 1 cup of wastewater, saving 600% more water.
- With Waterdrop’s improved composite filter technology, the G2 P600 RO system can reduce most contaminants. The CF filter reduces rust, sediment, and organic matter. The MRO filter intercepts TDS, atrazine, salt, nitrates, PFAS, fluoride, heavy metals, etc.
- Waterdrop Small Water Pressure Tank is designed to unlock more functions in tankless RO systems specifically: a) Allow your tankless RO system to work perfectly with a refrigerator or ice maker, avoiding frequent reboots. b) Extend using the distance of the RO system, ensuring constant water flow or ice if there’s a long distance between the RO system and refrigerator or ice maker.

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, chloramine, lead, salt, atrazine, fluoride, nitrates, PFAS, bacteria, etc.
- Post activated carbon block: Reduces taste and odor and improves the taste of water.
- PET pleated membrane: Further filters out large particles.


WD-G2CF
- Sediment PP membrane + Activated carbon block
- Reduces sediment, rust, suspended solids, chlorine, taste and odor.
WD-G2P6MRO
- Reverse osmosis membrane + Sediment PP membrane + Activated carbon block + PET pleated membrane
- Reduces TDS, lead, salt, atrazine, fluoride, nitrates, PFAS, bacteria, etc., further filters out large particles and improves the taste of water.
Fine pore diameter
- The RO membrane has a pore diameter of 0.0001 μm, which does not allow large molecules or ions to pass through. Therefore, it can reduces most of contaminants in water.


600 GPD fast water flow
- This G2P600 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.




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.


Natural activated carbon block
- Made from Sri Lankan coconut shells, the activated carbon block efficiently removes taste and odor, thereby improving the taste of water.
- Newborns are very delicate. Compared to tap water, RO water is purer, cleaner and more suitable for babies. Milk powder made by RO water is easier to be absorbed.


- The remineralization filter can connect to all types of under sink water filter systems. By adding one filter, you can enjoy remineralized water with a refreshing taste. Please click here to purchase this add-on filter.
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.

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.
