Composite filter technology
- The new composite filter technology employs an excellent filter combination to achieve more efficient filtration.
- The composite water filters can effectively reduce most contaminants.


Composite integrated filters
- CF filter reduces rust, sediment, large particles, chlorine, taste and odor.
- MRO filter effectively reduces most contaminants, such as chloramine, antibiotics, organic matter, heavy metals, nitrite, bacteria, and limescale. This reverse osmosis water filter improves the taste of water and provides purified water that is as fresh as spring water.
Reverse osmosis membrane
- The reverse osmosis membrane has a pore size of 0.0001 μm, which is one-millionth of a strand of hair. Bacteria and viruses are 5,000 times larger than its pore size.
- Therefore, only water molecules and some beneficial mineral ions can pass through the RO membrane. Heavy metals and other impurities are discharged from the waste water tubing.
- The G2 RO membrane can reduce most of harmful substances in water.


Innovative tankless design
- The tankless reverse osmosis system ensures the safety of your family’s drinking water.
- This compact RO system also saves over 70% more under-sink storage space as compared to traditional reverse osmosis water filter systems.
- The tankless design avoids recontamination, such as bacterial growth.
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.


Fills a cup of water in 12 seconds
- This G2 Reverse Osmosis Water Filtration System offers a fast water flow rate of up to 400 GPD. Get a cup of filtered water in 12 seconds, satisfying your needs while saving time.

Smart filter life reminder
- 3 colors of lights show the status of water filters.
- Blue means your water filters are functioning well.
- Purple means you need to replace the water filter soon. You still have 15 days to replace it.
- Red means you have to replace the water filter immediately.
Easy to install
- Installing the Waterdrop G2 under sink water filtration system takes less than 30 minutes.
- Due to the twist-and-pull design, you can replace the water filter in 3 seconds.


1:1 low drain ratio
- All reverse osmosis water purification systems will produce concentrated water to discharge impurities.
- Compared to traditional RO water purifiers, the G2 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.
- 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.
How to change tankless reverse osmosis filters?
What is the PH of reverse osmosis water?
Is this reverse osmosis water filter system unit suitable for well water?
The reasons are as follows:
1. Large particles.
Compared to municipal tap water, the well water is rich of large particles, which will clog the filters easily, and shorten their lifetime significantly.Please note that the filters will still need to be replaced more frequently, even if you have added a pre-filtration system.
2. Composition
The well water has very complicated compostion, and some of them (apart from the large particles) can cause the filter or internal valve to be clogged and prevent the RO system from normal performance.
3. Water pressure
The well water may not provide the feed water pressure that the RO system requires (14.5 psi min.). Furthermore, the water pressure will be even lower after passing through pre-filtration systems.

Can I use our own faucet?
You could use your own RO faucet with our product, but not normal faucet for tap water.
There are a few things you may need to know before purchasing one:
Firstly, our faucet is equipped with a filter life indicator, which allows you to monitor the filters' life easily. If you decide not to use our original faucet, this function will not be in effect.
If the faucet does not meet one of these requirements, you will need to acquire a corresponding adapter, in order to complete the connection with the machine.
