4.5 Rating 1238 Reviews
Key Features
  • [Advanced composite filters]: The composite filter can reduce most contaminants, such as TDS and heavy metals.
  • [Innovative tankless design]: The tankless design ensures the safety of your family’s drinking water and saves over 70% more under-sink storage space than does the ordinary RO system.
  • [No waiting for clean water]: This RO system offers a fast water flow rate of up to 400 GPD. Get a cup of filtered water in about 12 seconds.
  • [Integrated product design]: The advanced integrated design of the electrical and water circuits reduces leakage. The airtight housing reduces noise, while the process of installing and replacing the filter is faster and more convenient than with other filters. Due to the filters’ twist-and-pull design, you can replace them in 3 seconds. The installation of the Waterdrop G2 RO System takes less than 30 minutes.
  • [Special notice]: An electrical outlet and drilling holes is required to operate the RO system.

  • An electrical outlet is required to operate the RO system.
  • We do not recommend connecting tankless RO to a refrigerator or ice maker.
  • We do not recommend using well water as source due to its complicated composition.
  • Placing this RO after a salt-based water softener may affect the taste (reduction rate 90%).
  • Drill two holes to install the system. One for faucet assembly and the other for drain pipe connection.
Why choose the Waterdrop Under-Sink Reverse Osmosis Water Filtration System?
New technology, new experience. Two major innovations.
The G2 RO system is 5.9 inches wide and takes up very little space under the sink. The faster and more stable water flow will produce a cup of filtered water in 12 seconds.
The RO system uses the filter composition technology with a filtration accuracy of 0.0001 μm, reducing most of the contaminants, including heavy metals, and chemical residues in tap water.
Superior accessories
Safe material provides clean water all day long.
*Automatic notification system for safer use.
*The filter life indicators automatically notify you about the service life and usage.
The RO system uses excellent lead-free plastic material. It is equipped with superior filter media that ensures effective filtration. The system also comes with a lead-free brushed nickel faucet and an easy-to-install U-shaped gasket, giving you access to clean water throughout the day.
Adopts composite filters for better filtration
Filter composition technology The new filter composition technology employs an excellent filter combination to achieve a more efficient filtration. The filters can soften water and effectively reduces most contaminants.
Activated Carbon Block Composite Filter The CF filter adopts a sediment PP membrane layer and an activated carbon block layer. It reduces common impurities such as sediment, rust, large particles, colloids, residual chlorine, fluoride, and scale.
Reverse Osmosis Membrane Composite Filter With its large filtration area, the MRO filter effectively reduces most impurities such as heavy metals, organic material, and TDS. The activated carbon block improves the taste of the output water.
Reduction contaminants list
Reduces common contaminants The RO system reduces over 90% of TDS, chlorine, bad taste, odor, chloramine, scale, and turbidity after complete flushing.
Reduces carcinogens and heavy metals Reduction of carcinogens: chromium (hexavalent), chromium (trivalent), cadmium and cadmium compounds, and ferric oxide. Reduction of heavy metals: lead, mercury, barium, copper, radium 226/228, and aluminum.
Reduces contaminants larger than 0.0001 μm The filter aperture is so fine that contaminants larger than 0.0001 μm cannot pass through the filters, including cysts.
Reduces chemical residues in water Reduction of inorganic pollutants: arsenic and inorganic arsenic compounds, fluoride. Reduction of organic pollutants: asbestos, benzene, formaldehyde, phenytoin, nitrate, nitrite, bisphenol A, trichloromethane, PFOA, etc.

Questions and Anwsers

Is Waterdrop G2 tankless reverse osmosis remove fluoride from the water?

Our RO system uses reverse osmosis filtration technology with 8 layers of MRO membranes with a pore size of 0.0001um, the system can reduce most contaminants including up to 90% of fluoride in water.

Is it safe to drink RO water?

Yes. Our G2 Reverse osmosis water filter reduces 90% of TDS and other harmful contaminants from water.

Can this RO filter be used with hard water?

Yes, but we do not recommend using it as a source for the RO system directly. During the filtration process, hard water can cause scale, making it extremely difficult for RO's membrane to work and the result is a lower quality of water.

Can I use our own faucet?

Truly sorry, the brushed nickel faucet is the only option available now.
You could use your own RO faucet with our product, but not a 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.
Secondly, your RO faucet should be able to connect with the outlet tubing of the system, which has a diameter of 1/4".
In addition, it should have a "Quick-Connect Fitting", please click here.
OR, it should come with a set of accessory parts, which allows you to connect the faucet with the bare end of our outlet tubing. Please click here to see the example for your reference.
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.

What size hole would I need to drill to install the faucet in my sink?

It's recommended to drill a hole of 1". If there's a reserved hole for the soap dispenser on your countertop, you could use that to install the RO faucet directly. In addition, we have included a sticker in the package, which could be used as a reference while drilling the hole.

What does Pure to Drain Rate mean?

The reverse osmosis water filter relies on a semi-permeable membrane to filter out impurities from drinking water. When the tap water is compressed through the RO membrane, it produced pure water and waste water. The ratio of pure water to waste water is called wastewater ratio. 1:1 wastewater ratio means 1 gallon water is wasted per 1 gallon purified, and 2:1 wastewater ratio means 1 gallon water is wasted per 2 gallon purified. The higher the wastewater ratio is, the less waster water produced during the filtration process. During the use of RO water filter, the actual ratio might be lower than the labeled, depending on many factors such as water quality, pH, pressure and temperature.
