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.
Waterdrop is your reliable water solution.
We work hard to meet your needs, and we take feedback from every customer seriously. We are open to your suggestions and would like to help you solve problems.
*If you use well water as the source, please ensure that the feed water is pre-filtered.
*An electrical outlet is required to operate the RO system.
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.

Innovative composite filter
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 reduce most contaminants in the tap water.
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 and odor, chloramine, scale, and turbidity.
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.

Love it
Best money I have spent in a long time. Pretty simply to install, and we love the results
Best water
Probably the healthiest water we have at home. The taste is fresh, the quality is great. My plants love it too.
Easy install!!
It is working perfectly.
The water tastes so good!
My husband was at a friends house and he recommended this filtration system. I started notice that our local water was tasting very chemically, so we decided to make the purchase, and I have no regrets. The taste of the water is soo good! My husband is a plumber by trade, so he had no real issues with installation. This was one of the things that I never knew I needed in life!
Nice Product - Compact - Easy Installation
I love this unit. It was easy to install and generates an adequate amount of filtered water upon request. The compact design is the size of a small computer hard drive. In the past I had the tank RO system and found the expense of replacing filters yearly would pay for a new tankless unit in no time and the space it took under my cabinet was horrendous.. It emits a small amount of noise when dispensing, but nothing too bothersome. I would buy this unit again in a heartbeat.
