Standard system = Full Reverse Osmosis (RO) System including 2 standard filters.

With Extra Mineral optionFull Reverse Osmosis (RO) System including 2 standard filters + one additional "MNR" mineralization filter (installed within the water lines, between the system and the faucet).

  • With Waterdrop’s improved water purification technology, the G2P600 RO system can meet the water needs of large families and even small businesses.
  • Waterdrop reverse osmosis water filtration system adopts advanced composite filter technology. Uses the characteristics of various filter materials skillfully and combines them to achieve better filtration. The composite filter can intercept most harmful contaminants.
  • 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 waste water, saving 600% more water.
  • This tankless design saves 70% of your under-sink space and prevents recontamination.
  • The advanced integrated electrical and water circuits reduce leakage.
  • The lead-free faucet is made of food grade copper-zinc alloy with a brushed nickel plating.
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.
  • PET pleated membrane: Further filters out large particles.
Filter Stage 1 (WD-G2CF)
  • Sediment PP membrane + Activated carbon block
  • Reduces sediment, rust, suspended solids, chlorine, taste and odor.

Filter Stage 2 (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.

Upgraded reverse osmosis system

  • With Waterdrop’s improved water purification technology, the G2P600 RO system can meet the water needs of large families and even small businesses.

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.

  • Please refer to the 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 Waterdrop RO systems. We do not recommend connecting tankless RO to a refrigerator or ice maker.

Comfortable with water quality using this RO filter

Although the unit was bigger than I expected, it fit very well. We had a plumber install and he had no trouble!Water tastes great. No need to be buying all those plastic bottles anymore!

Easy install, taste great

Replaced and older multi stage RO unit with this product. Installation was super easy and we now have much more space under Our sink without having the tank and the filters are a1000 times easier to replace. Water flow on the new unit is only slightly less than on the old unit with the tank. Just realize that this requires an electrical outlet under your sink for plugging in unit. I just used a three outlet expander and plugged this unit into the same outlet as the dishwasher.

As good as it can get for now......

First and foremost the water is great. I use it for partial water changes for aquarium as well as drinking for human consumption. My tap water is a mess. The RO water is clean, clean, clean. pH at 6.0 so have to address that for the fish but not for us. Coffee tastes great. Iced tea tastes great. Water tastes great.Install a breeze. While it had the adapter I was able to use, my plumbing is the smaller 1/4 thread at the water supply. Had to put the RO adapter in between two extensions that had the larger female ends. Works fine, just if didn't have the extra extension already woulda had some plumbing figuring to do....Only issue I had with installation is the base unit kept falling over. Doesn't when installed. Its not unstable. Its base is not designed to be sliding it all over the place. Which you have to do some when installing.Why not 5 stars? Flow rate. Its not fast. at the same time it is not slow either. Its not a trickle. But its not fast. At this juncture in term of the technology 600GPD with 2:1 ratio is probably as good as flow is gonna get with tank-less design. Its not like there's something wrong. If I want higher flow from faucet would have to use tank system, etc.Glad I bought it. Going to get filters now just to be sure I have them. I have a whole house filter prior to a softener so the water getting to the RO isn't full of stuff. Still will need to replace filters at some point and want to make sure I have them on hand.I could not recommend anything less than 600GPD for tank-less because of the flow rate at the faucet.

Excellent system. G2600. Great water and easy pezy install

Love this system 100%. 30 minutes to install including drilling the hole in the sink. Did the initial 30 minute flush and everyone has been using it since. Taste is great. We were given an expensive coffee machine and where we live the water is hard so we did not want to use that in it. Have been filling 5 gallon jugs at the water stations for years but that was mostly for just drinking not coffee machine. This system stopped that. The water flow from the faucet is great. Faucet looks like a little brother to our faucet. Great system and would recommend to all..

Space saving, affordable, easy to install, and high output RO system.

I am an average DIY person and found this very easy to install. The main features I loved about this product were the space savings under the sink, the ease of installation, the speed at which great quality water is produced, and the very helpful customer service from the manufacturer I received prior to my purchase. The flavor was wonderful and I was able to reduce my TDS from 300 ppm to around 8 ppm. I would highly recommend getting the 600 gpd system over the 400 gpd system because the difference of around $50 will be worth it if you use it for anything other than drinking water (filling humidifiers, watering indoor plants, etc). I used it in an older humidifier and it actually helped to remove some of the hard water scale which had built up over time. I used to use a ZeroWater pitcher, but this is much more convenient and will save money over the long run.One thing to note is this is a tankless system, so that is where the majority of the space savings come from. It is also priced well in comparison to other RO systems.I would highly recommend this system if you are searching for an easy to install, space saving, and fast RO system.
