Waterdrop G3 RO System 1-year Combo Sets, with Smart Display Faucet

Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to filter out impurities from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter. The result is that the solute is retained on the pressurized side of the membrane and the pure water is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores, but should allow filtered clean water to pass freely.

A reverse osmosis system reduces sediment and chlorine from water with a prefilter before it forces water through a semipermeable membrane to reduce dissolved solids. After water exits the RO membrane, it passes through a postfilter to filter the drinking water before it enters a faucet.

All RO systems will produce concentrated water to discharge impurities. Compared to traditional RO water purifiers, Waterdrop 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.

Waterdrop reverse osmosis water filter 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 contaminant.

• TDS, chlorine, taste and odor.

• harmful substances: chromium (hexavalent), chromium, ferric oxide.

• Heavy metals: lead, mercury, barium, copper, radium 226/228, aluminum.

• Microorganic harmful substances

• Inorganic harmful substances: arsenic and inorganic arsenic compounds, fluoride.

• Organic harmful substances

The RO system has a pump that will need power to maintain a fast water flow rate.

Waterdrop RO systems are designed for DIY installation. You can install the system in 30 minutes. Simply refer to the instruction manual and instructional videos, or contact us by email, phone, or live chat.

This video explains how to install Waterdrop RO system.

G3: The CF filter has a 6-month lifetime; the CB filter has a 1-year lifetime; the RO filter has a 2-year lifetime. Waterdrop G3 Reverse Osmosis System has a smart faucet and filter life indicators that will remind you to replace the filter.

The sound will not exceed 65 dB, which is a comfortable level for everyday life (65 dB is tested under standard laboratory conditions, where the feed water pressure is between 14.5 psi and 87 psi). A loud sound may be caused by the following:

a. The system is not positioned in a flat area. Make sure the system is placed smoothly without shaking.

b. The system is placed against the cabinet. Do not place the system against the cabinet. The system may vibrate when it works.

c. The water pressure is unstable. Check and confirm the water pressure is between 14.5 psi and 87 psi. The sound will decrease when the water pressure becomes stable.

The water source and power supply are not required to be cut off when the filters need to be replaced. The replacements can be directly screwed and reinstalled. RO system can be normally used after resetting and the flushing process are finished.

Our RO system uses reverse osmosis filtration technology with a filtration accuracy of 0.0001um, and the system can effectively reduce most harmful substances, including coliform and other parasites.

As a benefit of the RO membrane (filtration accuracy: 0.0001μm), this product is able to reduce the arsenic efficiently from the source water. The membrane has microscopic pores that are specially sized to allow water molecules through, while trapping larger inorganic molecules like lead, iron, chromium and arsenic.

We do not recommend using well water as source for our RO systems.
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.

As a standard appliance, this product will need to be plugged into one electrical outlet to function normally.

Yes, this model does need a drainpipe nearby, for discharging the waste water. For that, we provide an adjustable drain saddle to connect the RO's waste water tubing to your drainpipe.

In order to avoid the vibration which can affect the use experience, please ensure that there is an about 1-inch gap between the RO system and the cabinet. The size of the RO Filtration system is 18.11 "* 5.67" * 17.72 ", without a storage tank. It's very thin and takes up very little space.

Yes, our RO system has been tested and certified by NSF International. Here is the link for your reference. https://info.nsf.org/Certified/DWTU/Listings.asp?TradeName=WD-G3-W&Standard=&ProductType=&PlantState=&PlantCountry=&PlantRegion=&submit3=Search&hdModlStd=ModlStd

Inlet tubing: 3/8", Outlet tubing (connect with RO faucet): 1/4", Feed water adapter: compatible with 3/8" and 1/2" water line.

Yes, the instruction manual explains how to connect the Waterdrop to your fridge using parts purchased from a hardware store. The output from the Waterdrop to the faucet is 1/4” tubing. If your fridge has a 1/4” input, all you need is a 1/4” quick-connect T-adapter and the tubing that you’ll run to your refrigerator - you can find these online or at your local hardware store. If your refrigerator is like mine, the input is 3/8”, so I had to add an additional 1/4” to 3/8” adapter to the line leading from the T-adapter to the fridge. It doesn’t affect the performance of the Waterdrop at all.

Please note that our RO system is BPA free.

Although with filtration accuracy of 0.0001 μm, this model can reduce Calcium ion 90% of the salt from the water, the remaining salt added by the water softener may still affect the water taste. Therefore, we don't recommend placing the RO system after a salt-based water softener, since the taste will be affected.

The rated water inlet pressure of the machine is 14.5-87psi. It can work properly within this range.

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.

The life of the filter element of our machine depends on the two indexes of service time and pure water after filtration. As long as one of them reaches the upper limit, it needs to be replaced. The first stage front compound filter element is recommended to last for 6 months or to filter 550 gallons of pure water. The second stage RO element is recommended to last 24 months or to filter 2200 gallons of pure water. The third stage rear carbon rod filter is recommended to last 12 months or to filter 1,100 gallons of pure water. Due to the different water quality and water consumption of each house, the actual replacement time of the filter element is not consistent. The actual use situation shall prevail. When the filter element needs to be replaced, the prompt light on the machine and the lamp ring of the faucet will prompt through the color change. You can replace it according to the prompt, which is very convenient.

I wouldn't call it noisy at all, but you can hear it working. It is a low, vibrating sound.

The RO membrane filter needs to be changed every 24 months or 2200 gallons.

Generally speaking, the RO system can be connected to your refrigerator. After completing the registration online, you could choose the accessory kit, which will help you connect the RO to your refrigerator/ice maker. Since different refrigerator/ice maker has various requirement of water pressure, it's not possible for our RO system to provide them all. Connection under mismatched circumstance may result in many problems, including but not limited to: slow ice making, frequent start-stop issue, etc. Therefore, it's NOT recommended to connect the RO system to your refrigerator/ice maker.

Please rest assured that the RO membrane (filtration accuracy 0.0001 μm) can effectively reduceharmful substances whose diameter are greater than 0.0001 μm from the source water.

The waste to filtered water ratio is 1:1, which is much higher than the traditional RO systems.

Truly sorry, the brushed nickel faucet is the only option available now.
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.
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.
