Waterdrop users rave about the clean, crisp taste and health benefits of filtered water. Read their stories and see why they choose us.
Curious about how the RO filter works? Our FAQ section covers everything from filter lifespan to installation tips for clean, pure water every day.
The pure to drain ratio is 2:1, therefore, for every 2 cups of pure water you get, only 1 cup of wastewater is produced, which is much higher than the traditional RO systems.
The RO system offers faster water flow (600 gallons per day) and can filter a cup of water in about 8 seconds. Compared to traditional RO systems, the Waterdrop RO System has a low drain ratio of 2:1. Save more money on your water bills!
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, chloramine, scale, turbidity.
• Carcinogens: chromium (hexavalent), chromium (trivalent), cadmium and cadmium compounds, ferric oxide.
• Heavy metals: lead, mercury, barium, copper, radium 226/228, aluminum.
• Microorganic contaminants: cysts.
• Inorganic pollutants: arsenic and inorganic arsenic compounds, fluoride.
• Organic pollutants: asbestos, benzene, formaldehyde, trichloromethane, chlordane, PFOA & PFOS, etc.
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 installWaterdrop 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 contaminants, including coliform and other parasites.
As a benefit of the RO membrane (filtration accuracy: 0.0001μm), this system is able to reduce the atrazine from the source water. In addition, the composite filters of G3 can also reduce chlorine, fluoride, heavy metals and provide you with fresh and tasty water.
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.
If you are using well water as the source, please ensuure the feed water has been through a pre-filtration sstem.
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.
Waterdrop G3P600 reverse osmosis system is certified against NSF/ANSI 58 for TDS reduction and NSF/ANSI 372 certified for lead-free material. SeeWD-G3P600 RO system test resultsfor more.
Inlet tubing: 3/8", Outlet tubing (connect with RO faucet): 1/4", Feed water adapter: compatible with 3/8" and 1/2" water line.
