Waterdrop G3 Reverse Osmosis Water Filtration System, one of the latest products launched last year, is an ungraded water filter system dedicated to meet your urgent need for the highest contamination removal rate with a fast water flow. RO, the abbreviation of reverse osmosis, is a “superstar” technology employed in water purification system, where partially permeable membrane is used. And we are striving for excellence to deliver the best water purifier for you. We have a series of drinking water filtration system, and G3 is one of the best. Let me tell you why choosing Waterdrop reverse osmosis drinking water filter system is one of the best decisions you will make!
For decades, we drink water directly from the faucet with no awareness of the fact that some substances in taping water are harmful to our health. Lead, for a start, is a toxic metal that comes from the pipe lines in almost every American household. Drinking lead-tainted water can lead to many problems. Once absorbed, lead will be stored in our bones as a continual internal exposure, waiting to be released as our bones demineralize. This may result in people getting possible health risks like high blood pressure, cardiovascular diseases. Children under age 3 is extremely vulnerable to it. Luckily, our ro water purifier is NSF 372 certified for lead-free material, effectively cutting off lead exposure from root. The system also got NSF 58 claim to reduce 94% of TDS, another main impurity we aim to conquer. TDS, standing for total dissolved solid, effects taste and odor of water if its level is exceedingly high. Removing TDS can give you a pure water free from unpleasant taste and odor. This is the best reverse osmosis system you can ever have!
Besides all the certifications, Waterdrop reverse osmosis filter system first uses composite ro water filter before any other in the US market. This original move brings about excellent performance in filtration. Its seven-stage filtration of the home reverse osmosis water filtration system is achieved by combining multiple best under sink water filter materials into one reverse osmosis water filter.
Water first goes through a pre-sediment PP membrane and a carbon block filter. The high-precision activated carbon block is made from natural coconut shell, the pore of the activated carbon block in which is much higher than that in other forms. This will remove sands, rusts, chlorine, etc. After running through another sediment membrane for additional impurities rejection, water will face a three-layer filter—reverse osmosis membrane, to remove 99% of TDS and heavy metals like arsenic and mercury. The efficiency equals more than three stages of filtration. Using ro membrane will give you an extra benefit—you don’t have to replace filters that frequently! The reverse osmosis filter can bring you so much convenience! With the last step of filtration through a secondary activated carbon block finished—mission accomplished! Any particles larger than 0.0001 μm will be filtered out. More than 1000 contaminants are blocked outside. There, a cup of water that is pure, healthy, absent of taste, odor and color is right in front of you.
This is what we give you—the reverse osmosis water.Bon appetit! Get you a water filtration system for home! Get you a water filtration system for home because this is the best home water filter using the best ro filter!

Does the RO system produce wastewater?

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.

What contaminants can Waterdrop RO system remove?

• 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.

Does Waterdrop RO system need power?

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

Do I need plumbing services to install the RO system?

No. 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.

How often do I need to change the filter?

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.

Does the RO system make a loud sound?

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.

Waterdrop Reverse Osmosis System

Waterdrop G3 RO water filtration system is an all-in-one, intelligent water purification system with many innovative designs. Our under sink reverse osmosis is designed to be tankless, leaving out the gigantic and ugly reverse osmosis water tanks used often in conventional water treatment systems. And this smaller and more compact reverse osmosis system can be easily put under the sink while saving more storage than its conventional counterparts, and this new water filter reverse osmosis also helps you avoid secondary pollution. This is one of the best water filter systems for home! This tankless reverse osmosis water filtration ranks high on the best home water filtration system list. Another innovative design is the internal pump, which is used for raising water pressure, and with the application of composite filter elements, the water flow of the under-sink water filter can reach to 400 GPD (gallons per day). This literally means you can get a cup of filtered water in just 12 seconds. The traditional RO system, however, filters water more slowly and stores water in the reverse osmosis tank, which may cause secondary contamination and therefore cannot meet the goal of producing purified water. This quick water purification process and tankless design meet the need of your whole family and even small companies for a purer ro water.
Besides this, Waterdrop Reverse Osmosis Water Filtration System is environmentally friendly, as it saves water waste by 300% compared with traditional home water filtration system. The waste water ratio is 1:1. There are complaints about reverse osmosis water system filtering more waste water than filtered water, but with our product, we free you from this worry. And waste water is by no mean a waste. Instead, you can use your innovation to use this water to flop floor, clean yard, or even wash car. Of course, this will also save you money on water bills. It kills two birds with one stone! Another advantage of buying our ro water system is its simple installation. It’s normal to look at countless components, having no clues about how to put them together to become one machine, let alone an enormous pure water filter such as this. But please don’t worry about that. Our filtered water dispenser is designed to be easy-to-install. Within just a few minutes, an under-sink water filtration system can be installed and put to use. But make sure that once the installation is finished, the first step is to turn on the faucet and flush the system for about half an hour. The light on the faucet will flash blue during this period time. Wait till it stops, and then you can start to use the system and enjoy the excellent water filtration. Water filter replacement is another advantage. Reverse osmosis filter replacement is also quite simple, as it can be changed with one single turn.
All in all, Waterdrop promises to give you the best home water filtration system possible, so that you and your family members can enjoy the great-tasting, pure, and healthy water. We regard having healthy drinking water as one of the most important human rights, and customers need is paramount, and we value your reverse osmosis system reviews as these are what makes us see where our problems lie and ways to help us progress! We are here to deliver the best water filtration system!
