Why choose a reverse osmosis water filter system for home?
Waterdrop G3 Reverse Osmosis Water Filtration System, one of the
latest home water filter system launched last year, is an ungraded
water filter system dedicated to meet your urgent need for the
highest harmful substances reduction 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
right water purifier for you. We have a series of drinking water
filtration system, and Waterdrop G3 RO system is a tankless under
sink RO system. 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 91.9%
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. Waterdrop G3 Reverse Osmosis
desalination is above 90%. This is the reverse osmosis system you
can ever have!
Besides all the certifications, Waterdrop reverse osmosis
filtration system uses composite RO water filter. 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 under sink water filter materials
into one reverse osmosis water filter.
How does a reverse osmosis water filter system work
?
Water first goes through a pre-sediment PP membrane and a carbon
block filter. The high-precision activated carbon block is made from
coconut shell, the pore of the activated carbon block in which is
much higher than that in other forms. This will reduce sands, rusts,
chlorine, etc. After running through another sediment membrane for
additional impurities rejection, water will face a multi-stage
composite filter design with reverse osmosis system—reverse osmosis
membrane, to reduce 91.9% 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. it reduces most of the harmful substances and includes TDS
reduction. 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. Get you a water
filtration system for home because this is the home water filter
using the RO filter!
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 a tankless RO
system, 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. This is the water filter systems for home! The
tankless reverse osmosis water filter system review is high on the
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, 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 G3 RO 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 right home water
filter 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 right water
filtration system!

What is reverse osmosis water systems?
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.
How does a reverse osmosis system work?
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.
Does the reverse osmosis water filtration 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 harmful substances can Waterdrop reverse osmosis water filter system remove?
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 substances.
• 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
Does Waterdrop reverse osmosis water filter system need power?
The RO system has a pump that will need power to maintain a fast water
flow rate.
How to install reverse osmosis system?
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.
How often do I need to change the RO 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 reverse osmosis 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.
When you change filters, do you need to turn the water off?
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.
Does the RO system remove coliform and other parasites?
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.
Does this RO water system remove arsenic?
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.
Is this reverse osmosis water filter system unit suitable for well water?
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.

Do you need to have an electrical outlet under your sink for this work?
As a standard appliance, this product will need to be plugged into one
electrical outlet to function normally.
Does this RO system need a drain piping nearby for discharge?
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.
What is the amount of space required between the RO unit and the cabinet?
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.
Has this RO water system been NSF certified yet?
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
Is the water line hose 1/4" or 3/8"?
Inlet tubing: 3/8", Outlet tubing (connect with RO faucet): 1/4", Feed
water adapter: compatible with 3/8" and 1/2" water line.
Can I buy the accessory kit so that I can hook up my fridge all at once?
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.
Is this reverse osmosis water system BPA free?
Please note that our RO system is BPA free.
Does this reduce or remove the salt in the water from my water softener?
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.
What is the minimum water pressure to operate this unit?
The rated water inlet pressure of the machine is 14.5-87psi. It can work
properly within this range.
What size hole would I need to drill to install the faucet in my sink?
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.
How often do you need to replace the reverse osmosis filters?
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.
Can the system be connected with a UV water sterilizer?
Yes, it can be connected with a UV water sterilizer, and it requires an
extra power plug (the UV water sterilizer requires extra power).
How often do you have to change the membrane?
The RO membrane filter needs to be changed every 24 months or 2200
gallons.
Can the system be connected to the refrigerator so the ice is filter as well?
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.
Does this reverse osmosis water system prevent harmful substances from growing in the filter?
Please rest assured that the RO membrane (filtration accuracy 0.0001 μm)
can effectively reduce impurities whose diameter is greater than 0.0001
μm from the source water.
What is the waste water to filtered water ratio?
The waste to filtered water ratio is 1:1, which is much higher than the
traditional RO systems.
Can I use our own faucet?
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.

What does Pure to Drain Rate mean?
The reverse osmosis water filter relies on a semi-permeable membrane
to filter out impurities from drinking water. When the tap water is
compressed through the RO membrane, it produced pure water and waste
water. The ratio of pure water to waste water is called wastewater
ratio. 1:1 wastewater ratio means 1 gallon water is wasted per 1
gallon purified, and 2:1 wastewater ratio means 1 gallon water is
wasted per 2 gallon purified. The higher the wastewater ratio is, the
less waster water produced during the filtration process. During the
use of RO water filter, the actual ratio might be lower than the
labeled, depending on many factors such as water quality, pH, pressure
and temperature.
At Waterdrop, we know that access to clean and safe drinking water is
essential for everyone's health and well-being. That's why we are
committed to providing you with affordable and dependable options for
your water filtration needs.
