What is the difference between Waterdrop and traditional RO systems?
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 contaminants 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 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.
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.
Do I need plumbing services to install the reverse osmosis 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.
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 contaminants, including coliform and
other parasites.
Does this system eliminate or remove Atrazine?
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.
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 18.06 "* 5.6" * 17.76 ", 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.
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.
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.
