What is reverse osmosis water filtration system for home?
How does a reverse osmosis water purifier work?
What does reverse osmosis water filtration system remove?
Is this reverse osmosis water filter system unit suitable for well water?
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.

Can I use our own faucet?
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.


Premium filtration performance
- First sediment PP membrane: Reduces rust, sediment, suspended solids, and other large particles.
- Premium activated carbon block: Reduces chlorine, organic matter, taste and odor, etc. Second sediment PP membrane: Reduces rust, sediment, suspended solids, and other large particles.
- 0.0001-micron high-precision reverse osmosis membrane: Reduces TDS, lead, salt, atrazine, fluoride, nitrates, PFAS, bacteria, etc.
- Post activated carbon block: Reduces taste and odor and improves the taste of water.
- PET pleated membrane: Further filters out large particles.


WD-G2CF
- Sediment PP membrane + Activated carbon block
- Reduces sediment, rust, suspended solids, chlorine, taste and odor.
WD-G2P6MRO
- Reverse osmosis membrane + Sediment PP membrane + Activated carbon block + PET pleated membrane
- Reduces TDS, lead, salt, atrazine, fluoride, nitrates, PFAS, bacteria, etc., further filters out large particles and improves the taste of water.
Fine pore diameter
- The RO membrane has a pore diameter of 0.0001 μm, which does not allow large molecules or ions to pass through. Therefore, it can reduces most of contaminants in water.


600 GPD fast water flow
- This G2P600 RO system has a water flow rate of 0.42 gal/min, which is 12x more efficient than traditional reverse osmosis systems.
2:1 low drain ratio
- Dispensing 2 cups of pure water will produce only 1 cup of waste water.
- Compared to traditional RO water purifiers with a water tank, the G2P600 reverse osmosis system saves 600% more water.


Kind notice:
- Please refer to this diagram and be informed that you need to drill a hole on your countertop to place the smart faucet (No need for this step if your countertop already has a hole).
- Besides, an adapter will be installed on your household water tubing to connect to RO system’s wastewater tubing and input water tubing.
- Electricity is required to run the RO system.
- If you are using well water, we recommend applying a pre-filter (5-10 μm).Placing this RO after a salt-based water softener may affect the taste (reduce rate 90%)We do not recommend connecting tankless RO to a refrigerator or ice maker.
Upgraded reverse osmosis system
- With Waterdrop’s improved water purification technology, the G2P600 RO system can meet the water needs of large families and even small businesses.


Tankless design
- This tankless under-sink water filtration system saves 70% of under-sink space and avoids recontamination, providing you with pure and crisp water.
Smart filter life reminder
- This under counter water filter system has filter life indicators, which will monitor the service life in real-time and notify you to replace the filters in advance.


Integrated design
- Compared to traditional water purifiers, the G2P600 Reverse Osmosis Water Filtration System has automatic water shut-off valves and fewer connectors, which reduces the risk of water leakage.
- This system’s noise does not exceed 55dB, which is a safe noise level for everyday life.
Natural activated carbon block
- Made from Sri Lankan coconut shells, the activated carbon block efficiently removes taste and odor, thereby improving the taste of water.


- Newborns are very delicate. Compared to tap water, RO water is purer, cleaner and more suitable for babies. Milk powder made by RO water is easier to be absorbed.

Easy install
I installed it and thought there was a problem. I called tech support and they walked me through some troubleshooting and it worked. I feel ****** because there was no problem. When I plugged it in, I plugged it into the garbage disposal outlet. Guess what, there is no power until you turn on the switch! I moved it to the dishwasher plug and works great. The water tastes great and from what I can hear in the drain, the waste water is minimal.

Great invention
Amazing results with the quality of water. I am getting a TDS of 15 from the new faucet, my sink tap was about 70. I am adding a water drop mineralizer to the system this week. This system G2P600 with the little mini pressure tank from water drop powers three water faucets and two refrigerators w/ ice makers no problem. I also added the UV LED sanitizing light...what a great invention! I really like that you get a 2:1 ratio on the backwash so you're not wasting a ton of water. This really is great system, I have had it for a couple of months now. It has saved my back and wallet from many trip s to Costco to buy heavy cases of water. When I drink water from restaurants now, I can barley stand it compared to my home system...its drastically better than public or even bottled water.....all in I have about $650-ish in the system with all supplies and it's worth every penny.

Awesome
This RO system has been great. My bf installed it within 15 minutes, it was super easy. He has the traditional RO system at his house but he was impressed at how easy this install was and how it barely takes up space under the sink. The fill speed is quick and it's nice that the water doesn't get warm/room temp from sitting in a reservoir tank.

Just installed, loving it
First off, I needed to buy a 1" drill bit to make a new hole in my counter. The description made that clear, so I was able to get it delivered on the same day as this unit. Drilling the hole was pretty easy. Installation of this was really easy too. I bought the mineral filter separately to add into the system. That was an easy install too. I installed this system under my sink, where I have a recirculating pump installed to help get hot water without wasting it. Working everything in with existing plumbing was simple. Fortunately, when I run the water circulating-- it isn't back-feeding with the R/O system, and isn't kicking on the pump. My source water was measuring 513 TDS. After a simple filter at the fridge, it came down to 510 TDS. A Brita filter brings it to 509 TDS. Our water here (non-well water), is SUPER high in calcium. With this R/O + remineralisation filter, the water is coming out at 37 TDS. Purified 5 gallon bottles of water we were getting come up at 19 TDS. That is an amazing difference, and absolutely worth the money. I already cancelled our ReadyRefresh delivery service. I highly recommend the remineralisation filter if you will be using this for drinking water long term-- as far as I know, it's not healthy to drink ultra purified water long term. The water off this system tastes like the Nestle purified water we'd been getting delivered. Very happy. It was also nice they included just enough "extra" clips to lock in the hosing. The mineral filter didn't include any. I suspect the extra clips were in case customers break them while installing, but after installing everything plus the separate mineral filter, I ended up with one extra large and one small locking clip.

Dropped TDS PPM from 201 to 16
That’s a lot of total dissolved solids removed. Easy to install too. Curious how long it’ll last- we shall see.
