Waterdrop G5P700A Alkaline Mineral pH+ Reverse Osmosis Water Filter, NSF/ANSI 372 Certified, 700G Reverse Osmosis System, 8 Stage RO Water Filtration System, 2:1 Pure to Drain, Smart LED Faucet

I recently installed the Waterdrop G5P700 Tankless Reverse Osmosis System, and it has absolutely exceeded my expectations.Sleek & Space-Saving DesignThe tankless design is brilliant—no bulky under-sink tank cluttering up the space. It’s compact, modern, and streamlined. Its 7-stage filtration, including a 0.0001 µm RO membrane, effectively removes PFOA, PFOS, chlorine, lead, fluoride, heavy metals, bacteria, and odors—delivering crisp, clean, and fresh-tasting water. If you're searching for a high-performance water filtration system that combines speed, efficiency, smart tech, and space-saving design—the Waterdrop G5P700 is a top-tier choice. It delivers delicious, purified water at the tap, with minimal hassle and great long-term value.

We are really happy with this RO system. The water taste is fantastic! I can’t tell anything about the installation as we hired this done. But then I did the rest of the setup which was very easy with simple instructions.The system was a little larger than I anticipated, but it did fit under our sink at an angle because we have a drain pipe at the back of the cupboard.The faucet that comes with this unit is really nice. When you turn the water on the base lights up and tells you the water levels. Pretty cool. Also when you turn on the water, the pump turns on and gives a nice steady stream of water. The pump is very quiet and not irritating at all. We have only had the system for a few weeks so haven’t had to change the filters yet.

I RARELY give anything 5 stars so it should not be taken lightly. but, this unit, the company and they're attention to service has left me totally impressed. I've had 3 previous RO units and every last one of them has left me disappointed. Some more than others but they've not been replaced because they wore out. They were hard to care for, performed poorly, Name it something left me not happy. So much so I'd actually given up on RO units and went with a simple multi-stage water filter. Which was "ok". Until this unit. For the record I also purchased one accessory for it (their small pressure tank https://www.amazon.com/dp/B09MD7FFYP?ref=ppx_yo2ov_dt_b_fed_asin_titleThis because I have the unit hooked up to my refrigerator which has an ice maker so the pressure tank was necessary so when the ice maker called for water there would be sufficient flow to maintain correct operation.Neither unit has disappointed me (except a little stand for the tank would have been nice to have). As it is I've worked around that oversight.By being a "tankless" system there is no problems with stale tasting water and being a very small tank water is exchanged in it almost immediately while it does it's job.The main unit sits under my sink, and when filling a container of say a half liter or more the pump will kick on and hum quietly under the sink. Almost unnoticeable. The water taste is great, the remineralization gives me just the right amount of TDS back into the water for taste and mineral content.Bottom line this is one helluva nice unitAlso wanted to add how incredibly attentive people in Customer Service have been especially Olivia. Honestly once again a top notch unit and company.If not this one grab a unit from these folks I don't think you will go wrong here.

I could not recommend this system more. It was very easy to install and the water quality is amazing. No drop in the water pressure and since this is the alkaline version, the water taste great flows well and there’s minimal noise.

This is a great RO system and is priced very well compared to similar filtration systems. This Waterdrop G5P700A unit was replacing an older tank RO system that we’ve owned for over 7 years and which had 4 filters. One of the reasons I selected this Waterdrop product was it only entails 2 filter replacements, but still having 8 stages of filtration. (One filter change every 6 months, and the other primary RO filter has a lifetime of 24mo).The faucet installation was the most demanding task, as needed to enlarge the hole in the granite countertop to aid in getting the faucet through. All other steps for installation were spelled out in the instruction sheet and easy to follow.I really like the black matte look on the RO unit even though it’s under my sink and not visible to everyone. The faucet which has a brushed nickel finish is an ideal match to my main kitchen faucet and the RO faucet has a very modernistic and stylish look. The electric pump that runs when the faucet handle is opened is relatively quiet. After using this system a few days you don’t even notice or are aware of the sound when the pump runs. Water stream is constant and okay, but slightly less flow than my old tank RO system. Perhaps takes another second or so to fill 8oz cup, in comparison.I’ve only had this RO unit installed and functioning for 3 months now, but everything appears to be operating great and the water taste is perfect. No issues so far with leaks or faucet dripping as other buyer reviews have mentioned. We currently are impressed with the product and hoping it will continue to operate flawlessly and provide excellent tasting water for many years to follow.** Updated review **After using this RO system for almost five months now, I'm updating my initial review. On the positive side, my independent testing with a separate third-party TDS meter confirms that the unit is providing good quality filtered water. However, a significant concern has arisen regarding the accuracy of the smart faucet's TDS display. The smart faucet consistently only displays a reading between 15 and 18, a number that does not match the actual readings I have verified using a stand-alone TDS meter.As an example: When water remains idle in the alkaline filter for an extended period (e.g overnight), the TDS will be initially higher upon dispensing. This effect holds true as my test sample with a TDS pen has been as high as 225 after inactivity. However, the TDS value in the faucet display never changes or fluctuates when turning on the faucet. In my case, the faucet display should be detecting and showing that higher mineral content, before dropping back down to a more normal range after about 15-20 seconds of purging.When I reached out to Waterdrop’s customer support about this issue, they maintained that the device was functioning "normally" and offered no solution or replacement. I believe this meaningless value on the faucet display indicates a defective sensor or faucet, and their lack of support has left me with a complete loss of confidence in the product's smart features. A properly functioning display should alert the user to any increased dissolved solids (TDS) to insure you are receiving the best quality water.
