Features

  • [Trusted Certification] The Waterdrop reverse osmosis system is certified against NSF 58 for TDS reduction and NSF 372 certified for lead-free material. The TDS removal rate of the RO system is certified to be up to 91.9%, and the hexavalent chromium reduction rate is certified to be up to 96.9%. The tankless reverse osmosis system is also certified by the Federal Communications Commission. Besides, it won German Red Dot Design Award 2019 and meets the EU Standards and UKCA Standards for safety.
  • [8-stage Filtration] Tested by official third-party laboratory (SGS), the RO system can effectively reduce TDS, chromium, pfas, fluoride, arsenic salt, iron, radium nitrate, calcium, particles, chloride, chlorine and heavy metals like hexavalent chromium in your tap water. And our RO system can reduce toxic chemicals such as vinyl chloride, ethylhexyl acrylate, isobutylene, ethylene glycol, monobutyl ether, according to the reverse osmosis membrane technical manual.
  • [Smart display faucet] The reverse osmosis water filtration system is built with a smart display faucet. For instance, the TDS monitor tells you the quality of your filtered water, while the filter life tracker shows how soon you need to replace your filter. So now you can enjoy an improved water-using experience and a convenient lifestyle.
  • [400 GPD&1:1 pure to drain ratio] The RO system offers faster water flow (400 gallons per day) and can filter a cup of water in about 12 seconds. Compared to traditional RO systems, the Waterdrop RO System has a low drain ratio of 1:1 and saves water waste by 300%. Save more money on your water bills!
  • [Special Notice]: You must fully turn on the faucet and flush the RO system for 30 minutes after installation. The total water capacity will be about 8. 5 gallons and the water will be undrinkable during flushing. And we highly recommend using the Waterdrop authentic RO faucet as other brands may not be compatible with your system. If you have any doubts, please reach out to our customer service before buying.
  • Three filters are included in the package. Search "WD-G3-W" for replacement filters.

  • Worth the price. Well designed and water taste is improved
Can say it is the Apple of water filters - well designed. The instructions were clear crisp and to the point. I was waiting for handyman to fix it but tired of waiting and having to deal with the strong water smell took the task in my hand and was able to fix it in one day with little accidents as I am not used to such installation. I was concerned about getting into this big ticket purchase, but am satisfied with it. Recommend. One ask is if they can provide no-touch sensor to start and stop water flow for such a elegant system. ... show more

  • Power supply bad after 3 months!
System is great, does what I needs to do. Install was pretty easy if you have all the right tools, but after three months my system stopped working. No blue ring only meant my power supply stopped working and I need to replace it. Kinda a bummer only being three months and it already went out. Tried to find a replacement but looks like I have to go directly to waterdrop. Still waiting for answer back.... ... show more

  • Excellent
Easy to install. Filters are simple to install, replace and reasonably priced. It is quiet and produces a decent flow that doesn't need a storage tank. It reduced my water hardness from 145 ppm to 2 ppm, according to both the internal TDS meter and a separate external meter. I have no complaints at this point. ... show more

  • Good system, but lousy accessory
I have been using mine for a few months now, here is my take. Overview: The G3 400 Tankless RO system looks to be well made and sturdy. Everything is well labeled, including the parts. They include everything you need with exception (keep reading) Install: Installation guide is well written with pictures. So it is pretty easy to follow along. Note that the system is tall, so measure the cabinet height under your sink to make sure it will fit. The only thing is that the included angle stop adapter valve is subpar. When connected, the water sprayed out. Not from the connection to the pipes nor tubes, but from the joints of the valve. So I had to go buy a quality valve in its place: https://www.amazon.com/dp/B003YKF2JM?psc=1&ref=ppx_yo2ov_dt_b_product_details I used this brand of valve in my prior water filtration system for over 10 years without a single leak. So it is proven. I highly recommend you to use this critical part in your install. Oh, and use those silicon plumber's tape on metal to metal connections. Other than this snafu, everything worked as they should. In my case, Instead of the included water faucet, I connect that outlet straight to my frig water line. It worked well. There is plenty of pressure for water to come out of the frig without the need of optional water tank. After all, we want tankless, right? Use: It was a pain in the buttocks to rinse the system clean, since mine is only connected to the frig water. So it took me over 45 mins to let the water flush the system and filter so that the purity level can be reached. And yes, I tested the water purity level periodically and compared it with a bottled water. It went from xxx to xx gradually. And it has been working fine for the past few months without issue. I found out that just like the tanked RO systems, this tankless system will periodically flush its system even when not in use. Weird. Final thought: Overall, I am happy with this system. After testing, the water purity do reach a level in which I am happy with. And it does take up much less space as compared to Tanked system. I only wish it would include a quality angle stop valve adapter like the one I listed. Such a vital part should not be overlooked. ... show more

  • After a year, water is toxic.
After a year, water is toxic. I got sick from drinking it. I changed filters many times and I still got sick. I was hopeful but it failed. Don’t buy!

  • Don’t buy
I ordered chrome and the spout is of brush nickel. They simply said sorry but this what we have. There are lot of other reviews that said that TDS noted on machine is much lower than TDS measured after dispensing some water. Machine showed 58 always and actual water varied between 200 and 140. I wish I had not purchased it based on others reviews ... show more

  • False advertisement. Chrome option comes with only a chrome base and a brushed nickel spout.
Even though the pictures show chrome on both the base and the spout, the chrome is ONLY ON THE BASE. I called them and they said too bad so sad. A shame we live in a world where companies can get away with false advertisement like this.
