Waterdrop G2 Reverse Osmosis System, 7 Stage Tankless RO Water Filter System, Under Sink Water Filtration System, 400 GPD, 1:1 Pure to Drain, Reduces TDS, FCC Listed, USA Tech, WD-G2-W

I don't normally take time to do product reviews. This product has inspired me. I have had it installed for a little more than a month, and so far, it performs as described. The water is clear, clean and great! I even split the output line and ran it to my refrigerator. The almost clear ice and cold water from my dispenser is a great blessing and it gets used a lot. The installation is easy as promised. I seldom have DIY projects that I don't have to run to the hardware store one or more times. Everything that you need comes in the package and the instructions are sufficient for a reasonably handy person. The one real difficulty is mounting the provided faucet. Making the hole in your counter or sink is installation dependent. I already had a hole from a previous RO product. I had difficulty tightening the nut to secure the faucet. My mounting hole is positioned between the wall and the back of the kitchen sink. I would recommend a basin wrench if you have on available. The price of the replacement cartridges is a little high...about $140 for a 2 year period of operation. But, if the unit continues to perform, I would say that it is very much worth it. I particularly like the 1:1 efficiency of the RO. My previous unit was a terrible waste of water and made an annoying noise when it was back flushing itself. I will probably follow this review up with another when it comes time to change the first cartridge in a year.

I owned a successful marine aquarium service company for 15+ years and have been a reef tank hobbiest for more than 30 years. I know a lot about water quality, both for my reef tank water changes, and for my daily drinking water. I manufacture my aquarium water using RODI technology (reverse osmosis deionization), the only practical method for producing lab grade water with 0.0 TDS (Total Dissolved Solids). This takes constant digital testing of both my input city water and the output water after my filter. I am sure I have bored you to sleep but please WAKE Up. (In case you wonder why I don't simply drink the water from my RODI filter, one would need to add minerals back to it first before it would be safe to consume on any type of regular basis.) Now you know why I wanted a separate, dedicated Reverse Osmosis drinking water system for my family. After I Installed the Waterdrop Tankless Reverse Osmosis unit, (a very straight forward task that honestly should take the average person about 1/3rd the time of an old technology RO filter with pressurized water tank for drinking water), I was shocked to test the output water at the included metal faucet at a low TDS of just 3 PPM. My city water entering the Tankless system is currently at 140ppm. The fact that the Waterdrop system improves the water quality to only 3ppm without the use of dionization is AMAZING. Also, I turn on the filter and immediately test the water, thus there is no wait time required to let the water run before it is ready to drink. I have had my Tankless system running for months and it is rock solid at 3ppm. It is clean, delicious drinking water from an attractive, compact unit. I could not be more pleased. I also want to speak to the customer service I experienced. Unfortunately, after about 2 months of use, the 400GPD system would not turn on. I was really surprised when this occurred and emailed Waterdrop support without delay. Although I was well past the Amazon 30 day return period, the representative clearly cared about customer satisfaction and shipped me out a new, complete upgraded 600 GPD unit and a return postage paid shipping label for my original 400 GPD unit. He also sent me a free extra filter cartridge for the inconvenience I had experienced. I have had this replacement unit running for months without any issues. I would give Waterdrop 10 stars if it was allowed. Thanks for reading my lengthy, but honest review. Please buy a Waterdrop Tankless Reverse Osmosis filter, you will not be sorry you did!

I've been using this for about 4 months and I have to say it is a LIFE SAVER! We live in super low humidity and I was using 3 humidifiers 24/7 and there was this fine white dust EVERYWHERE. It took me about 6 months to figure out what was going on. Obviously buying distilled water for 3 6-gallon humidifiers would be prohibitively expensive. I bought this unit for one of our sinks and a different unit for another sink. I have to say I really like this one a ton better. The other unit utilizes a pressure tank so you can only get a little over a gallon every 30 minutes or so. Not a big deal if you are only drinking, but THIS unit is powered by a pump and you can fill up a humidifier in no time. I keep waiting for the "change filter" lights to go on, but they haven't. I am wondering if the fact that we had power cut offs in the last 4 months has somehow re-set the filter? It's hard to believe it is still functional with the amount of water we've used, but then there is no white dust coming from the humidifiers so I'm assuming it is still chugging away. This is well worth the money. I had a plumber set it up just because I didn't want to mess with it myself, but I can see how it would be a straight forward install for a handy person. Just make sure you have a plug in nearby as the unit does require electricity. Definitely recommend and would buy again!

I replaced my old Brondell Circle RO system with this Waterdrop unit, and I couldn't be happier. - ​Installation: Incredible easy. It was almost plug-and-play. I was able to reuse my old faucet and drain assembly (the tubing size was compatible). The only new part I had to install was the provided inlet tubing. ​ - DIY Friendly: Even if you aren't handy, you can do this. Save your money—no plumber needed. ​ - Performance: Water tastes crisp and clean with no odors. I considered the 3-filter model, but this one is performing perfectly. ​ - Noise: It is dead silent when dispensing water. ​ Highly recommended for anyone looking to upgrade their under-sink setup. Don't forget to wrap the white tape around the water wall outlet to avoid any leaks.

Producto con muy buena calidad de componentes, instrucciones bien detalladas y con varios videos consultables en YouTube. Una cosa que no había tenido en cuenta es el ruido que hace al funcionar (aconsejable ponerlo en mueble con puerta). Lo he comprado confiando en que el importador tendrá los recambios en breves. Como curiosidad da 25 desde, no se si es mucho o poco.

Discreto prodotto ma il problema è che dopo un po’ non sono più riuscito a contattare l’assistenza per il problema dei filtri

I have been using this unit for about 6 months now and it has held up great so far and continued to produce fresh and crisp tasting water on demand without any leaks or issues. The install was also very easy as I luckily had a hole in my granite countertop from a previous install. Although, you might need a professional to do that part for you if you dont want to ruin your countertop. I did also get a bit technical and invested in a TDS meter to test the quality of water being produced and if the RO was doing its job. After testing I noticed that when the faucet is turned on initially the TDS is high as the water which is sitting inside the unit is exited, the TDS drops after running the water for 10-15 seconds. This does result is some water wastage also meaning if you just want to fill a quick glass of water, it will not be the best quality of water that the system can produce. I did get into touch with the customer service team and they were very helpful and suggested I fill a pitcher rather than turning on the system for every glass of water required. Overall, using the pitcher method I'm getting around 10-20 PPM on the TDS meter compared to 280PPM after my softener does its job. Overall, Im satisfied with this product and will recommend it to anyone looking to install a undersink RO system. My only hope is that newer iterations can resolve the issue of the filter producing water at full efficiency right when it is turned on. My next milestone of using this product would be to replace the one of the filters as it has a 1 year life. Looking at the cost of the filters, it is a bit on the higher end but I do hope that it gives me the full year life that is stated.

Started well and does seem to produce clean water. The problem is it now rumbles (quite loudly) every two minutes as if trying to force water through the system. Cannot find any contact details for the selling company.

Excellent R/O system, very easy to install, compact and doesn’t take much space, works very well, I had 220-250 TDS after installing this system 4 TDS, highly recommended!!!
