WaterdropX12 Alkaline Mineral pH+ Reverse Osmosis System, NSF/ANSI 58 & 372 Certified, 1200 GPD Fast Flow RO Water Filter, 11-Stage Filtration Tankless RO System, 3:1 Pure to Drain, Under Sink

I would like to start Thanking WaterDrop Manufacturing an Excellent system which looks sophisticated on CounterTop, Compact in nature and most importantly good water supply that tastes excellent. I used to have older system that came with water softener(Dupure) and it is good cannot say great since it is my first RO system and did NOT know the difference. After 5 years of paying a ton of money for filters and to replace them them additional fee for the technician, I finally gave up the thought of spending close to $500 to replace the filters as my water line(RO) is NOT giving me any water. Other weird thing is I need to fill in Air in the reserve tank every Winter, if not the water does NOT come out faster enough.What I think is great about this system X121: It has 2 Modes Energy saving which saves power for me as it runs on electricity, regular mode which I can use during a family gathering where lot of water need to be pumped in less time.2: The display shows what is your water impurities as the water flows out, it is usually for me 19 to 21 which is the best possible water you can drink.3: Compact design gets under the sink occupying less space.4: You can set the amount of water that should be dispensed every time, this is an amazing feature if you have kids and sometimes dont pay attention to turn off the water.5: Changing Filters is a breeze and dont need to pay the Technician $150. Also you need to schedule and stay home for the repair.6: Most importantly the Customer Service, they are amazing and I will NOT be able to say how much they helped in installing the system and questions I have to make the system up and running.In my case I have to involve a Plumber to replace the Old system with X12 as our old system has complex installation. But there a videos and manual that can be followed easily to setup the system. For now I am Happy I made the move and water tastes like water should.Caution: If used to drinking tap water initial days you can feel it is different and this is because your taste buds are used to a taste and anything different you may NOT like it and body takes time to adjust.I posted the review to help others who delay things like me and wasting money trying to keep the old system running and not sure which system to move to. In my case this is the Best decision, everybody has different budgets so pick a system based on your needs. Also Waterdrop occasionally has deals on the systems, so subscribe or visit their website to save some more money.

Hubby was dreading this install and then said it was fairly easy and quick when done. All told, maybe an hour - I cleaned the bathroom and scrubbed down the shower and tub while he did it. He was fearing the task of drilling a hole for the faucet on our metal sink, but for nothing as it was only a hole an inch in size.He was most troubled by where to put the saddle drain as manual said on vertical pipe before the trap and we googled to find vertical OR horizontal before the trap was ok. Dishwasher drain takes up room and then our sink has deeper than usual part that goes into the pipe from the drain hole, so limited spots to choose from. I made him angle it up high I don't want anything catching that drain line to go back in and contaminate the entire system and I know there are times when water bubbles at the opening of the second sink (on the right) when the plug is pulled on the left and that could contaminate it.Good quality fittings and hose included. Wish I had pulled the filters out to check what they were like before starting it up but I didn't. It was about as loud as the dishwasher (which is fairly quite really) while it ran its 35 minute flush cycle. That is what it does on initial startup then you can use it. Haven't noticed any noise since.I like the digital display on the faucet top and I love that you dial in the quantity of water you want then press the button to let 'er flow. During the flush it just seemed to trickle out but later on it got better and releases a decent stream now. The tap can be swung from side to side and we played around first to decide where we wanted it due to the swing factor. Nice to swing completely out of the sink way in some cases so we installed it so it could swing to the right out of the way and to the left it stops just past the mid sink point I believe manual says 120 degree swing.It also shows you the TDS value while flowing out the tap but I'm not sure if it is percent or PPM have to find out. Our water is from a well and has high TDS anyway. Although it says a pre-filter should be installed for systems on well water, ours is not yet- next weekend he's adding that at the point where the water line comes into the house. Don't want to go through filters more than necessary and we know from experience that is exactly what happens with the RO systems. We've had 2 others in our past, and they had a pre-filter installed just on the line going into them, not whole house. They cannot compare to the volume this promises and without a storage tank!I am so happy not to deal with another storage tank and to have good drinking and cooking water at the press of a button, just so easy! I surely appreciate the UV treatment too as bacteria is a concern.

Setup was very easy and straightforward. Took about 45 mins from start to finish.Couple of small things are that this RO system won't work without power and is all electronically controlled. The unit seems to have a little burst causing a splash at first which might be fixed with turning faucet mode on.Overall the water is great. Our tap water is about 400ppm with my tester. I just have a cheap tester so ymmv with a legit one. The RO water is between 50 and 80 ppm which in guessing is due to the remineralization process. The after tastes much better.To replace all 3 filters will cost about $220 USD. I'm hoping that our high ppm tap water doesn't end up causing premature filter replacements, but we'll cross that bridge when we come to it.All in all I don't regret the purchase, but may have gotten a unit with a normal faucet in retrospect however the measuring of pours is a nice feature.I have used it extensively for water changes in our freshwater fish tank and it's been great. I fill a 5 gallon bucket in the sink with it since it sits high it fits perfectly. Toss in an Anova sous vide set at 82 degrees and it's pretty awesome RO solution for aquarium maintenance. Not quite sure on the filter cost over time yet but I ordered 2x of each of the cheaper filters just in case. I've likely used about 100 gallons so far for water changes so I'll update after the first filter shows replacement need.

I recently installed the Waterdrop X12 Reverse Osmosis System in my kitchen. Be warned: it’s huge and definitely on the expensive side but not especially so for an 11-stage reverse osmosis filtration system.This isn’t just a quick DIY fix; it’s a serious setup that may not be suitable for apartments unless you have your landlord's permission—especially in older buildings like mine. In my case, the landlord had his plumber complete the installation for me to ensure everything was done correctly.One of the standout features is the incredible 1200 GPD fast flow. No more waiting around for water—this system provides instant hydration, which is a huge plus for busy households. The filtration process is thorough, with a robust 0.0001μm RO membrane that effectively reduces TDS, chlorine, fluoride, lead, and more. Plus, the LED light adds a nice touch, assuring you that your water is safe to drink.I love that this system infuses healthy alkaline minerals like calcium and magnesium, adjusting the pH to an optimal level. Not only does this enhance the taste of the water, but it also promotes better health—what’s not to love?The smart digital faucet is a nice touch too. It shows TDS levels and filter life, making it easy to keep track of your water quality. The sleek, tankless design saves space under the sink, which is a bonus in my kitchen - but again, the system is by no means small, you should definitely compare your available space with the dimensions of the system.As for maintenance, the replacement filters are reasonably priced and last for a good amount of time, which makes keeping this system running smoothly less of a hassle. Plus, the eco-friendly 3:1 pure-to-drain water ratio is a great way to conserve water resources.Overall, the Waterdrop X12 is a solid investment for anyone serious about upgrading their water filtration system. Just be prepared for the installation process and the commitment it entails, especially if you’re in an apartment setting. Once it’s set up, you’ll be well on your way to enjoying clean, delicious water at home!

Easy to install and takes up less space than traditional RO systems. I really like the high flow rate, it fills a glass really quickly and tastes great. It’s also really cool that you can set an amount in ounces and it turns off when done.
