Waterdrop X12 Alkaline Mineral Reverse Osmosis System, 1200 GPD, Under-Sink

This is a high-quality well-designed user friendly RO system. The water is amazingly pure and tasty. The faucet designe is nice, firm and practical. You can specify the amount of water to dispense, so you never need to measure again, and the system indicates when it's time to change the filter. The lid of the device is magnet, and filters are easy to replace. My plumber was also admiring the design and the taste. It provides up to 1,200 gallons of fast-flow water every day. When I lived in California, I used a different water filter that was perfectly fine, but here in Nevada, the tap water is extremely hard. This system truns the water very tasty.

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 X12 1: 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.

Phenomenal RO unit. It filters water very quickly on demand so you don’t have to wait. Flow rate is high compared to other RO units. Taste is great due to the remineralization filter stage. Looks very nice and neat in the cabinet under sink. No leakage issues. Space saving without a storage tank. Big fan. Works as advertised and removes toxins from my municipal tap water.

We've been using a Culligan RO system for many years, but buying replacement filters online isn’t an option—they can only be picked up in-store. Plus, having Culligan replace the filters costs nearly $450 in California. So, we decided to switch to a new RO system that’s easier to maintain. After extensive research, we chose the Waterdrop X12. Here are the pros, cons, and some hidden features we've discovered: Pros: - Certified Water Quality: This system has passed multiple certified lab tests, so you can be confident it effectively removes contaminants. - Tankless Design: Minimizes the risk of bacterial growth (our old system had a tank, which needed periodic sanitization—costing more in maintenance). = UV Sterilization: Unlike many other RO systems with 3 filters, the X12 includes a UV sterilizing light for added protection. - Smart Monitoring: Both the faucet and main unit track when filters need to be changed—a great feature when life is already busy. - Reputable Company: Waterdrop is backed by a large company with years of experience in water filtration. This was important to us, as many RO systems on the market are from startups, and I didn’t want to invest in a system from a company that might not be around in a few years. - Award-Winning Design: The X12 won a Red Dot Design Award. Even though it’s installed under the sink, it’s nice to have something that looks great! - Excellent Customer Service: Initially, we spoke with a representative who couldn’t answer all our questions. However, we were later connected with a staff member who provided detailed responses promptly, even within 24 hours when out of the office. Cons: - Wobbly Faucet: As some reviewers noted, the smart faucet wobbles. Some have 3D-printed adapters to stabilize it. Hopefully, Waterdrop will consider adding a fix in the future. - Pricey: This is one of the more expensive tankless RO systems, but the unique features make it worth the investment. Plus, Waterdrop frequently offers discounts on their RO systems. - Noise: It does make some noise, but it’s only noticeable when the room is quiet, and it's not a dealbreaker. Additional Thoughts: Some buyers mentioned that the initial water flow is too strong, causing spills. I personally found it acceptable, as the higher flow is part of the appeal. If you prefer a slower flow, the user manual explains how to enable energy-saving mode (restart the unit and press F2+F3), which also reduces the flow. There’s another mode not mentioned in the manual called "faucet mode" (restart the unit and press F1+F2) to reduce the water flow without affecting energy use. Overall, we opted for the X12 due to its faster water flow. If you prefer a lower flow, models like the X8 or G800 might be better options. I hope this review helps you decide if the Waterdrop X12 is right for your family’s needs!

1 year ago I decided to invest in this water filter to rid our household of bottled water. Since then, we have saved tons of money by avoiding having to purchase countless cases of bottled water. Installation was a breeze. This system took us amateurs about 1hr to install including setup and cleanup. The filters last a very long time and the fact that the system indicates when you need to replace a filter. I love how it takes all the guesswork out of the process. The system overall is solid and performs well (as indicated by our TDS score whenever the water is turned on). No leaks thus far. Again, very solid build quality. If you’re looking for a high performing space-saving system, this is the product for you. Key highlights - Digital TDS water quality indicator - filter reminder - tankless and space-saving - superior build quality - changing filters is effortless - water quality is phenomenal

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.

Purchasing a $1k+ unit I assumed I was getting a high quality machine for my family. After some initial setup pains, we’ve enjoyed good tasting water for the past 6 months, hovering around 12-14 TDS. A couple weeks ago I began to receive the faucet notification to change the W2 filter. I ordered the replacement here on Amazon, with Water Drop being the official seller. Upon following instructions (shut off the water valve to the unit, depressurized the unit by turning on the faucet,etc) I swapped in the new filter. This started the automatic 5 minute flush after the filter reset was held. After, I noticed immediately my TDS jumped from the 12-15 range to the 48+ range. So I performed a few more flushes, and also let the faucet run for 30+ minutes. The TDS was unchanged, now averaging around 50. This was hard to explain because while we do have a mineralization filter on the alkaline model, that filter wasn’t touched. So why the jump in TDS? So, my family has been buying a drinking bottled water for the past few days while I wait hearing back from Water Drop support. Tired of going through dozens of plastics bottles a day, I decided to try everything again today from scratch and TDS is unchanged. Realizing maybe 50 isn’t so bad, I decided to poor myself a nice tall glass of water from the faucet at lunch. 30 minutes later, I still have a bad taste in my mouth from the water! I rinsed with bottle of water and took a drank some to make sure the bad taste wasn’t my food. Then I poured myself another glass from the faucet and horrible after taste again in my mouth. So now I have a unit that after 6 months, my family won’t even use for concerns about what containments it’s adding to the water– the opposite of what it’s supposed to do! Very very disappointed in this company and product currently.

This waterdrop filter is great. It came within a reasonable time, we were able to install it with no trouble. It has been running well. Filters are expensive, but easy to replace. Works quietly. Lets you know when filters need to be replaced. Fawcett works very well with lots of pressure.

Impressed with the product but even more with the customer service! I have the button a little crooked so sometimes would not activate when pressed, especially from one side, that being said, I contacted the customer service and I have to say it is the best one I ever reach out. I ended up receiving a free unit and free filters, still can't belive it. Faulty units can happen with any brand... but customer service like that will make me buy from them again if I have a need (this is my third reverses osmosis machine I bought in my life) and would definitely recommend this brand to anybody asking just for the peace of mind of the customer service alone. That being said love the machine too! It's a big step above the other one I tested out, way quicker, super quiet. ***other thing if you are wondering you CAN hook it up with a fridge, I was a little scared with the starting button being electronic but jut put a T connection and the unit will start when the pressure in the output drop down exactly like a less fancy one so now even my ice in my fridge have quality water :)

Extremely pleased with the Reverse Osmosis X12! Quality of the filtering unit is undeniable. We take our water from our lake which is normally yellow once out of the faucet after being filtered by our primary unit. Once going through the X12 it is cristal clear! Not too hard to install it yourself. It took approximately 2 hours. Unit is very quiet. The electronic faucet coming with the unit will fit in standard holes made on counter top. Ours is made of quartz and the faucet replaced a soap dispenser. Customer service is quick to reply to any questions or queries you have for their products.

Best purchase, no more alcalines and other minerals in my water. No more marks when boiling water too!

Great RO. Super easy to install and water tastes good. Excellent investment. Still need a post install water test to confirm though.

I’ve tried other RO systems and this one the best. Excellent Water filtration system. Installation instructions are very good, 6 months later I’m still very happy with it
