Waterdrop X12-Alkaline Mineral pH+ Reverse Osmosis System, NSF/ANSI 42&58&372 Certified, 1200 GPD RO Water Filter, 11-Stage Filtration Tankless RO System, 3:1 Pure to Drain, UnderSink, BPA Free

This is complete overkill but it addresses the two things I hate about RO systems: - The large tank - Water dribbling out and taking forever to fill coffee pot. It is compact for what it is and fits under the sink very nicely. Makes a noise while dispensing but it isn't that bad -- the water running is about as loud. Fills my pitcher in about 20 seconds so that is great. Would 28 seconds be OK? Yea probably the 1200 would have been fine too. The bayonet style filters are a personal preference choice. It does make them more expensive to replace but they are FAR easier than the filters where you have to dis-assemble the unit to replace them. I am a little bit concerned about the longevity of the computerized dispenser. It works well but a mechanical lever would have been just fine. The quantity knob is kind of nifty but mostly a gimmick. Would be really cool if it could be pulled out and run directly into coffee pot. The dispenser is much larger than I thought looking at the pictures and leaves lots of room to fill large containers. Installation was very easy except for two things I forgot to order: 1) A drip mat. Has not leaked and I don't expect it to but I don't want to have to pull it out to replace filters. Past experience is something always drips. Maybe I over-tighten or under-tighten something, maybe I accidentally yank one of the hoses out while messing around, maybe filters drip when removing them. Better safe than sorry. 2) A proper drain connector to attach drain line to garbage disposal dishwasher line instead of drilling holes. My particular installation does not have a vertical pipe long enough to drill due to deep sink but even if it did I prefer to hook up with plumbed in connectors rather than the saddle clamp. Other than forgetting those things their claim that installation takes less than half the time as a traditional tank system are absolutely true. The hardest part was lugging bucket after bucket of water out to dump on the garden during the 35 minute flush cycle. Water tastes great (I got the alkaline re-mineralization version). My water was never horrible in the first place though -- main use is to remove salt added by water softener. Update from Spouse in case Waterdrop reads these: A great product would be even better if the base of the dispenser was slightly larger and it came with a pull-out hose similar to the sink faucet. I would love to be able to just hold it over the coffee pot.

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.

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

I am on well water. Wanted a filter that would take out lead and any contaminants. Even though my water tested fine without any filter I figured it could not hurt. In my research I found that filters that remove everything (like reverse osmosis) are not so great because your body begins to leach the minerals etc.. that’s missing from the water. (or so I’ve read) So finding a reverse osmosis system that also puts back minerals was important to me. I also wanted one that I could install myself, and one that had a high flow rate so I wasn’t standing at it all day waiting for my glass or pot to fill up. This system was easy to install, puts the minerals back in, and has the highest flow rate I could find. It also wastes about as little water as you can with a 1:1 ratio. I fill up a pitcher, put it in the fridge. I also use it to cook with. I’ve had it about 4 months now and it’s been working flawlessly.

We’ve been long-time users of the Waterdrop system and always loved the tankless design. After moving to a new house, we upgraded to the latest Waterdrop RO system. We initially had a hiccup with the faucet — it wouldn’t stop dispensing. We contacted Waterdrop support and were offered a basic replacement faucet. When we reached out to Amazon about the same issue, they replaced the entire system. Once we installed the new faucet, everything worked perfectly. The system now dispenses the exact ounces we select, the water tastes great, and it works like a charm. I no longer need to buy alkaline water — it’s available at my dispenser 24/7.

The water taste great! This is probably the most important thing for me, that the water is filtered properly and it tastes great. It was very easy to install, although I had a plumber do it as I had to remove my downpipe and get a low profile one so it would fit correctly under my sink. I would’ve given this five stars except I needed to spend an extra 39.95 as I had to buy a WD – XT pressure tank so it could connect to my fridge without the pump cycling on and off and on and off. I thought that as expensive as this unit was, it should’ve included the cold water pressure tank hook up for my fridge instead of having me purchase that separately. I do love the fact that my fridge and ice now is completely RO filtered as well. The flow is nothing short of fantastic and I love the new faucet and taste.

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!

Over all it is working really well. It is easy to install (takes some time to do the work but not too hard) if you already have the hole. The speed of filling the pot is very satisfying. The water tastes good. I think I could change back to non-mineral backfill one just by changing the F3 filter. The faucet may need to be improved. I like the function of automatically stop. But the first drop of water has too high pressure that will easily spill out. Is there a way to adjust the speed of the flow? And I have to say that I don’t like the pushing button. Is there a way to make it touch or turning? Any way, it meet all our requirements for healthy water.
