Waterdrop C1H Instant Hot Countertop RO System, No Installation Required

WOW! This is a great countertop RO system. I researched various hot-cold under counter and on counter systems and decided to go with this model and glad I did. The unit doesn’t take that much space on your counter and looks streamlined and super modern. I couldn’t really find that much info on it besides the reviews here and a couple of YouTube videos but still decided to give it a shot. Setup is super easy and does take a full twenty minutes if you stand by the machine and follow its cues. I believe I had to fill the tank twice and the machine does the rest. I had bought a tds tester before this arrived and had verified my taps tds level which was also spot on from Waterdrops website zip code analyzer. My tds was showing 147 meanwhile the water from the Core Ro was coming out under 20 ppm! The water tastes crisp and pure! No weird smells or aftertaste. I do use a single stage Waterdrop under counter filter to fill my water although these type of filters do not change the tds levels. I am actually going to be removing the single stage and upgrading it to the a 3 stage filter system just for added precaution. This will also give me way better water at my fridge which will be connected to it. It might be habit but I still find myself reaching inside the fridge for water sometimes and of course ice cubes. This will help provide overall better water from both sources. The best part of this purchase was that it eliminated me having to use my Keurig maker for hot water which I hated doing due to the water sitting there and being warm in the tank all the time. So now I get clean pure filtered room temp water virtually all day long, and I also get hot water in the morning for tea and coffee. I usually refill the tank once a day. With that said I do wish the touch screen would tell you real time tds levels but it will only flash red when high tds levels have been detected which usually means it’s time for a new filter. A word of caution with this system. When the tank needs to be refilled the screen will blink “out” do not refill the tank without first dumping the remaining water left at the bottom. That is basically your waste water and the tds levels on that water was over 500 ppm. This is definitely not really apparent at first but then a light bulb went off in my head and I realized it after I refilled my first tank. Waterdrop also claims you can void your warranty by not dumping the remains water first before refilling the tank with new tap water. One minor drawback is having to slide the system forward a little bit to remove the tank and also remove the freshwater tank since I keep it under my upper kitchen cabinets. I placed a bamboo mat under it and not it easily slides forward so problem solved. I did see some will put small appliance sliders under the appliance to make it easier as well. I would highly recommend this countertop RO system for a small family or couple. I did buy a second water tank to keep in my fridge or counter for larger volume fills. In the end it was between the Core RO and the Waterdrop under counter RO system which was significantly more expensive. I think this is a good start and best of all the system can be moved and taken anywhere.

Love this thing. The instant hot water is fantastic for making instant mushroom coffees and teas. The 40 oz clean reservoir is big enough that you don't feel like you're refilling the feed tank constantly. Maintenance is pretty easy and straightforward. Also use the water to mist reptile enclosures and water terrarium plants as the RO water leaves no spots on the glass.

We were excited to ditch water bottles and filter our own water. Unfortunately, the product we received started leaking from a random hole on the bottom as well as from the power cable. Thankfully, we caught it before it could cause damage to nearby appliances or possibly start a fire. Pre inspection of products before it is sent to the consumer would mitigate issues like this.

My family purchased the WaterDrop CoreRO system over a year ago and we love it. It's easy to use, durable, and the water tastes great. We used water test strips to compare the water before and after filtering, which helped give us confidence that the filter was doing its job. Additionally, I was SO impressed with their Customer Care Team! I reached out via email after repeatedly getting an E04 error, multiple times a day. Even though the warranty period had already expired, our customer care representative, Andrew, was able to identify the issue and provide clear instructions on how to clear scale buildup. He also sent a free replacement filter as well. After the issue was resolved, Andrew went above and beyond by sending an additional filter as a holiday gesture, since I had emailed just before Christmas. The system works perfectly now and I'm very grateful for the amazing customer service!

I really like how this filter makes my life easier with its instant hot and cold water feature. The water tastes clean, and the unit looks chic on the table, adding a modern touch to my kitchen. After about six months of use, my machine began leaking unexpectedly, but the overall design and functionality have still been impressive. The replacement unit I received has been working well so far. When I contacted customer service, I was lucky to be helped by Becky. She was incredibly patient and guided me through several troubleshooting steps to try to fix the issue. Even after a few attempts, when the problem persisted, Becky quickly arranged for a replacement machine to be shipped to me. Her professionalism, kindness, and dedication made the whole experience much easier. Thank you, Becky, for your excellent customer service!

This was a very nice, economical RO unit and it allowed us to try RO water and see if our household enjoyed it. We started using it for everything including refilling our countertop nugget ice maker so we weren't spending so much on distilled water. After about a year, the unit was still filtering perfectly but we noticed the measured water dispensing became a bit less accurate. I reached out to WaterDrop and chatted with Andrew who immediately offered to replace the unit with another one. He cross-shipped the new unit so we could keep using our old one until it arrived. I can't say enough good things about Andrew and WaterDrop as they took awesome care of us to make sure we have a working, reliable unit. What company cross-ships a brand new product without even asking for a Credit Card. I highly recommend WaterDrop and wish every company had an Andrew to help customers!

I have been using this for a couple of weeks now, before any reviews were left, as I moved into a new rental unit and wanted water filtration plus on-demand hot water. We'll see how it goes over time, but so far it has been great. It's not as convenient as a permanent installation filter, but it doesn't take up much counter space and I can take it with me. I like that you can set different temps and volumes to dispense, which means I can set my mug under it and let it fill while I walk away. It's a little noisy but nothing so bad, and I'm sensitive to sounds. It took a few fills before the filter tastes as it should. The 2 lids on the top are loose, that may bother some people but it's fine for me. The back water reservoir lifts up a little and you can pull it out, you do not have to lift it very high to undock it, so if that part is under a cabinet it's not too much trouble (depending on your cabinets), and the handle is pretty nice (ensure your hands are clean, though). However, if you want to remove the pure water tank, you must take it straight up the full length. I do so to pour the purified water into a glass jug for cold water in the fridge. My main complaint is the cord is a pain in the butt. It's long and extra heavy duty thickness, so it does not like to bend. It comes straight out of the unit on the back and good luck organizing it. Worst cord management ever. I have had another Waterdrop RO under sink unit. I have had nothing but good response from their customer service so far, even when it was my fault.

I’ve been using this product for about a year and a half, and recently I started having issues with the water tank not filling properly. Although my unit was already out of the warranty period, I decided to reach out to Waterdrop’s customer service team for help. To my surprise, they were extremely responsive and supportive. They asked me to provide some videos and photos of the issue, and based on that, their team carefully diagnosed the problem. Kimberly from the Waterdrop team guided me through a descaling process using citric acid, which successfully resolved the issue. Not only that, they also sent me a replacement filter for free, and after I shared my feedback, they even sent me a small gift. My family and I truly appreciate their help. This level of patience, professionalism, and customer care really speaks volumes about the company. I believe this kind of service greatly strengthens their reputation and keeps customers coming back. This is my personal experience, and I highly recommend reaching out to their support team if you encounter any issues—they are very patient and genuinely helpful.

Wd this countertop RO machine for almost a week. Instructions for setting up are very easy & clear…also has a QR version. As RO removes even the good minerals, I add trace mineral drops to the water. Enhances the water’s flavour. I have 4 -1 litre canning jars that I rotate and fill to keep cold in the fridge, as we like drinking cold water. The hot water feature also works well for my tea. So far, we are very pleased with our Waterdrop RO countertop machine.

I’ve had this for about 3.5 months now and it has become an absolute staple in our household. It is used multiple times everyday. I love it because of the health benefits it brings our family. After all, if you don’t use a water filter then your body is the water filter. This has a room temp setting and a hot setting. The hot is very convenient for drinking tea and it’s great to have room temp as some family members prefer drinking that temp. I prefer to drink cold water and so I keep a 1L jug in the fridge that I refill with filtered water. A feature that I totally appreciate is the removable jug from inside the machine. You lift the lid, press a release button and the whole 1L reservoir slides out. Then I pour that into my fridge jug. Very handy. Anyway, since we’ve had this for a while and love it, it is definitely worthy of a 5-star review. :)

I’ve been using the Waterdrop WD-C1H for a while now and I’m very satisfied. When I had a small issue, their customer service (especially Andrew) responded quickly and replaced the unit with no hassle. The new machine works perfectly, and they even sent me a thoughtful gift afterwards. It’s rare to see this level of care and follow-up these days — truly appreciate their support! Highly recommended product and company.

Product shows an E04 error upon first installation when flushing the filter only goes until 19% and doesn’t dispense when the blue flashing light come on. Will be returning product.

It works really well, but I honestly don't understand why all the water remaining in the tank after a flush has to be drained away instead of being reused—especially considering that at least a quarter of the water is left inside.
