WD-C1H Instant Hot RO

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.

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!

This is a review after 6 months of daily usage. I did a lot of research before making a decision on which RO system to purchase, as I am very serious about my health. This product is superior to all other countertop RO systems on the market, as it allows you to clean and maintain all the individual reservoirs, including the reservoir where the RO water is stored after filtration, which is something that is very important and no other competitors products in this price range allow you the ability to do. Unfortunately, the handle on the feed water tank broke at one of it's hinges, making the system unusable. I contacted customer support via email, as this product comes with a one year warranty from the date of purchase. Robbie Li from customer support responded to my inquiry at lightning speed. I emailed late at night at around 1am and he responded by 3am. He kept me updated regularly throughout the entire process and got the part shipped to me within 3 days of it shipping via expedited shipping. I am very impressed by their excellent customer service and highly recommend both this product and this company. 1 FULL YEAR UPDATE: This an updated full year review of this product. After about 8 to 9 months into usage, the system started experiencing issues with overfilling. Karina in customer service was very helpful in walking me through a descaling process to try to solve the issue, but unfortunately, to no success. After attempting to fix it and failing, she was quick to send me out a brand new system, at no extra cost to me whatsoever. The product itself is still fantastic and in my opinion, still one of the best you can get on the market that is within this price range, but the customer service is even better than the product itself. I do hope that they can improve upon their design so that future models do not have this overfilling issue later on in it's lifespan, but it is still a great product! Thanks again Karina for all of the help! ANOTHER UPDATE: After about a month of daily usage with my replacement machine, it unfortunately started showing issues with it spitting water into two streams instead of one out of the dispenser while dispensing water. I contacted Karina in customer service once again about this issue, and she was very kind in sending me yet another brand new system. This system seems to be working fine, and there are no issues with it so far. I think I was just unlucky in getting a defective machine for the replacement the first time around. But I would like to thank Karina once again in helping to quickly resolve my issue and helping me to stay a satisfied customer once again!

This unit is a good size and performs well at filtering. I can’t taste a big difference in the water, but test results show it does a good job reducing TDS. I wish the water container were larger to avoid constantly removing and refilling it. We mainly use it for regular drinking water, and it runs out quickly. If you consume a moderate amount of water daily, you may want a model with a larger container or one that connects directly to a water source.

Ich habe diese Waterdrop Filter zum 2ten Mal gekauft und bin sehr zufrieden damit. Schnelle und einwandfreie Lieferung.

Me costó un poco entender cómo funcionaba (puede que sea porque las instrucciones podrían ser más específicas) pero FUNCIONA! no sé cuál era el TDS de mi agua de la llave , pero el agua que me da el purificador oscila entre 80-20 TDS que es bastante bueno, cuando el agua tiene más TDS o no se alcanza a purificar bien te avisa con una gotita roja , el agua no sabe a agua de filtro , se siente fresca y sin olor ni sabor ... Podría ser que se sintiera un poco más Mineral pero muy ligeramente, no ocupa mucho espacio y ya que le entiendes es mucho más fácil, purifica en 1-3 min unos 250 ml aprox ... Lo que me sucedió es que no había entendido que cuando queda poca agua en el tanque rellenable la tienes que desechar , yo simplemente rellenaba el tanque , entonces en automático el TDS de me elevaba bastante ... Van 10 días y nadie de mi familia se ha enfermado o quejado , me olvide de cargar garrafones, estaba preocupada porque no conocía el nivel de TDS y normalmente en la región dónde vivo en México el agua es muy pesada , pero me resultó 100% bien , purifica el agua 💧 perfecto.

Really like this countertop water filter. It comes with a container that saves the filtered clean water and the instant heat function makes life convenient!

Great water filtration system for home. Easy to use and like the preset volume setting. Water tastes good. Hope it will last in time

The filter gets stuck in the flushing step. The display shows 51% and does not advance to the next step. It makes a lot of noise and does not reach 100% to drink water normally.
