[Instant Hot] Waterdrop CoreRO Reverse Osmosis System, NSF/ANSI 58 & 372 Certified, 6 Stage, Hot & Ambient Countertop RO Water Filter, No Installation Required, 3:1 Pure to Drain, WD-C1H

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.

Firstly, the majority of the exterior of the heating version(C1H) is Gray, not Black. Amazon should change their info. The non heating one (C1S) is white. Also, the Heating version does NOT include a TDS display on the panel. I bought the heating version knowing this.Where does the backwash go? It goes back into the water tank that you fill from your tap. That’s why they say you must always dump the water that is on the bottom of that tank when you refill. I dump before it gets that minimum level. So the 3:1 may be “ideal” but practically, not so. That doesn’t matter to me, it may for you. Water your plants if it bothers you.I bought a second “clean water” tank. Each tank is 1L, so once it fills, I can have one in the refrigerator. There are some nice cylindrical glass pitchers in hat you can fill directly- just make sure the height is 9-3/4” or less. I attached a picture showing unit and extra 1L tank. The 78 deg is probably my “room temp” water.I did a test, I filled up two 16 oz glass bottles from the dispenser. After the second bottle filled, It took about 80 seconds until the pump turned off. (ie I had the clean tank full of 1L of water). It takes about 50 seconds to fill a 16 oz bottle.I have it next to my Phillips coffee system so I can fill that tank directly. One picture shows display. It now defaults to 16oz, the size of my bottles, but that is easy to change.Instructions for new filter could be more clear….it took a while to get filter installed, I had to look at the connection detail to figure it out, then push and rotate firmly- I was nervous about breaking, so really wanted to be sure I did it right. Don’t worry- the entire backwash process to get a new filter takes a while, and a bit confusing and time consuming, but hopefully you will not have to do this for another 10-12 months.Do not expect to clean up raw well water with this. If you have a well with a water softener, maybe you could filter the softened water with this.I will update when I test the heating feature, and will update the rating if I have problems.

Received the waterdrop RO in a very timely manner. Instructions very easy to follow to set the filter up for first use. The water quality is fantastic. My wife loves how easy it is to use. The functionality is very nice. Once you fill the tank with the unfiltered water it does not take long for the RO to fill the container with the good RO water. So filters pretty fast and it does the automatically. We chose this counter top for the value and the size would fit under our cabinet. Plus we want the grate taste of alkalinity water. Unfortunately this product was not ship with the alkalinity filter. I contacted Waterdrop through email. I ask them if this filter was the correct filter. The Waterdrop representative from the customer service, told me that this was not the alkalinity filter that should had shipped with the product. The customer service supper nice and waterdrop has already sent me a new correct filter. What an awesome company. This is a fantastic company and a great countertop RO system.

filter doesn't have a fill detector and im not sure at how accurate the measurements are. also the filter sometimes spews into 2 streams which isn't a big deal since it doesn't stray off to far. But i can finally say that i am now hydrated since i have no excuse. GO BUY A WATER FILTER AND DRINK WATER!!!
