K19-H Instant Hot Countertop RO System, No Installation Required

We just got this hooked up and so far it seems amazing! Was really easy to setup and get started. Changing out the filter also is a very simple process. It holds a lot of water, which is great. The water comes out pretty quick compared to other filtering units. We have a jug we fill up and then put in fridge for cold water. The hot water feature on this is incredible, comes out immediately without having to wait for the temperature to change. Hot enough for a cup of tea. Water is crystal clear and tastes great. For anyone living in an area where you can not put one under the sink, this is a great option. Also, looks very stylish and clean on the counter.

I’ve had my water filter machine for about a year now. The water tastes clean and fresh, and it’s easy to install and maintain. After using this a few times, I noticed water dripping a little bit from the faucet tip. Except for that this works great. Recently for some reason, the machine stoped working. When I contacted customer service, they, especially Becky solved the problem in a timely manner. I was so impressed by her effort and service. Highly recommend!!

I purchased the Waterdrop K19-H countertop RO system and have been very happy with the water quality and convenience it provides. Recently, I noticed an intermittent dripping issue with my original unit. I reached out to customer service, and the experience was flawless. They promptly reviewed the video I sent, diagnosed the issue, and immediately shipped out a brand-new replacement unit along with a return label for the old one. A special shoutout to Karina from customer service, who handled my case. She was incredibly professional, proactive, and went above and beyond to ensure I was 100% satisfied with my experience. It’s rare to find a company that stands behind their product like this. Highly recommend both the product and the brand!

Don’t buy it. Malfunction slightly after one month (also the return window). Have been using it normally, following the instructions. Reached out to CS and ruled out factors but still not working…

I bought my machine in October of 2024 and I can say I still absolutely love it. I’ve only had to replace the filter one time so far and have had no issues with leakage. The hot water option is extremely convenient for making tea etc. it is durable and has lasted two moves as well. I’m shocked this appliance doesn’t have 5 stars so I had to write my own - it’s one of the best products I’ve ever bought.

I really wanted to like this countertop instant hot water purifier, and while I do enjoy some parts of it, there are definitely things that could be improved. First, the manual is a little confusing, so it took some time to figure everything out. Also, you need to refill and empty the water very frequently, which is inconvenient because the fresh-water tank and the wastewater tank are built together. Another issue is the water tank design: the level markings don’t make sense. It’s actually impossible to fill the tank up to the “max” line because the internal divider sits around the 2/3 height of the tank — so the top part isn’t fully usable at all. The machine is also quite heavy, so it’s not something you can easily move. That said, I do love the heating function. It gives you the exact temperature you want in just seconds, which is super handy for tea, coffee, and baby bottles. Overall, I’d still recommend it — but only if it’s on sale, considering the design flaws.

I have bought 3 of WD-K19 for me and my family. I like it very much. Water taste good. The customer support is also very helpful. When I changed filter, I messed up and water gets into the chip and it stopped working. I contacted the customer support, Owen helped me troubleshooting and made every effort to make sure the issue to be solved and made sure I'm happy. I wish their next generation new product could remove all plastic part though.

I purchased the Waterdrop K19-H Countertop Reverse Osmosis System to provide a pure water baseline for my freshwater betta fish aquarium. Tap water in Chicago has a high mineral content, so having a reliable RO system is an absolute game-changer when you need specific parameters for aquatic life and plants. The unit consistently outputs water testing around 11 to 18 ppm of TDS, which provides a fantastic, clean slate for my custom mineral mixing. The motorized base and the filtration system function flawlessly. However, while unboxing the unit, I found that the plastic handle on the main water reservoir tank arrived chipped and damaged. I reached out to the Waterdrop support team, and a customer service representative named Lene handled my case. She was absolutely incredible! Lene quickly helped verify my Amazon order details and fast-tracked a new shipment for the replacement tank. Her communication was friendly, prompt, and she completely resolved the issue without any hassle or stress. If you need a solid countertop RO unit for your aquariums (or just for drinking, both hot and room temperature water) and want the peace of mind that comes with genuinely stellar customer support, I highly recommend this unit. Thank you so much for your amazing help, Lene!

Good price!
