Great tasting water at your fingertips.

Rains Family FarmJanuary 28, 2026✓ Verified purchase

I finally got tired of going down to the local water station and filling up 5 gallon water jugs and broke down and bought a water filtration system for under the cabinet. I will admit, I had a little trepidation because I don’t generally like dealing with plumbing, but the installation for this system was extremely easy, and the instructions are very accurate and easy to follow. This WATERDROP unit fit very nicely under our kitchen sink. I even added a small water pressure tank as well as a mineralization filter and it didn’t take up half the space under our sink. Some things to consider when installing the system on your own or any system for that matter. You’ll need to know where your main water shut off is or at least have the ability to shut the cold water off under your sink because you will be tying into the cold water line under your sink. You’ll need an electrical outlet to plug the unit into, and you should be able to use the same one your dishwasher uses providing you have a dishwasher or garbage disposal. And a basic knowledge of plumbing will help as well but not necessary because the instructions are so easy to follow. All in all, it took me about three hours to get this installed mainly because I had to go down to the store and buy another fitting to hook up the refrigerator. We’ve had ours installed for about a month and a half to two months now and I enjoy being able to get freshwater right next to the tap at the sink. The water taste great and the filtering system seems to work very well on this unit. One thing to keep in mind, the water does not flow as fast as a regular sink faucet flows so be prepared that it takes a little bit longer to fill a glass of water up or a pitcher for example. If you think this will be a problem for you do some research and get a unit that has a faster water output. This particular unit has the digital display on the front, which will tell you when your filters need to be replaced. The manual says the filters have to be replaced every 6 to 12 months depending on the filter, but that could be different in your area based on how hard or soft your water is. As you can see from the picture below, the unit itself fits nicely underneath the sink, but all of the 1/4 inch tubing does look messy and I still need to get in there and try to make it a little neater. The tubing is somewhat rigid, so it doesn’t just lay on the bottom of your cabinet and kind of goes where it wants to go, so you may have to come up with a way to hook it to the wall or gently zip tie them together to make it a little neater. Also, it may seem like all of those plastic connectors wouldn’t work well or might fail, but honestly, once you push the tubing into those connectors, I’ve had no leaks whatsoever. Everything is nice and tight and secure. Plus it has the little blue locking rings that you put around the end of each connector to hold the tubing inside them so don’t be worried about that. All in all this is an excellent purchase and I’m really glad we got it. Having clean tasting water right from the faucet or the refrigerator is so much better than filling up ten 5 gallon water jugs twice a month. Don’t let this project seem overwhelming to you, with a few tools and the ability to read the instructions you’ll have it installed in no time. Read more

Superior product, outstanding customer service!

Calvin LeDecember 21, 2025✓ Verified purchase

This is by far the best RO system that I have ever purchased. The system looked sleek, the installation was very much plug and play. This made a huge difference compared to two previous RO systems that I owned which I always struggled to install. And best of all, the water is crisp, clean and delicious. I love the TDS reading displayed on the faucet (and also on the system) that telling when the filters need to be replaced. Drink with confidence and no more guesswork! What not to like? Lately, there was little problem with the TDS reading, I called Waterdrop customer support, within 24 hours I was contacted by Harper and she worked diligently until the issue fixed. In the end, I was given a brand new RO even though mine was out of warranty period. She also sent me two extra filters. I am very thankful for her support. The company was very very generous. They do stand by their products and delivered what promised. I was happy and strongly recommended to anyone looking for a good RO system. Read more

Great product, worth the price

Mudit AgarwalJanuary 27, 2026✓ Verified purchase

Great product, looks nice and works really well. Very easy to maintain and change the filters. It is expensive compared to the traditional tank based systems, but the modern design and easy of use does justify the additional cost. I have had this for more than a year now, and although I have had some issues, the customer support has been really great to work with me through the issues and ensuring that the issues are resolved to my satisfaction. I would like to recognize one of their customer support representative "Rosie C" through this review, who has been really helpful to resolve my issues. Read more

Water taste great! No tank a plus.

RHFebruary 19, 2026✓ Verified purchase

The unit was easy to install. The instructions for installation clear and graphics excellent. Love that it takes up less room and will be easier to replace filters. It hums, but not loud. I don't even notice it when the cabinet door is closed. The spout has the digital display to let me know when the filters need replacement. That's a plus. The water flow is great! My last one was slow. Mostly, the water taste great! I should have replaced my old system years ago. I'm hoping it will last for many years and will continue to perform as it does today. Not cheap, but as of today, well worth it. It has a 1-year warranty, however, I can't find instructions on how to submit my purchase. Read more

Equipment does the work of filtering. Easy to install. Filter bundles are available at Amazon and can be scheduled to ship in anticipation of filter changes. Customer representative Krystle was such a great help when my prior equipment broke. She was very responsive and was thorough in diagnostic. She was patient and understanding of my frustration. Good equipment and great customer representative when needed. Read more

Great product and customer service from Waterdrop

Barnabus.January 28, 2026✓ Verified purchase

Compact, effective, the water tastes amazing and this company has good customer service. Installation is straightforward and took about an hour. I bought this water filter from Amazon four years ago. It worked without issue until a month ago, when I noticed a small leak. Even though I did not buy it directly from Waterdrop, the customer service team was exceptional and patiently worked with me to replace the system with a new one at a discount. I am very happy with it and would recommend this system. Read more
