   My initial unit worked for about a month then started to leak. Contacted Customer Support and they (Harper) quickly sent a new one once we performed some basic troubleshooting. Water quality of the unit is much better then the fridge water. I’ve tested water quality for both and Waterdrop is hands down much better. Harper was very responsive, polite, and patient with all of our communication. I plan to purchase more units from Waterdrop in the near future, due to great product that is supported by a those who care!

   We absolutely LOVE our Waterdrop filter! The water tastes incredibly fresh and pure, and the sleek, stylish design fits perfectly in our home. The customer service is outstanding—so accommodating and helpful every step of the way. Plus, the faucet is the perfect finishing touch to our home remodel. Highly recommend!

   I purchased this for our house and the family loves it. We’ve always had a refrigerator with a filter, but this is so much better. The water tastes pure and the replacement of our first filter was easy. I was also able to do the installation myself. My parents also liked it so I purchased one for them.

   Setup was very easy and straightforward. Took about 45 mins from start to finish. Couple of small things are that this RO system won’t work without power and is all electronically controlled. The unit seems to have a little burst causing a splash at first which might be fixed with turning faucet mode on. Overall the water is great. Our tap water is about 400ppm with my tester. I just have a cheap tester so ymmv with a legit one. The RO water is between 50 and 80 ppm which in guessing is due to the remineralization process. The after tastes much better. To replace all 3 filters will cost about $220 USD. I’m hoping that our high ppm tap water doesn’t end up causing premature filter replacements, but we’ll cross that bridge when we come to it. All in all I don’t regret the purchase, but may have gotten a unit with a normal faucet in retrospect however the measuring of pours is a nice feature. I have used it extensively for water changes in our freshwater fish tank and it’s been great. I fill a 5 gallon bucket in the sink with it since it sits high it fits perfectly. Toss in an Anova sous vide set at 82 degrees and it’s pretty awesome RO solution for aquarium maintenance. Not quite sure on the filter cost over time yet but I ordered 2x of each of the cheaper filters just in case. I’ve likely used about 100 gallons so far for water changes so I’ll update after the first filter shows replacement need.

   One of the best things we’ve added in terms of household items. The water tastes great and the convenience is life changing. The water flow rate on the X-12 is surprisingly fast. We don’t ever get impatient filling up our coffee maker reserve tank, pots, large pitchers, etc.

   It’s relatively silent. When dispensing water, I only hear the water. Afterwards (the timing varies), I can hear the under sink unit draining into the pipe, but it isn’t very noticeable. The sound of the water dripping into the sink drain is louder than the unit. The lower you place the unit’s drain tube on the sink pipe, the less drip noise you’ll hear. My wife and kids don’t even notice the noise.

   I’m not that handy and was able to install myself. The instructions are helpful and I found many videos online.

   I had questions on the faucet unit. Customer service was very responsive and helpful. Top notch support along with a quality product makes this an easy five stars.

   My Waterdrop G3 stopped working at five years after replacing the RO. I reached out to customer service where Doreen was able to answer all my questions and provide a small discount on a new model. I thought that was very commendable, as my G3 was outside the warranty period. I researched all models and the X12 was the perfect choice. Upon installation and turning on the water supply, it started leaking. It then beeped continuously. I reached out to customer service and Doreen was able to send me a replacement right away! The replacement works perfectly and I’m super impressed with the quality of the unit, the quality and taste of the water, and its performance! I look forward to many years of use! My X12 is connected directly to the refrigerator, not the faucet. If you are connecting directly to a refrigerator, you will need a 3/8 to 1/4 reducer, which is not a big deal. I also recommend installing a filter bypass on your fridge, as the refrigerator filter will affect the pressure. The water pressure from the refrigerator is really good! In conclusion, Waterdrop is a great company that has excellent customer service and I could not be any happier with our new investment! Rest assured that Waterdrop will take care of its customers!

   Great RO. Super easy to install and water tastes good. Excellent investment. Still need a post install water test to confirm though.

   Overall pleased. Install was easy except the drilling into the granite part. No issue with fitment. I ran into a small problem with electrical. I only had 2 outlets under my sink. One for the diswasher and one for the garbage disposal. Didnt have a spare for the filter but since i hardly use the garbage disposal i have it unplugged for now. Keep that in mind if you plan on purchasing this filter. Would be nice if they offered this in chrome as well. Does not match my existing faucet so will need to replace it at some point. The filter head works good no issues.

   MY ONLY COMPLAINT: the water has a weird initial taste. Been using it for a few months now and it hasnt gone away. I have to run the water out of the line 1st before i fill up my glass everytime. Its initial taste is like an onion and B/O had a baby.

   Absolutely love this! We have well water and were sick of buying bottled water constantly. This has been wonderful! We bought and installed the unit back in February 2025 and have been very satisfied. I’ve been recommending it to all of my friends and family. We use it for our drinking water and in our coffee maker daily. Best purchase!

    We have been using this filter for a month, and I am pleased with its performance. I especially appreciate that you can set the faucet to dispense the desired amount of water in ounces. This is wonderful when filling a coffee pot or pitcher. I have a deep sink and it fits perfectly and doesn’t take up as much space as I anticipated.

    Love it so far – but the under the cabinet piece takes up a lot of space AND we have to call an electrician because we didn’t know there was a plug in needed for it to work. See photos for our temporary fix.
