Waterdrop TSB 8 Layer Under Sink Water Filter Reduces PFAS PFOA PFOS Fluoride Chlorine Bad Taste Odor with

I’ve been really happy with the Waterdrop WD-TSA-UF system (the one sold under ASIN B0D1R9RS3S) I bought it back in January 2025 — so it’s now been nearly a year — and it’s still running smoothly. The unit has been totally leak-free and dependable, with a strong flow rate for an under-sink ultrafiltration system. Installation was straightforward: the system fit nicely under my sink alongside a garbage disposal — no special modifications needed. I’ve used similar filters before, so the set-up felt familiar and easy. Since installing it, I’ve noticed the water tastes noticeably better than regular tap (I'ma municipal water supply) — clean and fresh. The specs say it filters out microplastics as well, which gives me added confidence in the quality. On top of that, I’ve been quite impressed with Waterdrop’s customer service. Becky handled a few questions for me quickly and with good detail. Overall — dependable performance, easy installation, solid water taste, and good support — I’d recommend this filter for anyone who wants a worry-free under-sink filtration system. Becky was consistently knowledgeable and thorough when answering technical questions—especially around materials, certifications, and filtration specifics. She also handled my support request quickly and followed through on every step. Overall, both the product and the support experience have exceeded expectations. I’d confidently recommend Waterdrop based on the quality of the system and the professionalism of their customer service. Read more

After reading about several under sink kitchen water filter systems, I decided to get the WATERDROP 3 stage filter. I considered three factors: levels of filtering, cost a year to maintain the system (cost of filters), and the easiness to install. I just like the 8 stage deep filtration system. It filters all the elements most common in city water and makes the water taste great. The maintenance cost is about average for most filters — about $100 a year — so this was not an issue to me. I could had gone for another system to save me 20 dollars a year but I just felt the quality for this water filtration system was superior. Installation was very easy. The system came with all the parts needed. The installation video in Amazon was very clear and helpful, and after viewing it about three times, it only took me about 15 minutes to install it (never installed a water filter before). After the system was installed, I let the faucet of water filtered run for about 10 minutes and checked for leaks — no leaks. Then, I made a taste comparison test between the water straight from the faucet and the water from the filter. The water from the filter was so crisp, clear and very tasty. (I had filters before, so I know what clean water should taste like). Now I can make a cup of my expensive coffee and enjoy the flavor! But to me the most important issue is that I no longer have to carry those 40-bottled packages of water from the car to the house. Very satisfied with the WATERDROP 3 STAGE FILTER. Read more

This system is excellent and worth considering if you can't install a dedicated filtering system or at least use a dedicated filter faucet. I agree with previous comments about its ease of installation and the quality of the water taste; I highly recommend it. However, the suggested replacement time for the filters is inaccurate and should be around 2 to 3 months at most. Essentially, you are running all your cold water through the system, even for rinsing dishes. Naturally, this causes a drop in water pressure, but the crucial filter is No. 3. I faced significant water pressure issues within two months, replaced filter No. 1, as it was supposed to have the shortest lifespan, but there was no change. I replaced filter No. 2 a week later, but still saw no improvement. Eventually, I ordered and replaced filter No. 3, and the system returned to its original performance. Read more

I purchased this item to replace a unit that I've had for over 3 years, specifically, because it was rated to remove fluoride from my water. I was happy with my existing unit except for this one exception so I went ahead and purchased the Waterdrop unit. It was very easy to install and work perfectly for about 3 months. Then I experienced a slight rumbling noise and the water quit flowing. I immediately emailed the Waterdrop customer service and got a very quick response from Andrew, who was great to work with and very responsive and professional. After explaining the details of what happened, he walked me through a couple of troubleshooting procedures to see if we could get the unit working or figure out what was wrong. When none of these steps worked, he sent me a brand new unit to replace the defect of one, and a postage paid return shipping box for the old unit. It arrived very quickly and I had it up and running again in no time. It is rare these days to find that type of customer service with a manufacturer. I have already recommended this unit to many of family members who have the same issue with fluoride being added to municipal water. The water quality (per my water testing kit) I get is as good or better than the unit that I was happy with over 3 years that it replaced, but with no detectable fluoride. I highly recommend this unit and the Waterdrop company for any of the products they produce considering the service they provide.. Read more
