Waterdrop TSA 8 Layer Under Sink Water Filter System, NSF/ANSI 42 Certified | Reduces PFAS, PFOA/PFOS, Fluoride, Chlorine, Bad Taste & Odor, Direct Connect to Faucet, Under Sink Water Filtration System

I searched for months for a really effective water filter to easily install, is not too expensive and doesn’t take up much space and doesn’t require me be to drill through counter or sink . This is a very good filter, only takes up space under the sink, was/is affordable. It wasn’t SUPER easy to install like the video or instruction suggests. But the main challenge is that the drain pipe and garbage disposal are in the way so it is physically difficult to get it in there, and properly connected.. imagine everyone’s under the sink set up might be different…so how easy it will be depends how how much space you have. I have a plumber in the family that installed it for me and he talked me through how to change the filter when it was time. I don’t have a natural talent for house repairs but with his guidance I can do it now.. other people might not be as challenged as I was. No leakage. No extra faucet….when turned to all the way cold it’s the filtered water. Tastes, smells and feels great. I wash my face at night in the kitchen sink because the final rinse with filtered water is noticeably cleaner and refreshing.

The Waterdrop Ultra Filtration Under Sink Water Filter System uses a 0.01 μm precision membrane, features multi-stage deep filtration, and produces zero wastewater. Installation was relatively easy. I have just finished the installation, and I ran water through the filter system for about 5 minutes. Then I drank a glass of water, and it tasted fine with no hint of chlorine. For ease of installation and initial cost I will rate this a 5 star. I can not rate long term performance or reliability.

I’ve been doing 5 gallon fog water and decided to give this a try. Took about 45 minutes to install. Water taste fantastic and I’m never gonna lift another 5 gallon water jug.

Overall, I’m very happy with this three-stage under‑sink water filter. Installation was straightforward and didn’t require anything out of the ordinary, although the included input and output pipes were a bit long for my under‑sink space. It would be great if there were an option to choose shorter pipes for tighter cabinets. That said, the filtration performance is excellent—the difference in taste is immediately noticeable, and it’s made Texas tap water genuinely pleasant to drink. Great filtration quality and value overall, with just a small improvement opportunity on fit flexibility.

I purchased this unit in 2023 and have loved how it improved the taste of our municipal water and how easy it is to maintain. For some reason, our unit developed a problem a few weeks ago and our cold water would stop in mid-stream. After going through several trouble-shooting steps that did not correct the problem, Becky, our customer service rep through Waterdrop, authorized shipment of a new unit and new replacement filters with just a small service fee. We are very happy with the customer service and products offered by Waterdrop. Highly recommend! Thanks Becky!

I just moved to a new state and the public water from our tap tastes like dirt. After installing this filter the water tastes great!! Worth every penny.

We like this water purifier, especially its strong water flow. We received a defective unit initially, but the customer service quickly replaced it with a new one, which has been working nicely so far. Although returning the defective unit was a bit inconvenient, Becky handled the issue very well. Overall, we’re happy with our experience with Waterdrop.

Works great, excellent water flow/pressure. Our city water is pretty good, so this is just enough filtering to clean it up. The flexible tubing to connect it to the supply and dispenser are a bit too stiff and take quite an effort to get it routed under the sink without interfering with everything else in there.

Product is as advertised. Level of service received from Karin is beyond extraordinary. Definitely recommend.

I recently installed the Waterdrop TSA Under Sink Water Filter System, and it has exceeded my expectations in every way. This 3-stage high-capacity water filtration system delivers pure, great-tasting water right from my kitchen sink, making it a fantastic addition to my home. Installation was straightforward, thanks to the detailed instructions and included hardware. Even with minimal DIY experience, I was able to set it up without any issues. The compact design fits neatly under the sink, taking up minimal space, which is a big plus for those with limited cabinet room. The filtration performance is exceptional. The 3-stage system effectively removes chlorine, heavy metals, and other contaminants, leaving the water clean and safe to drink. The improvement in taste and clarity is noticeable immediately. It’s reassuring to know that my family is drinking high-quality water without any harmful impurities. One of the standout features is the high-capacity filters. They last a long time before needing replacement, making the system low-maintenance and cost-effective in the long run. The easy twist-and-lock design of the filter cartridges makes changing them a breeze, further enhancing the user experience. Additionally, the water flow rate is impressive. There is no noticeable drop in pressure, even with the filtration system in place, which is often a concern with other water filters. Overall, the Waterdrop TSA Under Sink Water Filter System is a top-tier product that provides excellent filtration, ease of installation, and long-term cost savings. It’s an investment in health and convenience that I highly recommend to anyone looking to improve their home’s water quality.

Parfait, facile à installer. Le débit est légèrement réduit.

I’ve been using the Waterdrop 3-stage under-sink filter system for over a year now (in fact, I liked it so much initially that I bought the exact same system for my mother!). Recently, the water flow on my unit gradually degraded into a weak trickle. Even after replacing all three filters, the flow remained slow. I reached out to Waterdrop support and was connected with Kimberly. Kimberly provided some of the best customer service I have ever experienced. After evaluating the situation, she quickly arranged to send out a complete brand-new replacement unit. When the new unit arrived, I noticed Waterdrop had updated the hose union design with larger connectors—and once installed, the water pressure was completely restored and as strong as day one! To top it all off, Kimberly sent a follow-up "surprise" package that turned out to be a set of replacement filters. Standing behind your product with top-tier support is rare these days. Thanks to Kimberly and the Waterdrop team for going above and beyond. We will definitely continue using Waterdrop in our homes!

Ottimo prodotto, facilissimo da montare sotto il lavello. Viene sacrificata un po' di pressione, ma il risultato è buono. Acqua filtrata con deciso miglioramente del sapore e della durezza. Rapporto qualità/prezzo a mio avviso molto alto, con ca 130eur un sistema di filtrazione dell'acqua semplicissimo da montare (5/10 minuti) e dall'ottimo risultato.
