Waterdrop TSB-ALK 8 Layer Slightly Alkaline Under Sink Water Filter System

I’ve been really impressed with the Waterdrop TSB 8 Layer Under Sink system so far. Installation was straightforward, and the instructions were clear enough that I didn’t run into any issues. Once it was set up, the difference in water quality was noticeable right away cleaner taste, no odd smell, and overall just much better than straight tap. I also like how compact the unit is. It fits neatly under the sink without taking up too much space, which was a big plus for me. The build quality feels solid, and everything connects securely with no leaks. Overall, it does exactly what it’s supposed to do and does it well. Great value for the price and definitely a worthwhile upgrade for anyone looking to improve their drinking water at home.

Buy with confidence! Let's face it, we all have better things to do than lug around flats of water bottles. And all the time having that nagging thought of where these bottles have been? Heated and cooled through the delivery - microplastics, and how many bottles have I contributed to landfills? Well, I am happy to say that making sure I have clean, filtered water is as easy as turning on the tap - just like the old days! LOL! I rested the unit on the bottom of the cabinet - easy to disengage and replace the filters. The unit was super easy to hook up. I had one unit professionally installed and one I did myself. The instructions are so straightforward. The water is even more clean-tasting (if that makes sense) than any bottled water (aside from the super expensive one in a glass - but maybe it's equal or better), it comes out cold and perfect! I had a glitch with one of the units, and had the chance to work with the Customer Service, shoutout to Kimberly and Reanne - they were responsive and walked me through the process and quickly offered a solution - including the replacement of one unit.

This Waterdrop filtration unit was the easiest to install ever!! I did it in literally 5 mins. Water tastes great, no chlorine taste or smell. Quick n easy to install hoses and unit. Went with this unit bcuz it said it removes fluoride, which Grand Rapids (MI) is notorious for. Size fit perfectly behind the sink plumbing. No effect in water flow that I can tell. I think I’m going to really like this investment!

We love our filter--our water tastes exceptionally clean and we have kicked the habit of ecologically bad disposable plastic water bottles! We bought this six months ago and with at least 10 bottles of water per week, it has already paid for itself. We bought the alkaline version--I figure if alkaline water is goo enough for Tom Brady, it's good enough for us! My son-in-law installed it in less than 30 minutes and said it was a piece of cake. Highly recommend! BTW, I have not received any kind of promotional anything for this review--I just wanted to guide people towards this great, environmentally friendly water filter.

4 stars because they should have included 90 degree adapters for better hose routing. The system works great, no leaks, easy to install. The water is nice and clear for the cats’ fountain, which is the main reason I went with this system.good enough for the cats, it’s good enough for me.

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.

Expect nearly a year of use out of this water filter. Mine developed a leak, which could have been fixed by them sending a replacement washer/screen that is specific to that adaptor. Instead the "Team" of experts sent a new adaptor that fit water hoses twice the diameter of the adaptor for my filter system. When the "Team" of experts realized they could not figure out a solution, they promised to send a new unit to replace the leaking unit. That was mid June, it is now the end of August and they no longer respond to my emails. One guy with actual knowledge of the product, could have remedied the problem from the beginning. Apparently, I got the B "Team" handling my case. Moral of the story, don't buy this product. Spend a little more on a water filter made in America. We Americans work hard for our money and we deserve better than this low quality customer service.

My municipal tap water had a distinct chlorine smell and a metallic aftertaste that made even my morning coffee taste "off." I wanted a filtration system that didn't require a separate faucet or a bulky tank taking up all my under-sink storage. The Waterdrop WD-TSA-UF system is the solution. It is an Ultra-Filtration (UF) unit, meaning it filters down to 0.01 μm. Unlike Reverse Osmosis (RO) systems, it doesn’t produce waste water and doesn't require a storage tank, making it a "direct-connect" dream for small cabinets. TECHNICAL PERFORMANCE Filtration Quality: It uses a 9-stage process to reduce chlorine, fluoride, and heavy metals while keeping beneficial minerals. The water now tastes as clean as high-end bottled brands. Flow Rate: Surprisingly fast though it does have the standard flow reduction common with these type of filters. At 1.59 GPM, I can fill a glass in about 5 seconds without the "trickle" common in many other cheap/budget filters. Build Quality: The housing is twice as thick as standard filters and has been pulse-tested at high pressure to prevent cracks or leaks. INSTALLATION & MAINTENANCE Setup: It took me exactly 15 minutes. It connects directly to your existing 3/8” or 1/2” cold water line. Filter Changes: It uses a "twist-and-lock" design. You can swap the filters in about 3 seconds without tools or turning off the main water valve. Lifespan: The filters are rated for 8,000 gallons or up to 18 months, depending on your local water quality. PROS & CONS Pros: Maintains original water pressure (mostly). No "wastewater" (eco-friendly). Removes up to 99% of chlorine and odor. Cons: Does NOT reduce TDS: If you use a TDS meter, the numbers won't drop because it keeps beneficial minerals like calcium and magnesium. Cold Water Only: Do not hook this up to your hot water line

I ordered this filter system to address an issue with our well-water smelling and tasting treated, and it’s completely resolved that issue for me! I now drink water straight from the tap and really like the added feature to make the water more alkaline, which is what we were getting from our local water dispenser when filling jugs. The instructions were very clear and all required parts are provided, and I was able to install it myself in less than 30 minutes. Highly recommended.

Ich habe den Waterdrop WD-TSB Wasserfilter ,mit dediziertem Wasserhahn seit 10 Februar 2025 in Benutzung. Der Einbau war recht einfach und auch der Einbau des T-Stücks war kein Problem.Ich musste für den Wasserhahn ein Loch in die Edelstahl Spüle bohren, was ebenfalls kein Problem darstellte. Ich bin mit der gefilterten Wasserqualität sehr zufrieden. Ich habe bis Dato noch keine Tests gemacht aber wenn ich das Trinkwasser auf verschieden Werte hin untersucht habe ändere ich dieses Review nochmal. Der Geschmack das Wassers hat sich deutlich verbessert, es ist viel weicher und hat einen sehr frischen Geschmack, was vorher ungefiltert nicht der Fall war. Wer die Sankt Leonhards Heilwässer kennt kann sich das in etwas vorstellen, das gefilterte Wasser schmeckt ähnlich, weicher, runder und einfach leckerer. Das ganze System ist recht einfach gehalten, funktioniert aber perfekt. Die 3 Filter benötigen bei mir für einen Liter Wasser 16,4 Sekunden, durch den normalen Kaltwasserhahn ungefiltert 6,3 Sekunden. Ich finde den Preis für das Gesamtsystem mit den 3 Filtern angemessen und auch der Preis für die Ersatzfilter ist Ok, wenn man bedenkt das man mit dem PP Filter(29,90€) bis zu 6 Monate, mit dem GC(29,90€) Filter bis zu 12 Monate und dem CT Filter(39,90€) bis zu 18 Monaten auskommt. Mir war ein richtiges Umkehr Osmose System momentan zu teuer und nach Recherchen, fand ich den bis Dato benutzen Brita Tisch Kannenfilter in der Filterleistung, für mich , nicht ausreichend. Wer auf seine Gesundheit achten möchte und wem eine Umkehr Osmose Anlage zu teuer ist, ist mit dem Waterdrop TSA/TSB 3fach Filter System wirklich gut beraten.

En principio bastante bien, instalación sencilla, tamaño adecuado para poco espacio y producción de agua con caudal aceptable y sabor del agua similar al de una ósmosis.

Bon produit et facile à installer
