Makes the water so much better
Got this to replace a small generic version which used the tube shaped filters similar to those in a fridge water dispenser. The small ones only lasted a short time and seemed to be of variable quality so I replaced with this one. Easy to fit (I did need my box of parts to get the right connectors though) only took a short time to do. I cut in a shut off valve at the same time and had to cut out a section of pipe where the quick fit connector of the old system was as it used the pipe puncture type connection (not sure what the real name is!) so I took that off and replaced the section that had the hole. Water quality seems very good, flow is much faster that the old one, taste is improved as we live in a hard water area and the water can sometimes taste "dry" due to the chalk. the filter looks easy to replace, just a twist off, twist on and says it should last for 15 months which, although more expensive, is good compared to the 3 months of the others. the cost of replacement looks to be slightly more than 5 of the other filters (over the same length of time) but the quality of the filtering is worth that little bit extra.

He was very helpful, patient, and responsive throughout the process. Overall, a very positive experience with both the product and the customer service. Highly recommended!

It doesn't work.
It doesn't purify the water. The tea and coffee I made were cloudy, so I decided to check the water quality and found that it didn't help at all.

Great filter 5*
Great filter 5* Easy to install and you can feel the water taste difference instantly. Quick tip for UK buyers- make sure you get the UB system that comes with flexible hoses and adaptors for 1/2 inch that is the most common in the UK, unless you want to drill a hole in your countertop for the provided faucet that comes in the package. No more jugs that needs cleaning and no more cartridges that needs replacing every 4 weeks. Customer service amazing and very responsive Overall very satisfied with the filter.

Ich habe vor kurzem den Waterdrop Untertisch-Wasserfilter für meine Küchenspüle installiert und muss sagen, dass er eine fantastische Ergänzung für meine Küche ist. Er liefert nicht nur sauberes und erfrischendes Trinkwasser, sondern hat auch die Qualität des Wassers zum Kochen und Geschirrspülen deutlich verbessert. Ich benutze ihn jetzt seit zwei Wochen und möchte meine Erfahrungen mit Ihnen teilen. Es trägt dazu bei, Mineralablagerungen auf Geschirr und Geräten zu reduzieren, so dass diese strahlend sauber und frei von Wasserflecken sind. Ich habe auch festgestellt, dass sich weniger Kalkablagerungen im Wasserkocher bilden. Außerdem schmeckt das gefilterte Wasser hervorragend und macht alles, vom Kochen bis zum Kaffeekochen, zu einem angenehmeren Erlebnis. Ich habe auch einen Unterschied in der allgemeinen Klarheit und Frische des Wassers festgestellt. Das vom Hersteller erwähnte siebenstufige Filtersystem entfernt effektiv Verunreinigungen und Schadstoffe und gibt mir die Gewissheit, dass wir sauberes und gesundes Wasser trinken. Die Installation war dank der klaren Anleitung und des mitgelieferten Zubehörsets überraschend einfach. Innerhalb kürzester Zeit hatte ich den Filter an meinen Küchenwasserhahn angeschlossen, und seitdem funktioniert er reibungslos. Er benötigt keinen Strom, was keine zusätzlichen Kosten bedeutet. Er funktioniert ausschließlich auf der Grundlage des Wasserdrucks. Mit einer Lebensdauer von drei Monaten entschädigt er für seinen Preis. Alles in allem könnte ich mit meiner Entscheidung, den Waterdrop Untertisch-Wasserfilter für meine Küchenspüle zu installieren, nicht zufriedener sein. Er hat die Qualität unseres Wassers verbessert und die täglichen Aufgaben in der Küche viel angenehmer gemacht. Ich empfehle ihn jedem, der sein Wasserfiltersystem zu Hause aufrüsten möchte.

Ho acquistato il sistema Waterdrop 15UB con filtro sotto lavello e rubinetto dedicato e devo dire che ha superato le mie aspettative. L’installazione è stata molto semplice e veloce, anche per chi non è particolarmente esperto, e tutti i materiali trasmettono una sensazione di qualità e solidità. L’acqua ha un sapore nettamente migliore: più leggera, senza odori strani e davvero piacevole da bere. Da quando lo utilizzo bevo molto più volentieri e ho finalmente eliminato le bottiglie di plastica, con un grande vantaggio sia economico che ambientale. Il rubinetto dedicato è elegante e discreto, si integra perfettamente in cucina e il sistema di filtraggio è efficiente senza ridurre troppo la pressione dell’acqua. Inoltre, sapere cosa sto bevendo mi dà una tranquillità in più. Prodotto ottimo, lo consiglio assolutamente a chi cerca un’alternativa pratica, sostenibile e di qualità all’acqua in bottiglia!
