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.

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.

Great price and improved water quality instantly
So we had a brittas filter jug and was getting old. Was not cost efficient at all and sometimes we could still taste the chemicals after filtering water when we boiled the water in the kettle with a new filter in the jug.! This was a game changer for us as in London water is not great a all in our areas. It’s been so cost effective and very consistent in water quality for both tea and as drinking water. Filter I think needs changing once a year or even longer depending on family size and water usage. I have told all my friends just get this as it does improve the water quality for sure. Fitting it was easy and cartridge below sink unit in cupboard is so thin it does not take up much space at all which was our main worry as tight cupboard and storage space. Lots less hassle than brittas jug and it’s expensive cartridges.

Excellent Water Filter with Great Taste and Easy Installation
The Waterdrop 15UB Under Sink Water Filter System is a fantastic addition to any home. It delivers clean, great-tasting water while removing impurities effectively. Installation is straightforward, with clear instructions, and the compact design fits neatly under the sink. The water flow is strong, and the filter life is impressive, reducing the need for frequent replacements. It's a cost-effective and eco-friendly solution for fresh water. Highly recommended!

Greatvwater filter
I've been using a filter jug for many years and decided to try a water filter integrated into the cold water system. The filter is quite large and wouldn't actually fit under my sink but my partner managed to locate it in an adjacent cupboard, there was plenty of hose to accommodate this. He said it was quite tricky to navigate around the existing pipes. We also had to situate the tap in the kitchen top rather than the stainless steel bowl as there wasn't any room to do that. Not it's in place it's great! water tastes very different and it's lovely to have nice tasting drinking water on tap!

So easy to fit
Already had a water filter from EWT, which costs £300 to replace the cartridge. So decided to completely replace it, which was a 30 minutes job. Water seems ok, no odour etc, so yes very good choice

Wow, was für ein Unterschied!!!
Ja der Unterschied ist unglaublich. Wir leben im Saarland/Hochwald mit genug frischem Wasser und Wasserhärte 1 und doch ist das gefilterte Wasser um Welten weicher als das ungefilterte. Der Unterschied ist sofort spür- und schmeckbar. Total weiches Gefühl im Mund. Der Kaffee schmeckt total mild ohne die Einstellungen am Kaffeeautomat zu ändern. Der Kaffee war mit diesem Wasser auf einmal zu mild, zu süß, zu viel Milch. Bis jetzt klare Kaufempfehlung. Über die Langzeitanwendung kann ich jetzt noch nichts sagen, werde ggf. nach berichten. Die Montage stellte sich bei weitem nicht so einfach dar wie angegeben, doch am Ende lag es einfach an der bereits vorhandenen Installation der Leitungen die mir das ganze erschwerte. Doch es funktionierte wenn man nur halbwegs handwerklich begabt ist.

Excellent product/Excellent company
I only write reviews when a product or service is exceptional or way below par. This review of the Waterdrop under the sink water filter with its own faucet, is of the exceptional kind. The filter and faucet are excellent. No more chlorine/chemical smell and taste. Faucet works perfect. It all goes together well with easy connections. Working under the sink is not a good position for me and I made a mistake and ruined one of the parts. After two emails to their customer service department, I was sent what I needed and I'm a happy camper again. A special thanks to Karina for her understanding and prompt solution. I highly recommend their product and thanks as well to their customer service department, Waterdrop gets a big thumbs up. (Honest review. No incentive given)

Perfetto
Funziona benissimo, è perfetto e il rubinetto molto bello. Il kit è completo di tutto ed è molto facile da montare. Rimane da sapere l'effettiva durata della cartuccia.

Acqua buona, praticità e zero plastica
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!
