Highly recommend
I have had this faucet and filter for a while now and am highly satisfied with it. I bought this so I could stop using water bottles. The installation was pretty easy, I did not have any problems. I have not been having any leakage or odor or anything bad. After doing the initial flush of the faucet, the water has been crystal clear with a great taste ever since. The small faucet looks good next to the main one, making it a practical and space-saving place to have my filtered water. I use the water to cook instead of taking out 5 water bottles. This has been one of the best purchases I have made for my kitchen. I like how easy it is to buy and replace the filter when its time is up.

Waterdrop 10UB: Fresh Filtered Water in Under 30 Minutes
The package came with everything I needed for installation, and the instructions were clear and easy to follow. From opening the box to having fresh filtered water, the whole process took less than 30 minutes. I've been very happy with the performance so far. The system operates silently, with no noticeable noise at all. It also does a great job removing the chlorine odor that is sometimes present in city water, which has made the water much more pleasant to drink. Water flow and pressure are both excellent—I haven't noticed any reduction compared to the unfiltered line. Overall, I'm impressed with the water quality and convenience. In fact, I plan on getting another one for the upstairs bathroom so I can have fresh filtered water readily available without having to head downstairs to the kitchen every time I want a glass in the evening.

Dramatic taste improvement and surprisingly easy to install!
I live in an area where the tap water has a strong chlorine "pool" smell and lingering concerns about PFAS. After getting tired of refilling a pitcher four times a day, I upgraded to the Waterdrop 10UB. For the price, the peace of mind and convenience are unbeatable. The Breakdown: Filtration Performance: The difference in taste is night and day. It effectively removes that chemical chlorine aftertaste and is tested against NSF/ANSI 42 (for taste/odor) and NSF/ANSI 53 (specifically for lead and PFAS). Unlike many basic filters, this one actually targets "forever chemicals" (PFOA/PFOS), which was the main selling point for me. +1 The "11K Gallon" Capacity: This is the workhorse of under-sink filters. Most filters at this price point give you maybe 2,000 gallons. At 11,000 gallons (roughly 12 months of use), you can use this for drinking, cooking, and filling the dog's bowl without constantly worrying about "wasting" the filter life. Installation: I am far from a plumber, but I had this up and running in about 15 minutes. It uses push-to-connect fittings that are basically foolproof. The kit includes a dedicated brushed nickel faucet, which feels much higher quality than the plastic ones you usually see. Pros: No Waste Water: Unlike Reverse Osmosis systems, this doesn't waste a single drop of water and doesn't require a bulky storage tank taking up your whole cabinet. Fast Flow: Even though it’s filtering out lead and PFAS, the flow rate is solid. It fills a 12oz glass in a few seconds—no more standing around waiting for a slow drip. Space-Saving: The filter is slim and vertical. I still have plenty of room for my cleaning supplies under the sink. Cons: Does NOT Lower TDS: A common misconception is that this will lower your TDS (Total Dissolved Solids) reading. It won't, because it leaves in healthy minerals like calcium and magnesium. If you want 0 TDS water, you need an RO system. Dedicated Faucet Required: This specific model (10UB) comes with its own faucet. If you want to connect the filter directly to your existing kitchen faucet, you should look at the 10UA model instead.

Works well. Way more convenient than pitchers.
This sure beats using a pitcher. The filter was easy to install with the included hardware. I did shorten the hose. The filter takes the chlorine and metal tastes out of the water. The faucet is well constructed of heavy metal material and has been working well. The valve is very positive and doesn’t leak.

Good customer service
UPDATE: The company reached out after seeing my low score review. They offered me a replacement product as a kind gesture. I wasn’t interested in the same product so they sent me a Waterdrop water pitcher w/filter. They sent it within 2 days and I will say it works very well, sturdy built and filters the water fast. Helps improve tap water taste a lot. I will buy a replacement filter when this one wears out. A+ for customer service and they did NOT ask me to write this or to change my review. I did it on my own. Changed to 4 stars based on my experience Original review- Cheap materials. I’d worry about it leaking. Especially while on vacation etc. I returned it and will stick with popular brand names

Solid Performance and Simple Setup
I purchased the Waterdrop 10UB Under Sink Water Filter and overall it’s been a good buy. The water taste is acceptable and I can notice an improvement. One thing I really like is the water pressure and flow rate — it delivers a strong, steady stream and doesn’t feel slow. Installation was also straightforward. Everything I needed was included in the package, so I didn’t have to buy any extra parts. On top of that, the color and material quality look great and match my current sink setup nicely. Overall, it’s a practical under-sink filter that’s easy to install and provides solid water flow.

El mejor en relación calidad-precio
En el apartamento tenía montado un sistema igual de otra marca y este año de repente el filtro de recambio ha pasado de costar 35€ a 100€. Una locura que no tiene explicación alguna, sobre todo si se tiene en cuenta que el recambio del sistema de ósmosis (3 filtros más postfiltro) que tengo en mi vivienda principal me cuesta 60€ con instalación (mucho más barato todavía si lo haces tú). En fin, que no me daba la gana pasar por el aro, así que me decidí por este sistema. Compré el sistema completo pensando que el filtro no sería compatible con el que tengo, pero qué va. Cabe perfectamente. Sustituí el anterior, pero aprovechando los tubos que ya tenía instalados y solo cambié la "carcasa", es decir, donde se inserta el filtro. Podría haberlo devuelto y quedarme solo con el recambio, pero al final pensé que quedaba mejor así. Por 100€ ahora tengo un sistema completamente nuevo (con tubos y grifo de recambio, ya que conservo la instalación anterior) y 2 (!) filtros de recambio. El sabor es igual de neutro que el anterior, así que todo perfecto. Para instalación de 0 vienen todos los componentes y es bastante sencillo montarlo, así que lo recomiendo sin dudar para todas las viviendas con poco espacio debajo del fregadero y, en especial, para apartamentos. Para tener agua buena los fines de semana y en vacaciones es insuperable.

easy to install
This is a solid product that gives me real peace of mind knowing I'm drinking filtered water. The filter is rated to last a full year, which makes it a fantastic value for the price. Installation was straightforward, though you’ll need a bit of DIY skill if you're drilling into quartz countertops. For wood or laminate, the instructions clearly specify using a 3/4-inch hole saw. Overall, a great buy!

Filter ok men inte mer, kranen är ren skit. Gick sönder efter fyra timmar.
Efter inkoppling satta jag i närheten av köket. Hörde då ett ylande visslande ljud. Visar sig att filterkranen började läcka inuti samt gick inte att stänga av. Tvingades att koppla ur den efter FYRA timmar!!! Ingen retur möjlighet då köpet & montaget var veckor för långt isär. Ännu en kina shop med dålig kvalitet.
