Waterdrop 10UB-B Under Sink Water Filter System with Dedicated Black Faucet

Excellent filtration and remove most impurities for health benefits and taste. I hooked this one under my bathroom sink. It's the perfect size, and the installation was easy for me—nothing extra to purchase.

Update (June 2025) It has been eight months, and the water flow has decreased considerably from 100% to 25%, despite its advertised two-year filtration capacity. Water flow is a significant factor. While it may be affected by Oklahoma City's water quality, I still find it worthwhile because it provides fresh water for drinking, cooking, washing dishes, and hands. Therefore, paying $5–$10 per month, depending on the filter's lifespan, remains a reasonable cost. Old review (Feb 2025) First of all I want to share that I live in Oklahoma city urban area to give a more specific views on the quality of water here. It has been 4 months since I installed the Waterdrop under sink water filter to improve the taste and quality of my tap water. Here's my experience with the installation, performance, and overall value of this system. Water Taste and Clarity: The filtered water tastes significantly better than my tap water, no smells. It's clear and the chlorine taste/odor/sediment has been greatly eliminated. Flow Rate: The water flow rate is good (reasonably slower than before installation) Filter Lifespan: I've been using the filter for 4 months and it's still performing well with no reduced flow rate compared to 4 months ago.

We were looking for ways to cut cost and after realizing we were spending upwards of 400$ for bottled water in a year, this was a no brainer. I didn't want to lose my "pretty" faucet to an ugly one with a brita filter, and I know I'd be the only one to keep an in the fridge pitcher full so we needed something more than just a filter. Our sink had a built in soap dispenser that hasn't worked for years so this was the perfect solution--filtered water and a faucet dedicated to it! It took about an hour to install but that was mostly spent trying to fit my shoulders through the cabinet to get under the sink and trying to blindly screw the nut into place that locks the faucet in place. The plastic disc that cushions the bottom of the sink from the nut is satan's work--it has a opening wide enough to sit around the threads that secure the faucet to the sink but I REALLY wish it had been a closed circle that could've just been slid on over the needed area. That made up probably 10 minutes of our struggle because you had to hold it on and screw the nut on with the same hand because there wasn't enough space to reach into the gap. Marking and mounting the filter was cake and I appreciate that it allows mounting vertically AND horizontally because to me, that means if it's just a smidge crooked, it's not the end of the world (spoiler: it's a smidge crooked). The faucet is great because the spout can be turned each direction. We have a very heavy dog bowl we used to have to balance while filling and now that we can just pivot that, we can sit the bowl on the counter to fill. Very handy. As of July 2026, the filter replacement is only 25.99 which is not bad at all for a year or 11k gallons. This did not come with teflon tape but it did come with the additional fitting you might need if you have a particular pipe fitting which I think is WAY better. We didn't need that fitting but I'd rather have and not need than go to Lowes and hope to god I get the right thing. Everything fit great, no issues. I wish the hose had size options because it's not something you can cut and refit and it was just way too long for our needs and it's a very rigid material so it's not easy to manipulate. No issues with leaking of any kind thus far. If there were I'm sure it would've been user error. As for odor I haven't noticed any kind of smell before or after installation. Can't reliably speak to the durability yet but I love this thing so much!! Just set a reminder to order a filter or setup auto ship!

The water drop 10 UB under the sink filtering system was wonderful it went in so easily the instructions were clear and it works perfectly .

Easy install, will need minimum 7/8in hole saw drill bit I personally used a 1in bit. This will give you room for error (the stem of the faucet is only half and inch using bigger bit allows you to adjust the facets placement in the hole while tightening, don’t recommend going over 1in hole saw bit size) I have it configured to not only run to the included faucet but the fridge water line also taps into the same line. I recommend buying cheap fridge waterline with this purchase. Aside from that I mistakenly bought this model and not the ultra filtration model, but upon testing water and comparing it to the unfiltered water the smell and taste is greatly improved. Taste very clean and no smell. If you turn on the faucet and you see it’s white, you have to use the included valve to reduce the pressure set once and forget it

The filter is very easy to install, as mentioned it removes odor and taste from the water. The water taste is good. But after using for few months, while I am testing the water noticed that chlorine was not filtered. Then I reached to Waterdrop customer service, the rep Karina had understood my issues and arranged a replacement filter. I appreciate waterdrop customer service, what ever questions related to their product we can reach them. They are very helpful, taking all measures to resolve the questions or concerns.

I genuinely don't typically leave reviews, but this was a big move for me, and I'm really glad I chose this one! Despite my just general confusion about installing new products, this product was extremely easy to install and the instructions provided were quite helpful. I do have some very basic plumbing knowledge, but even someone without it could absolutely install this! I really appreciated the fact that they included an adapter for the line that connects to the wall supply, because that would've been a hassle trying to find myself at the hardware store. The water tastes great and definitely is better than straight from the tap here. Worth the buy absolutely!

Just received a day ago, installed and currently using. So far we are impressed by the flow rate and taste of our water. No leaks everything installed without a problem and all hardware was included. If anything changes i will add to review later.

Buen filtro calidad precio y muy facil de montar

Installation très facile, contrairement à ce qu'on pourrait penser sur la photo, les flexibles inox sont de bonne longueur (70cm, ils sont enroulés avec deux tours sur la photo...), ce qui facilite grandement le positionnement du filtre. Il n'est par ailleurs pas obligatoire de le fixer, il peut être simplement posé verticalement et calé sous l'évier. Le filtre se clipse sans aucune difficulté avec un système quart de tour, il n'y a aucune fuite. On peut aussi installer un autre type filtre de la marque Waterdrop, c'est un système standard chez eux. Très efficace sur le chlore, le goût a disparu complètement. N'a aucun impact sur le pH et le TDS (c'est bien indiqué dans le descriptif, ce n'est pas le but, voir du côté de leur fontaine à eau à osmose inverse WD-K19-H pour ça). Concernant le débit, je remplis le réservoir de 5L de ma fontaine WD-K19-H en 45 secondes, c'est plus que suffisant pour un usage courant. Globalement, je suis très satisfait de ce produit, qui coche toutes les cases, il est de très bonne qualité au niveau des matériaux, s'installe vraiment très simplement (tout est fourni), et fonctionne exactement comme prévu.

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.

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!

Great water filter. I had previously bought a Culligan faucet filter and after swapping their expensive filter every two months for a year and always having quality issues I decided to try a more expensive (initial cost) under sink filter/faucet combo. This Waterdrop filter kit is amazing. It comes with everything needed and is easy to install if you're not a complete bone head. The water itself has no flavour, that's the point. Just good, clean water unlike my previous filter which always seemed to taste like chlorine. When looking for a replacement for the Culligan I was a little apprehensive on spending so much money. But if you do the math you will figure out that for the cost of this kit you would buy 4 Culligan filters which would only last a total of 8 months. This waterdrop filter lasts 24 months. So ultimately you will save money in the long run. Basically after 8 months it's paying for itself.
