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.

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.

LOVE THIS. My nephew took out the dish detergent dispenser from my sink, which I never used, and put this in the remaining hole. The dispenser arches up nice and high, making it easy to fill pitchers. The spout is very slim and sleek but able to dispense volume. The "handle" toggles very smoothly, the water comes out at a high flow when on high, even if the water is also running from my regular sink faucet. I love love love it. I can put filtered water now into my dog's bowl, and for me. The water tastes good and the filter doesn't have to be changed for a long time, I think it's 3 years, but we'll see. I have a tiny 2sink bowl in a 1930 house with limited space under the sink. My nephew secured it to the wooden cabinet wall and zip tied the tubing to the water pipe so I didn't have to give up one bit of under-sink storage space. Again, it's lovely.

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!

I replaced an old Culxxxx filter system with this Waterdrop - a huge improvement. The 3/8” supply line provides a tremendous flow, way better than the old 1/4” tubing the Culxxxx used. Well, the reviews saying install is so easy, not sure about that. The provided supply hardware requires a cut into the main cold water line. In my case there was an existing branch dedicated to the water filter spigot (since it’s a retrofit) so cutting into the main supply was overkill. The provided Waterdrop valve will not function as a stop valve, so instead I discarded it and used a 1/2” to 3/8” shxxk bite quarter turn stop valve installed on the dedicated filtered water supply line branch. It worked just fine (see picture). If you do this don’t forget to use 3/8 brass fitting insert into the 3/8 Waterdrop vinyl supply line so it can support the compression fitting from the shxxk bite stop valve. A couple other things, remember to install the blue locking clips on the filter input/output quick connects to keep the lines in place. The instructions forget to mention this but the clips are supplied. Lastly it appears the filter unit contains a battery that tracks filter life somehow. There is zero mention or explanation of this in the instructions but a sticky label is included which describes the function. So the instructions and install options could use a little tuning up for sure.

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!

Easy to install, after running the water for about 5 mins, we have crystal clear water that tastes pure. Works great so far paired with our Soda Stream. No more chlorine smell from city water! Great product imo.

Easy to install this water filter under the sink, easy Parts assembly. The filter works great so far and has greatly improved our water. The tap does have a high pressure but once you are used to that part, it is nice to have. Great value.
