Waterdrop UL12A Under Sink Water Filter, Upgraded for 10UA, Time Reminder | No Drill Required for Renters, Easy Installation, Reduces Chlorine, Bad Taste & Odor, NSF/ANSI 42 Certified (Filter: FUL12)

I am incredibly impressed with my Waterdrop water filter. Since installing it, the improvement in water quality is noticeable immediately—it removes that harsh tap water taste and leaves everything crisp, clean, and refreshing. The installation process was straightforward and hassle-free, which I truly appreciate. It feels sturdy, well-designed, and gives me great peace of mind knowing that my family is drinking filtered water that is free from impurities. If you are looking for a reliable, efficient, and high-quality filtration system that actually delivers on its promises, I highly recommend this one. It is a fantastic value for the quality of water it provides!

If you’re handy at all, installing the Waterdrop 10UA is a piece of cake. It installs inline between your cold water supply shut-off and the faucet cold water connection, and everything you need for a clean, tidy install is included in the box. Took me about half an hour start to finish. I’m on city water with a whole house softener, and even with that setup I noticed a clear improvement in taste after installing this on the kitchen sink cold water side. That tells you the filter is doing its job. I give the filter itself a solid 5 out of 5. The install gets a 4 — not because it’s difficult for someone with basic plumbing experience, but a true novice might need to take their time with it. Overall though, a quality product I’d recommend without hesitation.

Seems to be working fine , fast shipping, only been a couple of weeks, water does taste better, easy install

This product is by far the best and easiest improvement for my crappy tap water. I’ve been using and refilling 5-gallon water jugs at a dispenser station, and to my surprise, this water tastes better than bottled water! The old lady is happy too! The water pressure is the same as before! No leaks! The quality is the best water I’ve probably ever tasted. It got that nasty chlorine smell out instantly. Very quick installation. Straightforward. Will buy again!

Easy to hook up. Customer support is wonderful and 24/7. The app needs work. Make sure you download the app and do all the stuff they require before you hook it up. Otherwise they want you to scan a super small QR code or enter in a ton of numbers and they’re on the back, bottom. Not easy to get to once it’s under the dark sink and hooked up. The NFC/tap didn’t work with the app and my iPhone 16e. It just kept trying to give a link to the app that I already downloaded. I had to add the filter manually. All the app does it tell you your filter level. It has a widgets for keeping track of hydration. I was excited about this until I tried using it. It sucks. There’s no way to delete accidental entries. I’m not sure if I’m supposed to click on it every time I drink or it keeps track automatically. Probably because there’s zero directions about how to use the widgets. Otherwise this is a great filter. I live in an old building with nasty water and this is better than bottled water. The digital functions and app are kinda useless. I’m hoping the upgrade them. There’s great potential there. I would recommend this product because it’s easy to install and filters very well.

tl;dr; I purchased two of these to replace a competitor's units that have become difficult to find filters for. The Waterdrop 10UA Pro has produced better, to my taste at least, water and has a better design that works without getting water everywhere when changing the filters. I have had two under sink units from another manufacturer that I had to screw into the back of the cabinets under the sinks that I attached them to. At the time, this was the only way to put a good under sink unit in. After years of use, the filters for my original units has become difficult to find and the cost has gone up as well. This led me to shop around and see if there was anything else that was at least the same quality or better. Enter Waterdrop. I have a gravity fed filter from Waterdrop that I have not used yet, and I forgot that it was even from Waterdrop until after I found the 10UA Pro unit. Looking at the unit, it surprised me that more companies are not offering either an upside down mounted filter system or one like the 10UA Pro that sits on the bottom of the cabinet. No screws. Just attach the lines, twist in the filter and open the valves. Instant filtered water with perhaps the easiest installation method out there. It is quite impressive that the filter also has steel water lines instead of the inexpensive PTFE tubing that most under sink units come with. This makes the Waterdrop my new goto for places that I want a quick setup and easy to maintain filter at. I am looking forward to being able to place a towel under the 10UA Pro and remove the filter to see just how much water is actually lost. With my previous filters, there was always a lot of water that was everywhere on the towel that it was frustrating to have to remove everything under a sink prior to chaning the filter. While I have yet to do that, it looks like the Waterdrop 10UA Pro will have little loss which helps me get filters swapped faster.

Pretty much plug & play. Easy to install and connect. I can taste the difference in the water. I like that it is tucked away under the sink (no big contraption mounted on the end of the faucet) and that the filters will last about a year. This model has a blinky light on top that is supposed to come on when it's time for a filter change. I did, however, put a piece of painter's tape on the side of the filter with the install date just in case. I did not notice any measurable drop in water pressure. I also like that the filter simply twists off and on with like a quarter of a turn or so and snaps securely into place.

The water filter works perfectly and was easy to install. One of the hoses included in my kit may not have been crimped properly at the fitting. I called the customer service number. The response was immediate. I was sent a replacement part, and the filter worked perfectly. Customer service and follow-up were first-class. Becky handled the issue and stayed in contact via email throughout the resolution. Overall, the experience ordering from Waterdrop was excellent.

For years, I was stuck in the expensive and wasteful cycle of buying bottled water. I was easily spending £7 a week on plastic bottles, which I knew was bad for the environment and, as I've now realised, a massive drain on my finances. That's over £360 a year! I finally decided to look for a better solution and stumbled upon the Waterdrop 10UA Under Sink Filter. To say I'm impressed would be an understatement. Installation was surprisingly straightforward. I'm no DIY expert, but the instructions were clear, and I had it fitted under my kitchen sink in less than half an hour. The immediate difference in the taste of my tap water was astounding. That faint chlorine taste and odour that you just get used to? Completely gone. The water is now crisp, clean, and genuinely refreshing to drink. It’s honestly better than the bottled water I was buying. But it’s the peace of mind that truly makes this filter worth every penny. Knowing it’s NSF/ANSI 42 certified and significantly reduces a whole host of nasties like lead, PFAS, PFOA/PFOS, and chlorine is incredibly reassuring. In an age where we're becoming more aware of water contaminants, having this level of filtration directly from my tap gives me total confidence in the water my family and I are drinking. The high capacity of 30,000 litres is another huge plus. It means I don't have to worry about constantly changing filters. It’s a simple, one-time installation for long-lasting, pure water. Switching to the Waterdrop 10UA has been one of the best decisions I've made for my home. I'm saving hundreds of pounds a year, drastically cutting down on my plastic waste, and enjoying delicious, safe water every single day. If you're still buying bottled water, I honestly can't recommend this system enough. It pays for itself in no time and delivers on every single promise. An easy five stars from me!
