What I Love About It: Effective Filtration: The multi-stage filtration process removes chlorine, lead, heavy metals, and other harmful contaminants, providing purified water with every use. I feel much more confident drinking tap water now, knowing it’s been thoroughly filtered. Long-Lasting Filters: The 3-year lifespan of the filter is impressive. It’s a hassle-free system that doesn’t require frequent replacements, saving both time and money in the long run. Quick and Easy Installation: Installing the filter was surprisingly simple. The system comes with clear instructions, and all the necessary components are included. It took less than 30 minutes to set up and start using.

Great-Tasting Water: The water tastes crisp and clean—there’s no aftertaste, and the quality is noticeably better than before we installed the filter. It’s perfect for drinking, cooking, and making coffee or tea. Convenient Water Flow: The water flow rate is fast and consistent, so there’s no delay when filling up glasses or pots. It’s like having a high-quality water filtration system in the comfort of home.

If you're looking for an efficient and low-maintenance water filtration system that delivers great results, this is the one to go for! Highly recommend it for anyone who wants purified water with minimal effort

Very easy to install ! A bit taller than we thought but it worked out ok ! It definitely cleans the drinking water for a better taste ! I’m even going to get more The only down side is replacement filters where to purchase they make it hard to find ! But definitely recommend this product

Been using this for a while now, very happy with the quality and the functionality. It’s taken out the chlorine taste of our water. We’re very happy with this purchase. Would recommend this one.

Installed fairly easy. The water flow through this filter is about the same as no filter.... so I am a little skeptical of how well it is actually filtering sub-micron particles. A filter should restrict water flow somewhat as it should be harder to force water through a tight filter membrane. I'll cut this open and look at what is actually inside when it's time to replace. Water tastes good though.

Moved into a new house just outside a city, not expecting that I was going to have unexpected brown water 2x a month without notice. I had always lived within the city that never had this problem so it never crossed my privledged mind that brown water was going to be issue. Water filter for the main water line in our house was going to be super costly so I came to the decision with my fiancé that we’d atleast get a water filter for the kitchen sink until we can afford one for the main water line. This filter was easy to install and fit perfectly under our sink as it’s slim and isn’t an eye sore. It was a little bigger than we expected but they tell you to measure before you buy it. I did notice that one day we had brown water but the kitchen sink water was running clear so it definitely works. It’s nice to not have to worry that we’d suddenly have brown water when it comes to cooking or even hosting people. I did notice that there is water scale still on some of our cutlery/cooking ware but I’m pretty sure the company states it doesn’t remove minerals in the water. With the price that I paid and that the filter only get replaced every 3 years, it is very affordable. Even if my filter needs to be replaced sooner due to harder water, it’s still affordable compared to other filters. Regarding water pressure, it remains the same for me. I’ve read reviews of people saying their water pressure has drastically decreased but I think they did something wrong. My water pressure is still powerful and even still sprays water everywhere, getting water droplets on everything around the sink - on the highest setting. I would definitely recommend this! Update 8/5/23 - Water pressure is still pretty strong considering it was previously powerful. I usually avoid running the water when it’s brown but I’ve ran the water through the filter a few times while it was discolored and it came out clear. I probably will end up changing it at the 3 year mark.

Installation was easy and the filter has removed the tap water taste from my water. So far I'm very impressed!

I bought and installed this unit a few months ago and am very happy with the quality of water it filters. I have very hard water in my area and a water filter is required if you don't want to taste the strong mineral flavor that comes from my tap. Installation was simple, quick, and straightforward with the steps being outlined detailed and the kit included a little sticker guide which made drilling accurately very easy. There is a clear reduction in water pressure when you turn on the cold water (the pipe that the filter should be installed on). However it isn't enough for it to be a big issue since you can fill up large containers of water in a fast amount of time compared to my previous water filter. The filter state they can last 19,000 gallons however I assume that is in ideal conditions and doesn't take into account areas with harder water. However with how cheap the replacement filters are, I can just go ahead and buy one every year and take the 5 seconds or so it takes to swap it out. I wish the filters would have some kind of indicator that shows its almost done but again I can't hate too much on it considering it's price. All in all it is a good value and well worth the price to get fresh drinking water in an easy to install fashion.

Decided to try a different brand after using the same style Woder brand inline filter for years because of the price point. Installs and works the same, took maybe 5min to install after clearing under the sink and putting the screws in place to hang the unit. Instant improvement in the flavor and smell of my crappy city tap water. Removes the swimming pool flavor and egg smell. Time will tell if it lasts as long as the Woder (3yrs). Really happy everything I needed other than the wrench came in the box; including thread tape and an adapter for 1/2" lines. Nothing is more annoying than working on plumbing and realizing you need thread tape.

Problème de plomb dans l'eau et odeur de chlore importante, tout est réglé. Nous utilisions un filtre de type Brita auparavant, vraiment rien de comparable avec ce filtre sous l'évier. Facile à installer (genre 5 minutes), la pression d'eau est excellente et l'eau qui en sort est cristalline, sans odeurs et sans plomb mais n'a pas perdu toute sa saveur, l'eau ne goûte pas l'eau stérile comme certaines eaux filtrées. Je vais en installer un au chalet également. C'est vraiment un super produit. Je recommande fortement.

Very impressed how easy it is to install and how well it works, much better than Brita filters

Very happy with this product. Easy to install. My partner took about 5mins to put it for me. It's tall but fit perfrctly, didn't take too much space and stylish. Water taste smoother and same flow, so very happy.

The first one a bought worked flawlessly for 3 months and then it would stop the cold water when I opened the faucet to full. I could only open the cold about 30% or it would rumble and shut off. I went through customer service where Carina and Tania helped me troubleshoot the problem and see if a solution could be found. Since the problem couldn't be resolved, they sent me a whole new unit and I'm pleased to say that it's working like a charm again! Water tastes great and without any further issues, we're looking to becoming long time customers. It's seriously easy to install and the filters are rated to last 3 years, saving you so much money over the Brita system we has before which is more costly as you have to buy filters every 3 months. We highly recommend this product and like I mentioned before, Waterdrop has great customer service with quick responses and excellent communication.

Purchased the 17UA in late October 2025. Have had different water filters in the past including Kangen water filters. Easy to install with all hoses provided which really makes it simple. Although we didnt test the water for the level of contaminants, the water is clear, odorless, and great. Fast forward to late February 2026 and the water had an odor yet was still clear. Contacted Waterdrop and communicated with Becky in customer service. She immediately addressed our concern and promptly sent us a replacement filter within 2 days. Now all is well and the water is again perfect. Highly recommended waterdrop not just for the quality but also the customer support. Becky is extremely thorough, kind, and helpful so you have no worries as she takes care of any issues you may have. Thanks Waterdrop
