Waterdrop 15UA Under Sink Water Filter System, 2 Years, Reduces Lead, Chlorine, Bad Taste & Odor, Under Counter Water Filter Direct Connect to Kitchen Faucet, NSF/ANSI 42 Certified, USA Tech

Makes tap water taste like expensive water bottles. AMAZING ! Installation is easy I had a harder time cleaning under the sink.( I have a spray bottle for EVERYTHING ) OMG. Filtration, yeah easy snap in o ring plugs make a positive connect and the 3/8 standard fitting in and out . I used 3/4 wood screws so it wouldn’t penetrate into the other cabinet for the holder . If you want hot water to be filtered as well you would need one of these kits for your hot side

Let me preface this by saying this is my second time buying this exact filter from this company. I bought one for my first apartment and it outlived my stay there. I moved into a new apartment and purchased it again without hesitation. Water taste? GONE. 100%. The strong chemical taste and smell are completely gone. I live in Fort Worth, Texas, where the municipal water is treated with chloramines and has a higher, alkaline pH (this is publicly reported in the city’s water quality data). If you’re sensitive to taste and smell like I am, you’ll immediately notice the difference. Design and installation: It’s long, slim, and takes up very little space, which is perfect for apartment living. I bought the quick-connect version and installation was quick and straightforward. It does require a few basic tools, but the process is simple and well explained. Important install tip: Keep filter replacement in mind when choosing the install location. You’ll need enough clearance underneath to remove it. Replacement is a twist-and-pull-down motion, so don’t install it too close to the cabinet floor. Planning ahead makes future filter changes easy. (Leave like 2-3 inches open) Practical and environmental bonus: I’ve stopped buying bottled water. A 40-pack at Walmart is around $6 and it goes fast. This filter cost me $129.99, and spread over about 5 years that’s roughly $26 per year, which is far cheaper than constantly buying bottled water. On top of the savings, it significantly reduces plastic waste, which matters to me. (Although I would never let it reach max capacity to be honest) Final thoughts: I genuinely love this filter. It’s effective, compact, easy to replace, and ideal if you live in an apartment and don’t have the option for a whole-house system. (Reverse osmosis still the best thing BUT I CANNOT AFFORD IT) Everyone should have one. My only wish is that I had the same filtration in my shower as well. Highly recommend.

I purchased this product based on reviews found online on consumer sites. This unit is intended for under the sink installation but i did not realize this when i ordered it. The unit comes with 1/2 inch and 3/8 inch supply lines which are pretty standard for the manufacturer intended use and installation. I feel no need to filter all tap water for washing dishes and such and wanted to use it for the water dispenser and ice maker built in to the fridge. My intention was to use it as a replacement for my GE refrigerator inside filter which as many others customers will testify is very expensive to replace due its relatively short lifespan (less than 3 months) even in a a two person household. A call to GE and they provided me with a bypass device to replace the onboard filter so i could install an exterior unit as many have done to great satisfaction. I contacted Waterdrop customer service and agent Karina was very helpful in trying to find me a suitable adaptor for the size difference of my refrigerator connections but we had both come up with the same problem. The needed parts were not available on Amazon so in conclusion we both agreed a visit to plumbing supply would be most appropriate. The parts i needed cost me $12. No problem, for me this was an easy fix and the filter works 1000x better than the onboard OEM unit that GE puts in their fridge. Even when new it would take like 20-30 seconds to fill a glass of water and now its like 5 seconds. Filling a pot of water to cook with went from maybe over 2 minutes to under a minute. Totally satisfied at this point i was surprised with a follow-up from Waterdrop and a short conversation led to an offer for a reimbursement of the cost for buying the extra parts i had purchased. In my opinion this is what i would call OUTSTANDING CUSTOMER SERVICE ! I will certainly update this review accordingly if the unit falls short of its advertised expectations.

Drinking water goes from an annoying hassle with water filter pitchers and dispensers which have to be moved around, cleaned, and refilled, lest they harbor mold and bacteria. If you have trouble staying hydrated because it is a hassle this unit is a great solution, especially if you are renting as you can't use normal under sink filters that require drilling holes. This filter is different, you just hook it up to your regular faucet. Even if this unit only lasted 6 months out of the year I would happily replace it because it makes drinking water that doesn't taste disgusting so much less of a hassle. (It of course doesn't reduce TDS but you don't really want that for most uses, unless you have special water filtration needs or have issues with water scale ruining your coffee makers, but RO purifiers actually have to add minerals back otherwise the water will taste funny.) The unit feels solid and had no problems with installation. It comes with adapters for most under sink hoses and teflon tape (although you likely won't need it since they have a rubber gasket for sealing). The filtering speed is fine, it doesn't noticeably reduce water flow (at least when new, will update if that changes), although the sink used has the smaller hose size. It's unlikely size will be an issue unless your under sink space is tiny.

It's what I needed

Worth the money for sure. No more plastic bottles. Even better tasting water

This is very very good and excellent product with zero water waste. It is also value for money. Looks exactly same as what it's shows. Ease to use and install. Product was installed on 29th Dec 2024 after delivered to to home. After installation first 3 days water quality was good and after that colour was bit changed as light yellow. But after few days water quality back to normal very pure and crystal clear. Below shown photo was taken on 24th May 2025 almost after six months. 💯💯💯💯 🆒✅✅✅Quality product.

I bought this Waterdrop filter and I’m honestly very happy with it. The installation was super easy and the design is clean and modern – it fits perfectly under my sink. At first, I thought the filter was broken because the water pressure was very low. I contacted their customer support, and Karina from the team responded quickly and was incredibly helpful. They even sent me a free replacement filter without hesitation! Later, when I reinstalled everything more carefully, I realized the problem was actually a kinked hose on my side – not the filter. I let them know about my mistake, but they still let me keep the replacement filter as a gift. That kind of customer service is rare these days. The filter itself works perfectly – the water tastes great, pressure is back to normal, and overall it’s a great value. I really appreciate both the quality of the product and the support behind it. Highly recommend!
