I only write reviews when a product or service is exceptional or way below par. This review of the Waterdrop under the sink water filter with its own faucet, is of the exceptional kind. The filter and faucet are excellent. No more chlorine/chemical smell and taste. Faucet works perfect. It all goes together well with easy connections. Working under the sink is not a good position for me and I made a mistake and ruined one of the parts. After two emails to their customer service department, I was sent what I needed and I'm a happy camper again. A special thanks to Karina for her understanding and prompt solution. I highly recommend their product and thanks as well to their customer service department, Waterdrop gets a big thumbs up. (Honest review. No incentive given)

    This is the second filter/faucet I’ve purchased from this company. The components are high grade, and the installation instructions are easy to follow. It comes with all the adapters you will need for a basic DIY hookup.

    I had a special case where my plumbing was too close my sink basin for the included water supply fitting to be attached. The company provided Excellent customer service in helping me source an additional hose that let me complete the install, and even provided me a refund for the cost of the additional part.

    I should also mention that my water tastes MUCH better with the filter installed.

    Clear instructions, good support online and by phone make this unit easy to install. Also, the faucet that comes with the filter looks classy on our granite countertop. Rate of flow through the filter is plenty and the water tastes fine. I only installed this filter two weeks ago so I'm eager to see how it will perform over time, but so far so good.

    Works really well.

    Easy to install - basic DIY plumbing that's it. All the connections included - didn't need to purchase any adapters + the filter feels solid. The included faucet is really nice too... fits in perfectly with our main faucet. Great quality. Great kit - even included plumbers tape and drilling template to precisely mount the filter if need be. All well thought out.

    Filter works really well. We've been up and running for couple of months now and we are really happy with it. Huge step up from Brita in the fridge. We got the 15ub 0.5 μm which lasts for 2 years; the same filter but 10ub, you change every year.

    And a mention re the Waterdrop customer service. Had a few questions and they were fantastic. Their customer service rep Harper was really helpful, polite, quick to respond.

    So great product - great customer service - absolutely recommend

    This has been such a great purchase. I DESPISE tap water. Despite having very good and clean tap water I just can’t stomach the taste. This was easy to install despite zero plumbing experience and has been my faithful source of water since.

    The Waterdrop 15UB Under Sink Water Filter System is a fantastic addition to any home. It delivers clean, great-tasting water while removing impurities effectively. Installation is straightforward, with clear instructions, and the compact design fits neatly under the sink.

    This 15 UN under sink filter is amazing. To be able to get such clear, clean, and refreshing water is something everyone appreciates. Some filters deliver water at very low pressure but not this one. The pressure is excellent and your glass is filled to the top before you know it (in a few seconds). No odors or strange tastes, just crystal clear water. The installation was very intuitive. The quality of this system at the price point that it is offered is phenomenal. When it comes to customer service they are on top of it. In my communication with Olivia, two things were readily apparent. One, she cared about me as a customer and second, she made it clear that she understood my issue and moved quickly to resolve it. Throughout, it was obvious that Olivia represented her company well. Waterdrop is a top notch company from their quality products to their attention to customer service. I highly recommend this company and their products.

    5.0 out of 5 stars Makes the water so much better
    Reviewed in the United Kingdom on June 27, 2024
    Verified Purchase
    Got this to replace a small generic version which used the tube shaped filters similar to those in a fridge water dispenser. The small ones only lasted a short time and seemed to be of variable quality so I replaced with this one. Easy to fit (I did need my box of parts to get the right connectors though) only took a short time to do. I cut in a shut off valve at the same time and had to cut out a section of pipe where the quick fit connector of the old system was as it used the pipe puncture type connection (not sure what the real name is!) so I took that off and replaced the section that had the hole.
    Water quality seems very good, flow is much faster that the old one, taste is improved as we live in a hard water area and the water can sometimes taste "dry" due to the chalk. the filter looks easy to replace, just a twist off, twist on and says it should last for 15 months which, although more expensive, is good compared to the 3 months of the others. the cost of replacement looks to be slightly more than 5 of the other filters (over the same length of time) but the quality of the filtering is worth that little bit extra.

Product description

Please note that this Undersink Water Filtration System cannot reduce TDS.

If you need to reduce TDS, the Waterdrop RO System will be an excellent choice. For details, please search ASIN: B07P1XFYJP.

TDS stands for total dissolved solids. It is composed of inorganic salts and a small amount of organic matter. This undersink water filter cannot lower the TDS value because it removes harmful substances while retaining minerals such as potassium, calcium, sodium, and magnesium, which are beneficial for your health.

For separate faucet you already have

WD-15UC system ( Search ASIN: B085G9T9TB ) would be a better choice if you want to install it to the separate faucet you already have. It comes with the 1/4" PE hoses. If your faucet hose size is 3/8", you need to buy the 1/4"–3/8" converter fitting to help you connect the system. But if the hose size is 1/4", then you can connect with the system directly.
