This is great and easy to install! The water tastes so much better and I like that I can use filtered water when cooking pasta, making coffee and other things. Also like not having to fill a pitcher all the time 😆

Great Product, easy to assemble. The first one I ordered had a defective washer so I returned and ordered a second one. It took less than 5 minutes to fix it, no tools needed just hand tight. performs great. Great quality, water tastes nice.

This water filter was exactly what I was looking for! We had an under cabinet filter that worked fine but did not filter out taste. I did my research and settled on this one. It was very easy to install and I did it myself. Best of all, our water now tastes great! Highly recommend it!

I've been using the Waterdrop 15UA Under Sink Water Filter System for a few weeks now, and I'm overall quite pleased with it. The water tastes noticeably better, and I appreciate the reduction in chlorine and other contaminants. However, the one downside I've noticed is a significant decrease in water pressure. Pros: Excellent water quality: The filter effectively removes chlorine, sediment, and other impurities, resulting in cleaner, fresher-tasting water. Easy installation: The system is designed for DIY installation, and the included instructions make it straightforward to set up. Long filter life: Each filter cartridge lasts up to 24 months or 16,000 gallons, reducing the need for frequent replacements. Affordable price: Compared to some other under-sink filter systems, the Waterdrop 15UA is a budget-friendly option. Cons: Reduced water pressure: The most noticeable drawback is the decrease in water pressure. While it's still usable, it's definitely a trade-off for cleaner water. Overall: If you're looking for a reliable and affordable under-sink water filter that significantly improves water quality, the Waterdrop 15UA is a good choice. However, be aware that you may experience a decrease in water pressure. Additional Tips: If water pressure is a major concern, you might consider a different type of filter system, such as a reverse osmosis system. Regularly check the filter cartridge and replace it as needed to maintain optimal water flow and filtration. I hope this review is helpful!

Been using it for a year now and the water filter still works really well! It was easy enough to install and started working right away. I love that it gives me peace of mind knowing the water is safer to drink. For the price, it’s really a great deal and so much easier than having filtered water in a fridge. And no need for plastic water bottles!

Honestly, this is probably my best purchase on Amazon and trust me, as an Amazon Prime member I order from them constantly!! I am extremely pleased with this Waterdrop filter. It is very easy to install as it connects to your cold water line and voila, super clean and great tasting water from the tap! For years, I was a slave to lugging bottles of water home. I preferred purified water only and bought the 2.5 gallon containers with the tap. With all of the brands of water on supermarket shelves, you’d be surprised how little the selection is when it comes to “purified” vs. “spring” water. This meant I had to go to the local pharmacy because they always carried it. Purified water was essential for me because I received a bone marrow transplant some years ago and spent many weeks in the hospital for the procedure. I am a huge water drinker and the ONLY water offered in the hospital to BM recipients was purified water. Hence, I continued to drink only purified water because of its higher level of purity when compared to spring water. So, basically I’m a water snob lol. While selecting a filter, I was obviously concerned about the quality and taste, but also the possibility of a loss of pressure. I’m happy to report that the Waterdrop filter addressed my concerns and exceeded all my expectations!! I do not have my own well. Instead, my neighborhood has a community well that treats the water and we are all charged based on usage. Still, the taste was awful. Also, it contained a high level of lime scale which clogs up my sprayer heads so I have to use cleaning products to remove it. It is also has a noticeable chlorine odor and taste. With this filter, my water now tastes clean, “nonminerally” and its odor free. The cost savings is huge!! I can’t believe how much money I poured down the drain. Also, there was no loss of pressure. Keep in mind it hooks to your cold water supply. This is fine because who consumes 8 cups of hot water a day anyway? For cooking, I use cold water that gets heated up anyway. My coffee tastes much better. Also, it’s better for my pets! I highly recommend this water filter. It is a great value and saves you a considerable amount of money in the long run! It is more practical than water pitchers that require filter changes. I’ve had it installed for 3 months now with no issues. I’m pretty sure you will feel the same way.

I have absolutely loved having this in my kitchen sink. It does exactly what you expect from it, enjoy clean filtered water with ease. I love how easy it is to install by just connecting it to the cold water valve under the sink and the taste of the water is great as well. It is nice to know that the water I'm consuming at home is free of any contaminants and is safe to drink for my family. I did have an issue about 10 months into my purchase where I began to hear noises coming from under my sink and the cold water stopped flowing. I emailed customer service and they were so helpful. Robbie Li was the representative who assisted me and I could not ask for a nicer and professional interaction. Robbie was prompt to tell me that my problem was that the head was clogged and he immediately arranged for a new unit to be sent to my house. Afterwards, Robbie checked in to see if everything was okay and that the installation went well. I've honestly never had such a good experience with the customer service of a company like I had with Waterdrop. If you ever face a problem with your filter don't hesitate to contact their customer service they are phenomenal.
