Waterdrop RF15-UF 0.01 μm Water Filter Replacement for Waterdrop 15UA/15UA-UF/15UB/15UB-UF/15UC/15UC-UF Under Sink Water Filter, Reduces Lead, Chlorine, Bad Taste & Odor, 2 Years

I've been using the Waterdrop Ultra Fine filters for about 2-3 years, so after having a one-time issue with a replacement cartridge valve, I turned to their support team where Becky reminded me what amazing customer service is in this day and age! Not only did she help me to quickly validate my previous orders, and thank me for my preemptive self-troubleshooting, she quickly both refunded me for a replacement I had purchased preemptively AND sent me an extra filter for good measure! I am extremely satisfied with the build quality, quick setup and replacement, fresh taste of filtered water, strong pressure flow, and their reliable warranty service and proactively support – will be sure to get more of my friends using Waterdrop products.

Great water filter the replacement was easy to install works perfectly & was reasonably priced. Shipped fast too I had it the next day

Have used my original Waterdrop filter for about 2 years before finally having to order a replacement. Had some issues with this order, but Waterdrop customer service (Becky!) was awesome and quickly resolved the issue for me. The new filter works great and have had no issues so far. A great addition to the kitchen that's a quick and easy way to get filtered water.

I have used this Waterdrop filter for a couple of years. The filter was easy to install and produces tasty water with no chemical or other tastes. More importantly, Waterdrop has very good customer service. I had an issue with one replacement filter and Waterdrop immediately sent us a new filter. Karina in Customer Service was excellent in following up and making sure I was happy with the product and the service. Will buy it again.

My city water sometimes smells like the sink is full of bleach. It also has a lot of rust sediment. My house is more than 70 years old. I expect there are iron pipes in the original plumbing, although my kitchen has been remodeled with whatever pipe material is in use now. A whole house filter isn't feasible, but I like to drink water, coffee, and tea; make pasta, soup, stews, etc. I've used various faucet filters, none of which were easy to install and remove, and lasted less than 3 months . I ended up back to the beginning with Brita pitchers. Not terribly convenient, as it takes extra time to refill them, and the filters need replacing every 2-3 months. A few years ago, I replaced my outdated kitchen faucet with one that has one handle and a pull-out spray, which 1) a faucet filter won't work; but 2 )left me an unused hole in the granite countertop. I added a bar faucet to the cold water line and this Waterdrop filter. (Actually, I hired a plumber.) The RF-15 has a recommended life of 2 years, or 16,500 gallons. I replaced it after 3 years. The water was still clear, didn't grow any mold sitting out in the dog's dish; neither of us got sick drinking it even though I used it 50% longer timewise than advised. But I am the only human living in my house. I pay the water bills. It would take me 20 years to use 16K gallons of water for everything - laundering clothes, and bed linens, showering, mopping, cleaning bathrooms, window cleaning inside and out, toilet flushing (including occasional houseguests guests and dinner guests for a week or two) some pressure washing, and outdoor plant watering. Occasional car washing. My monthly billed water cost is always the minimum,1CCF (748 gallons or less). This filter is only used on one cold water faucet in the kitchen - drinking and cooking, but not dishwashing. My way of excusing the fact that I used it for 3 years instead of the recommended 2. I'm not sick and the original filter was still giving me clean, odorless water. The price has dropped by 50% since I purchased the first one. So why did I take off a star? Because the case is made of heavy plastic. I don't know what the filter is made of, but the company advised me that none of it is recyclable. It goes into the landfill unless I can find some use for it. It's not completely sustainable, but I NEVER buy bottled water, and avoid food containers that are not glass if disposable. Plastic contributes more fossil fuel emissions than anything except diesel and gas-powered engines that are used to create, transport, fill, and transport again. After a heavy rain, I can see islands of them floating down the creek near my house. They are in the stomachs of all of us who eat animals and fish. If you use a string trimmer in your yard, the string is chopped into millions of invisible bits everywhere, ingested by deer, birds and other wildlife. I'll stop ranting now! Thank you for reading. Back to business: This undersink filter works great, is incredibly simple to install and remove, costs almost nothing per gallon for clean water, and makes much less 1000-year waste than other methods of getting clear, good-tasting and smell-less water for drinking and cooking.

I purchased the Waterdrop filtration system, and at first, it performed exceptionally well. However, after some time, it began making unusual noises and the water flow stopped altogether. Suspecting a faulty filter, I replaced it—but unfortunately, the same issue reappeared shortly thereafter. I then reached out to customer service, and this is truly where Waterdrop impressed me most. I was connected with Becky, who communicated attentively to my concerns. Without hesitation, she offered to send me a replacement filtration system. After installing the new unit, everything worked flawlessly. But the experience didn’t end there—Becky went above and beyond by also sending me a complimentary water pitcher as a thoughtful gesture. I am genuinely grateful for such outstanding customer service. It’s rare to encounter this level of care and responsiveness, and it has earned my full confidence. I wholeheartedly recommend Waterdrop’s filtration systems to anyone. Thank you, Waterdrop—and a special thank you to Becky! Becky truly deserves to be a Super Customer Service Representative!!

Easy to Install. Great bang for the buck. No leaks. No noise. Filtration speed is fast. If you have the water pressure too high it will cause kickback in the filter and cause the flow to be slow so you have to find the balance. I've used this system for almost two years now. Second filter started producing white flakes after a few months, possibly because of too much pressure kick back. Costumer service is great though. Karina helped us get a replacement easily. Thanks Karina! You Rock!

I know they are pricey but my last one went 2 1/2 years. Not bad in considering the amount of purified water you get I like the brand and the filter took less than a minute to replace. Now it’s good for another few years.

L eau du réseau étant trop javellisée waterdrop est une excellente alternative pour avoir de l’eau sans sans goût de chlore
