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

This is the best filter and system ever. The system is super easy to install yourself, it is very affordable, and delivers amazing results. I live in an area with highly clorinated water, so much that when you flush or turn the water on, it smells like someone has a bottle of Clorox. Also very hard water with a ton of nasty minerals I don't want. This takes every bit of chlorine smell and taste out of the water and creates a perfect drinking and cooking water.

Becky in customer service was fantastic. We haven’t been using the Waterdrop system for years without any problems. However, when the latest replacement filter arrived, installation resulted in the water flow stopping completely. After explaining the problem to Becky at Waterdrop, I was shipped a complete new unit + extra filter. I love the under the sink model. Incredibly easy to install and the water quality is excellent. I never used to drink tap water but now it is delicious.

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!!

This is a quality filter and changing it makes it the one!

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.

Love these so far. Easy on and off. Effective. Long lasting.

Works very well. I highly recommend. Takes out Iron in the well water, no aftertaste. Removes what it says it does. It also lasts for 2 or more months, depending on each situation you might have with your water. I have been using this cartridge under my kitchen sink only on the cold side for years now. Love it. I had to add a few valves and some PEX work. I live in a RV. One might want a pro install it, so you can isolate the filter for easy changing of the cartridge. Good water pressure until it has done it's job. Great value.

We put this under the sink in our travel trailer. It goes on the cold side. It was easy to install and I hate plumbing. The water tastes better. Our coffee definitely tastes better in the morning. Remember to take it out when you winterize your trailer or else you get to buy a new one. LOL
