Waterdrop RF15-UF Water Filter Replacement for WD-15UA-UF/15UB-UF/15UC-UF

Easy to change out, plus great tasting water! The filter also allows great pressure at the tap, What more could you ask for!

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 was a replacement for the filter system we installed last year. Arrived quickly and easy to change the filter. I feel much better drinking our tap water and easier than using a canister filter. We installed this after the water dispenser in our refrigerator quit working. much cheaper than replacing the refrigerator.

Original filter review:The filters don't last. Water flow is cut by 65%. My last filter needed replacing after a month. Removing it for another brand. Updated review: June '26, I contacted Waterdrop about my filters not lasting. They determined it was probably the filter head that was clogged or defective so they sent a whole new head and filter. The new head has a much larger hose orifice that totally fixed my problem. What seemed like a clogged filter is working great now. All is well! Terrific filter system and Waterdrop is an equilly great company!

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'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.

We have this installed under our kitchen sink - it is so easy to replace - just takes seconds. The filtering is effective; I can’t taste the chlorine in our municipal water.

I’ve been using the Waterdrop RF15 filter and unfortunately my experience hasn’t matched the advertised lifespan. This filter is marketed to last up to 2 years or around 16,000–19,000 gallons depending on the model, but mine needed replacement after only about 10 months of normal household use. What’s especially disappointing is that I have the same under-sink filtration systems on other sinks in my home, all using comparable municipal water sources, and those filters consistently last over two years without any noticeable drop in flow or water quality. That makes this early failure stand out even more. Installation and water taste were both fine initially, and the filter performed well at first. However, the lifespan fell far short of expectations, especially given the manufacturer’s claims. It’s worth noting that actual filter life can vary based on water quality, but in my case the conditions are very similar across multiple systems, so this seems more like a product inconsistency than a water issue. Overall, decent performance while it lasts, but significantly shorter lifespan than expected compared to other filters Review Update: I wanted to provide an update to my original review. The company reached out and stood behind their product by promptly sending me a replacement filter. I appreciate their responsiveness and commitment to customer satisfaction. Their customer service definitely made a positive impression. Rating bumped up to five stars.

I have been using this system for approximately 3 and a half years and love it. The water tastes clean and usually last about a 1.5 years between filter replacement with regular use between 2 people. We each fill up our water bottles everyday before work which holds about 2 plastic water bottles worth of water to get an idea of volume. Easy to tell when it's coming to the end of it's life. Easy to replace and install yourself.
