Excellent product. Filters out all taste of chlorine. Easy installation of system. Filter lasted over 1.5 years for a family of 5.

Great water filter for drinking and using for espresso machines. Design is easy to install for functional under counter use.

Advertised as usable for 2 years - which is completely wrong! After 2 month of installing, water only drips out, no more pressure at all, completely clogged - for that price useless. That's on normal municipal water source. Maybe that's where the name "waterDROP" comes from.... Will look for different brand now.Edit: Through Amazon it was impossible to get in contact with Waterdrop customer service since it was "shipped from Amazon" and Amazon didn't try to find a solution to have a working filter system as advertised. However, somehow Waterdrop got in contact with me (due to the initial review?) and it was a great experience from that on! They cared about what happened, and made it right; sending new filters and cared about even after sending it out if the new one worked or not. They still stay in contact to see if there is a problem again or all works still - really great customer service, service one doesn't see often anymore these days unfortunately. Will I buy a new filter from Amazon again? Probably not. Will I buy a new one from Waterdrop directly in the future when needed - 100% yes. Updated rating to 5 stars due to their great customer service. All good with the new filter, no water pressure issues anymore.

Easy to replace; although I'm not handy, I was able to do this myself. However, tip for newbies: even when you're following the instructions and have turned off the water supply and drained the faucet, it will still leak when you remove the old filter. So have a large pot/bowl ready to catch the water underneath. The filtered water tastes good. We used our first filter for 18 months, but a couple of our family members drink a LOT of water, so I think in the future we'll replace at least every 12 months. Even replacing every 12 months, the price is WAY better than most other systems out there, so I'm happy.

I purchased the RF15-UF filter on Amazon in February 2023 to replace my old RF10-UF filter. I switched to the new filter at the beginning of June 2024. After using it for less than a month, I noticed a weaker water stream. Living in a large metropolitan apartment and using city water, I was unsure why it lasted such a short time.I reached out to the customer service department to address the issue. They promptly provided me with a new filter and an additional filtration system to extend the filtration capacity. Their proactive approach and commitment to quality truly impressed me.I am extremely pleased with my experience and the exceptional customer service I received. They stood by their product and ensured I had the best possible solution. I highly recommend this product to anyone looking for reliable water filtration with outstanding support.

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.

The water filter works great and was incredibly easy to install. However, I ran into an issue where, after about three months of use, the filter started making a loud hammering or vibrating noise. I thought it might just be a defective unit, so I bought a replacement, but the same thing happened again after about three months.Eventually, I did some research and discovered that high water pressure could be the cause. To fix it, I went under my sink and slightly turned down the water pressure on the cold side—not much adjustment was needed. Since then, the noise has stopped, and the filter has been working perfectly.If you’re experiencing the same issue, this might be worth trying. Overall, I’m happy with the product now that I’ve resolved the problem!

I wanted the 3 filter set up but due to space I had to opt for the system that uses this big filter. Very happy with it. This was a filter replacement and the switch was very easy and with little water coming out. I highly recommend WaterDrop UF system as this filter is quite excellent.

I have 2 of these inline systems in my home, one in my bathroom connected to my faucet and an inline water flosser on the faucet tap and the other is in the cabinet next to the refrigerator. I don't really "need' this on my bathroom, but it is there and it makes flushing my refrigerator filter MUCH easier. Instead of getting 30 or 40 glasses of water (3G) from the fridge to flush a new filter, I put the new filter in my bathroom and ran the faucet for 10 minutes. Then I put my newly flushed filter into the cabinet for the refrigerator water/ice.I recently purchased a new refrigerator, and the filter made the water taste disgusting. I am so grateful that they made a bypass filter, so I immediately purchased that, and I am back to having good tasting ice and water at the fridge. This is a 2-year filter, but I may let it go for even 3 years as I have a whole house sediment and charcoal filter in the garage before it even hits these filters. We don't use all that much ice or drink that much water from the fridge.These filters are certainly better priced than the MFRS, they last longer and install is easy. If you are using these for the refrigerator instead of the MFR's filters, install a shut off valve just before your waterdrop to make changeout easier so you don't have to move the appliance to shut the water off. You would want to get the one with the push to connect thin white tubing. Quick connect shut off valves for 1/4' tubing are sold here on Amazon for cheap. A little bit of water will come out no matter what during changeout, but you will only need a washcloth to wipe it up.
