Works perfectly, affordable, and easy to install
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.

Great product. Great customer service.
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.

Does the job as described. Very good filter!
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.

Great filtration, simple to install, & replace
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 A few years ago, I replaced my outdated kitchen faucet with one that has one handle and a pull-out spray, which 1) a faucet filter won't work; but 2 )left me an unused hole in the granite countertop.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.

Clean and fresh
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

Easy to Install and Works Great
I like that it was easy to install and that it lasts for a long time. Just had to twist it in and turn on the water and we were ready to go. Helps save a lot on buying bottled water. The water is clear and filtered well.

2 perfect units
The unit itself was so easy to install. Two screws in the wall, a couple quick water lines and badaboom you got filtered water. I had an issue with the replacement filter however it was quickly resolved. The customer service was top notch. Frustrating at first, but Kimberly was so nice and really made the situation right. They immediately sent a new replacement filter that worked perfectly. Really have bought into the ecosystem and considering one of their higher end systems now. For the price on this you can’t beat it. Installed 2 units in my house.

Fantastic and reliable DIY filtration system
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.
