Waterdrop RF15 Replacement Filter Cartridge For 15UA 15UB 15UC Under Sink Water Filter Reduces PFOA PFOS PFAS Lead

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. Read more

The filter lasts a good amount of time, and I love that it’s affordable while still providing excellent filtration. It’s made a noticeable difference in the taste of my water, and I can tell the quality is much better compared to unfiltered tap water. Overall, I highly recommend the Waterdrop RF15. It’s simple to use, reliable, and provides great value for money. It’s a must-have for anyone who wants clean, great-tasting water without the hassle. Read more

I've been using the Waterdrop under-sink system for a while now, and replacing the filter used to be the chore I dreaded, but the RF15 cartridge completely changed that. Honestly, the twist-and-lock design is a lifesaver; I can swap out the old one and click the new one into place in literally seconds—no tools, no mess, no dealing with complex plumbing under the sink. The most important part, of course, is the water quality, and I can immediately tell the difference; the tap water chlorine taste is completely gone, leaving behind water that tastes clean and crisp, which makes me feel a lot better about drinking it and using it for cooking.

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. Read more

I have been using Waterdrop under sink filter systems for several years now. I even installed one in my mother’s apartment. The systems are easy to install and all necessary parts were provided. While I had two minor issues over time, Waterdrop customer support (Karina was the best) were quick and efficient in resolving my issues and quickly sent out any replacement parts needed. Karina provided excellent communication and follow up to ensure my complete satisfaction and issue resolution. I will continue to use Waterdrop products. Read more
