Review: 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.
Review: 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.

### ⭐⭐⭐⭐⭐ Great Customer Service enhances the Great Product!
*by I***R on May 13, 2026*

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!!
