## Questions & Answers

**Q: Does this system filters pfoa and pfas ?**
A: Dear Customer,
Thanks for your interest in our Waterdrop TSA 3-Stage Under Sink Water Filter.
This under sink water filter can more effectively reduce rust, sand, large particles, and suspended solids. The system can reduce part of PFOA and PFAS. But it is not designed for significant removal of pfoa and pfas.
Waterdrop reverse osmosis system will be a better solution if you need a system to lower the pfoa and pfas, https://www.amazon.com/dp/B07P1XFYJP

### ⭐⭐⭐⭐⭐ Amazing customer service
*by L***P on December 3, 2025*

I bought this filter in October for an in-progress kitchen remodel. The filter installation was easy, and I'm very happy with the filtration. When I was installing the included faucet on my countertop on Thanksgiving day, I found that the washer, nut, and quick-connect were missing. I contacted Waterdrop customer service via email, not expecting a reply due to the holiday weekend. I was very surprised that, within an hour, I got a personal reply from Karina in customer service. She was very helpful! She sent me a whole new faucet, and it arrived on Sunday, just two days later. Absolutely amazing service from Karina and Waterdrop, and the product itself is to notch. Great flow rate, 3-stage filtration, easily replaceable filters, and a high-quality metal (not plastic) faucet.
