## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Economical Choice.
*by J***G on February 29, 2024*

Good Quality, Installed Properly and Easily, Provides Good Tasting Water.

### ⭐⭐⭐⭐⭐ They’re easy to use and they work
*by L***C on January 10, 2026*

I’ve been using these filters for years they’re great!

### ⭐⭐⭐⭐ economical, but no relevant certification as per CS.
*by V***A on April 12, 2024*

They fit perfectly fine. I have used several of them for the past 3 years, without any leaks or noticeable issues. Recently as EPA updated guidelines for PFAS in water, I looked for certification of these. I could find none, and customer service confirmed that it has no relevant certification for WD-4035. Lots of other waterdrop products are certified, but this one is not. Not even the basic NSF 43 (aestehtic), let alone 53 (health) or 401 (emerging contaminants). Hence, I discontinued. Original aquasana filters are certified for all 3 standards. And Aquasan filters do feel clearer/better in taste, however this is highly subjective as I am trying to compare my perception of a filter changed just now with the changed filter 6 month ago.
