## Customer Reviews

### ⭐⭐⭐⭐⭐ Great replacement filters
*by A***M on August 15, 2022*

These work great. Keep them clean and dry when not in use and they should last a very long time. I left my old ones in the vac too long at the bottom of the pool and they pretty much stopped working, so I had to buy these. They're the same as the ones you get when you buy a new vac. They filter all the small things really well. Bonus points if you get the Blink-182 reference.

### ⭐⭐⭐⭐⭐ Good product fast delivery
*by M***N on July 22, 2024*
