## Customer Reviews

### ⭐⭐⭐⭐⭐ great value
*by S***R on November 8, 2024*

Works great in my water feature syystem

### ⭐⭐⭐⭐⭐ Quality filter for hard to find part.
*by S***M on June 22, 2023*

I have used a few different filters they've all been subpar. This one on the other hand is working beautifully it fit exactly like the original. I like the extra pleating and just the way it fits it is very close to the original PA225.10/10 will buy again. Please do not stop making these.

### ⭐⭐⭐⭐⭐ Great for older Hayward systems
*by S***. on August 5, 2025*

Great fit for my old Hayward cartridge filter housing. Does well filtering large media while still allowing for ample water flow. No complaints.
