    These are the best filters!
  

*by M***R on Reviewed in the United States on May 1, 2022*

I have used a lot of filters over the years for my pond and these are, by far, the best. I am not happy with the price, but everything seems to have gone up.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Quick replacement filters for Therapy Pool
  

*by C***H on Reviewed in the United States on October 6, 2020*

I built a therapy pool in my basement and installed a Hayward filter in the recirculation plumbing to filter larger particles out.  You can clean the filter cartridges, but after one or two times, it time to replace the cartridge.  These fit perfectly and were a pretty good value when you purchase a larger quantity.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Just right

Working great. Easy to clean
