### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Did not not Pentek name on part packaging.
  

*by J***T on Reviewed in the United States on April 14, 2023*

Does not appear to be a Pentek part.  Seemed a bit large for the filter but managed to fit in in the housing and get it to seal

    Fixed the problem
  

*by B***E on Reviewed in the United States on May 29, 2022*

They are a little bigger than they should be but if you are careful reattaching the unit it stays in place and works

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars

*by S***R on Reviewed in the United States on November 10, 2022*

Gotta use new o rings or it's tough to remove the filter.  These fit perfectly, unlike others I tried are different sizes.. this fits the big blue filter
