Product Description



  • Our generic replacement cartridges are less expensive than the original manufacturers' brands yet still meet the same high quality standards.  The key components of a cartridge - filter media, core, and end cap - are all designed for maximum water flow and cartridge life.
  • The filter media is point bonded polyester with even fiber distribution which results in an even dirt load and increased water flow.  
  • The Sharp & Uniform pleated media provides filtration area (square footage) that meets or exceeds the original manufacturers' specifications.  
  • An open core design provides sturdy support for the media without restricting flow.  Increased flow rates result in less wear on the pump and reduced energy usage.  
  • Anti-microbial end caps inhibit the growth of bacteria, mold and mildew while supporting the core and media.
  • Banded Pleats maximize flow during operation, and help to reduce the frequency of cleaning.  Banded pleats also make the cartridge easier to clean.

Is this filter the same as the Jandy CJ 250S. I did not see an S with the listed item. Thanks

Yes, this would be the same and is a replacement for the model CJ250S.

Mine has the same dimensions but is only 28 inches tall. Will this filter work? I cant read any of the serial or model numbers.

A  Answered on 10/25/2021 by InyoPools Product Specialist Rich N.

Hi Tom, this will not work.  Look for any part numbers on your current cartridge or send us pictures to upload@inyopools.com of your filter and any labels that are remaining on it as well as pictures of the plumbing going into and out of it and we will be sure to recommend exactly what you need.
