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.
  • We carry thousands of generic cartridges to replace all of the most popular OEM brands such as Sta-Rite, Pentair / Pac Fab, Hayward, Purex, American Products, Jacuzzi,  Hot Springs, Coleman, and more.

is this a 10 micron filter and what is the warranty? What justifies this price vs. the other Amazon options at less than 1/2 the price?
