Changing your Jandy PAJNCS100-4 pool filter cartridge on a regular basis may be necessary to maintain a swimming pool with clear, clean, sparkling and balanced water. If the pool filter cartridge becomes too worn and difficult to clean, it is time to replace. Look for tears, wear, wore out media every time you clean the cartridge and replace as needed.
