Cartridge filters typically last for a few seasons before they need replacement. Some owners keep the old set as a backup or even to use specifically during startup when the pool is at its dirtiest. Instead of exposing your new, clean cartridge to everything in the water after the off-season, use the older grids to deal with the heavy debris.

When the water clears up, remove the older cartridge s , and install the newer ones. A primary indicator that they are going to need replacement is if the bands that secure the pleats begin to fall apart.

That is going to loosen the pleats and reduce the efficiency of the cartridge to filter the water. You might also want to replace the cartridges every three or four seasons prophylactically. It is almost always a good idea to retain the old cartridges as long as they are not falling apart. This way, you have an emergency set for backup that can also serve as a dedicated set for the dirty season. When not in use, simply store them in a cool, dry place. Make sure that they are safe from critters like mice and other rodents who might love to build a nest within them.

And if you feel they are a little bit worn out, your local pool store probably sells products that can help rejuvenate the cartridge. Or you can shop online or ask your swimming pool pro for help.
