TL;DR
A cartridge filter is a pool filter that strains water through one or more pleated polyester elements, capturing particles down to roughly 10 to 15 microns, finer than sand's 20 to 40, without the backwashing a sand or DE system requires. Cleaning means pulling the elements and hosing them down every few weeks in season, with an overnight degreaser soak once or twice a year, and replacement cartridges last 2 to 5 years.
What it means
A cartridge filter is a pool filter that strains water through one or more pleated polyester elements, capturing particles down to roughly 10 to 15 microns, finer than sand's 20 to 40, without the backwashing a sand or DE system requires. Cleaning means pulling the elements and hosing them down every few weeks in season, with an overnight degreaser soak once or twice a year, and replacement cartridges last 2 to 5 years. The no-backwash design saves thousands of gallons annually, a selling point in drought-priced water markets. Sizing generous, 100 or more square feet of element per 10,000 gallons, stretches cleaning intervals and keeps pressure drop low.
