Cartridge filtration is BETTER filtration than sand and provides roughly twice as file filtration than that of sand.  When water passes through a cartridge filter, the dirt particles are screened out.  It is important to clean the cartridges on a normal basis as accumulation of dirt on the outside of the cartridge can drastically effect the efficiency and effectiveness of the filter.

Generally, for cleaning the cartridge is removed, soaked in Tri-Sodium-Phosphate then sprayed off with a hose.
