Cartridge filtration has been available for a relatively long time, but has only recently begun to enjoy rapid growth and acceptance. Cartridge filters have a greater surface area than sand allowing for fewer clogs and easier maintenance. Cartridge filters are designed to run at lower pressure than sand which puts less backpressure on the pump, providing more flow and turnover. Cartridge filters should be cleaned once or twice a season by simply hosing them off. Cartridge element filters trap debris as small as 10 to 15 microns.
