Cartridge filters use a paper-type cartridge as the filter media. They do not filter as finely as DE, and in our experience produce about the same water quality as sand filtration.
Cartridge filters used to have a bad reputation as a nuisance to maintain, but manufacturers have come up with newer filters with enough surface area (300-500 square feet) to need cleaning only once or twice each year. This makes the maintenance issue a plus with these filters.
