Jandy R0357900 580 Sq Ft Filter Cartridge | Fits CL580 & CV580 Pool Filters

For System 3–style filters, replacing the full inner and outer set is always recommended. Mixing old and new cartridges can cause uneven filtration, pressure imbalance, and faster wear on the new cartridge.

Common signs include rising filter pressure shortly after cleaning, cloudy or dull water, reduced circulation, and cartridges that appear frayed, flattened, or brittle.

The cleaning frequency is contingent on your filter's size. As a general guideline, initiate the cleaning process when the filter pressure exceeds the initial pressure by 10 psi. This ensures optimal filtration efficiency.
