Brand Buying Guide
Identify your Clean & Clear, Clean & Clear Plus, RP, or EasyClean cartridge and match the right replacement.
This guide helps you identify which cartridge your Pentair® filter takes and when to replace it. The housing model — Clean & Clear Plus 420, for example — tells you the cartridge set it runs; the part number on the end cap confirms the exact size.
Have your number? to jump straight to the matching replacement.
Rinse the cartridge with a garden hose every few weeks during swim season, spraying at an angle to flush debris from between the pleats. Deep-clean with a cartridge cleaning solution at least once a season to remove the oils and scale rinsing leaves behind — our care and maintenance guide covers the full routine. Most cartridges last 12 to 24 months: replace yours when cleaning no longer restores water flow, the pleats fray or stay discolored, or an end cap cracks.
Once you know which cartridge you need, shop Pentair® replacement filter cartridges in singles or money-saving multi-packs — engineered to OEM dimensions, made in the USA, and backed by our Perfect Fit Guarantee on listed cross-references.
Check the OEM part number printed on the end cap of your current cartridge, or measure its diameter, length, and both end caps. Every Excel Filters product page lists the Pentair® and aftermarket part numbers it replaces (Pleatco, Unicel, Filbur), and our how-to-measure guide walks through each dimension step by step.
Most pool and spa filter cartridges last 12 to 24 months depending on usage, debris load, and water chemistry. Replace the cartridge when cleaning no longer restores water flow, the pleats fray, or an end cap cracks. Rinsing the cartridge regularly during swim season extends its life.
