Frequently Asked Questions

How do I find the right Pentair® replacement filter cartridge?

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.

How often should I replace my Pentair® filter cartridge?

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.

Are Excel Filters cartridges compatible with Pentair® filter systems?

Yes. Excel Filters replacement cartridges are manufactured in the USA and engineered to meet or exceed OEM specifications for Pentair® systems, with matching dimensions, end caps, and filtration media.

Do Excel Filters replacement cartridges come with a warranty?

Yes. Every Excel Filters cartridge is covered by a 6-month limited warranty against defects in materials and manufacturing, and a 30-day return policy.
