Replacement Cartridges

View Description

Make sure you are ordering the correct part - all replacement parts are final sale.

We have a wide variety of replacement cartridges available for Pentair and Sta-Rite pool filters. These are designed to fit a range of models, and some cartridges may be compatible with multiple models of filter. Nonetheless, it’s important to be aware of the exact cartridge needed for your filter, as design specifications can show subtle variations that can make them incompatible.

Periodically replacing the cartridge in your Pentair pool filter is important. Sometimes they can be gummed up so badly that they can’t be cleaned; when this happens, damage to other pool plumbing, such as the pump and heater, can be a danger. It’s also possible for cartridges to develop tears, which can prevent them from working correctly.
