Frequently asked questions
How often should a filter cartridge be replaced?
Most cartridges are cleaned several times a season and replaced when the pleats no longer come clean, the fabric goes hard or brittle, or the end caps separate. Filter pressure that returns to high shortly after a cleaning is the usual sign that the element is finished.
What is the part number for this filter cartridge?
Sta-Rite lists this filter cartridge under part number 25022-0225S. Quote 25022-0225S when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
How do I clean this cartridge?
Rinse between the pleats with a garden hose, working top to bottom, and soak in a dedicated filter cleaner to remove oils and scale. Avoid a pressure washer, which drives debris deeper into the fabric and cuts the pleats.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Sta-Rite equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
Will this cartridge fit my filter housing?
Cartridges are matched by outside diameter, length, end-cap style and square footage, all of which are listed in the specification section. Compare those four dimensions against your existing element - the filter's brand name on its own is not enough to confirm a fit.
Is there a warranty on this filter cartridge?
It carries the standard Sta-Rite manufacturer warranty. The terms are set by Sta-Rite, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
