Product details

Sta-Rite 25021-0224S is the small replacement cartridge for the System 3 S8M500 filter. It is the genuine Sta-Rite element.

Two cartridges, one filter

The S8M500 runs a large element and a small one together. This listing is the small cartridge. The large one is a separate part number, and it is worth changing the pair at the same time so both elements load and clean at the same rate.

When to replace rather than wash

Cartridges are washable, but not forever. Once a thorough clean no longer brings filter pressure back down near where it starts after a change, the media is loaded past recovery. Torn, matted or collapsed pleats are the other clear signal, and no amount of washing gets those back.

Fitment

Listed for the Sta-Rite System 3 S8M500. Other filters in the System 3 line, including the S7M120, S7M400 and S8M150, take their own cartridge sets, so match the model on your tank label.

Questions and answers

What people ask about this product, answered by our pool techs.

Is this the large or the small cartridge?

The small one. Sta-Rite lists the large cartridge for the S8M500 as a separate part.

Which filter does it fit?

The Sta-Rite System 3 S8M500 cartridge filter.

Should I replace both cartridges at once?

Where a filter uses a large and a small element together, changing both keeps the flow through the pair even and avoids a second teardown a month later.

How do I know the cartridge is done?

When a proper wash no longer brings the filter pressure back down, or the pleats are torn, matted or collapsed, the element has reached the end of its life.
