Measuring your old cartridge
- Length — cap to cap, with both end caps included.
- Diameter — across the widest point of the pleats, not the end cap.
- End caps — whether each end is open or closed, and the size of any opening.
A variance of ⅛" is normal. Anything larger usually means a different housing model — check the number printed on your old cartridge against the compatible parts list before ordering.

Fit note
Proprietary Excel/Eden retrofit cartridge — fits only after installing the specified conversion kit; not a drop-in OEM replacement.
Before you buy: System 3® retrofit fitment check
- Housing model — confirm the tank label: S7M120 / S7M400 or S8M150 / S8M500.
- Installed conversion-kit version — retrofit cartridges match the conversion kit that is installed, not the tank family alone. Check which kit (and version) is in the tank now.
- Cartridge count — verify how many elements your kit takes before ordering.
- Dimensions — measure the current elements (length, outer diameter) against the specs listed above.

Questions
Fit, replacement & ordering
Still unsure after reading these? Send us the number stamped on your old cartridge and we will confirm the fit.
How do I confirm this cartridge fits my system?
Match the part number printed on your current cartridge against the Compatibility list on this page, or measure the outer diameter, length, and end-cap style and compare them with the Specifications tab. A variance of about 1/8 inch is normal — anything larger usually means a different housing model.
Which filter systems does this cartridge fit?
It fits Sta-Rite System 3 S7M120 (300 sq. ft.), Sta-Rite System 3 S7M400 (400 sq. ft.) when dimensions match. Always confirm against your housing model before ordering.
Is this a genuine Sta-Rite® part?
No — it is an aftermarket replacement cartridge manufactured by Excel Filters in Austin, TX and built to OEM dimensions and media specs. It is not affiliated with or endorsed by the original equipment manufacturer.
How often should I replace my filter cartridge?
Most pool and spa cartridges last one to two seasons depending on bather load and water chemistry. Rinse the cartridge monthly during heavy use and replace it when cleaning no longer restores flow or the pleats show wear.
What if it does not fit my housing?
First double-check the part number on your old cartridge against the Compatibility list on this page — most fit problems trace back to ordering for a different housing model than the listing covers. If you still have a fit question, contact us at (888) 532-2801 and our team will help you confirm the right cartridge before or after you order; returns are handled under our standard return policy.
