Fit note
This housing requires three cartridges per housing. 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.
Not sure which kit you have? Contact us with your tank model and a photo of the installed manifold and we’ll confirm fit before you order.

FAQ
Fit, replacement & ordering questions
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 Dimensions and Fit tab. A variance of about 1/8 inch is normal — anything larger usually means a different housing model.
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.
