Replacement Filter Cartridges
XLS-831 is the single cartridge for the listed Sundance 120 / 125 double-end application: match 6540-488, PSD125-2000, C-8326 or FC-2780 and confirm the double-end style. XLS-418 fits the Sundance Tacoma 680 using 6000-136. XLS-404 replaces only the short cartridge of the 6000-134 assembly, which also takes a longer cartridge. If your cartridge uses another number, use the cross-reference chart to find its replacement.
Match your Sundance Spas filter housing to the right replacement cartridge.

That assembly takes one short cartridge (C-4401) and one longer cartridge (C-4405). XLS-404 replaces the short cartridge only.
No. A spa brand alone does not establish cartridge fit. If your existing cartridge has a different number or end-cap configuration, use the cross-reference chart or measurement guide to find the matching replacement.
XLS-831 and XLS-418 are supplied as one cartridge and XLS-404 as a 2-pack. Check how many your installed system needs before ordering.
