REEPLAR 6541-397 is a 19-inch replacement pool and spa cartridge engineered to restore filtration performance in Sundance 880 and 980 series spas built from 2009 to 2023.

When your Sundance 880/980 spa needs a direct-fit cartridge, the REEPLAR 6541-397 offers a precise-size, high-surface-area option that replaces several OEM and aftermarket part numbers. Designed for older Sundance models (Optima, Maxxus, Aspen, Marin, Cameo, Majesta, Capri, Altamar, Claremont, Kingston), this filter brings back efficient debris capture and easy rinsing without the cost of OEM parts—just be sure to confirm your spa year and measure the element before ordering.

Will this filter fit my Sundance 880 or 980 spa?

It fits Sundance 880 and 980 series spas manufactured between 2009 and 2023. This cartridge is a 19-inch assembly that replaces several legacy part numbers used in those model years.

• Compatible with Claremont/Kingston 980 spas (2015–2023)
• Not compatible with Sundance 880/980 spas manufactured from 2024 onward (they use a 15.5" filter)
• Always measure the installed cartridge length and top/bottom diameters before purchase

How does the REEPLAR 6541-397 compare to original and aftermarket numbers?

This cartridge is a direct replacement for several OEM and popular aftermarket references, so it’s a convenient cross-fit option when original parts are unavailable or expensive.

What are the physical dimensions and filtration features?

The REEPLAR 6541-397 is a two-part cartridge assembly with a larger outer element and an inner core; the combined design yields a high filtration area for trapping fine particles while being easy to rinse.

• Outer element: approximately 19.0" length, 8 3/8" diameter, 2 1/4" OD slip top, 4 1/3" open bottom
• Inner element: approximately 18 3/4" length, 5 1/2" diameter, differing top/bottom openings
• Filtration surface area around 80 sq. ft., trilobal star-shaped fibers for improved debris capture
• Outer element rinsable; inner core is non-rinsable—replace inner if clogged

How should I maintain the cartridge for longest service life?

Routine cleaning preserves flow and filtration efficiency: rinse the outer element, inspect endcaps, and replace the inner core when it becomes saturated or damaged.

• Rinse outer filter regularly with a low-pressure hose to remove trapped debris
• Use a filter cleaner soak periodically for deeper cleaning (follow cleaner instructions)
• Replace inner non-rinsable core when visibly clogged or after extended use
• Inspect fit and seals each time you service the spa to prevent bypass and leaks

Who is this for: The REEPLAR 6541-397 is intended for Sundance spa owners (880/980 families) with models from 2009–2023 who need a compatible, high-area replacement cartridge. It’s ideal for DIY spa maintainers looking for an affordable cross-reference alternative to OEM filters, provided their spa uses the 19" assembly—if your spa is 2024 or newer, choose the updated 15.5" filter instead.
