Know before you buy
This cartridge is specifically engineered as a direct replacement for the Sundance 75 system. While it is designed for compatibility with Sundance Spas, we recommend verifying your current filter's part number or dimensions against the 17-3/4 inch length and 7-1/2 inch diameter specifications before purchasing.
The 75 sq. ft. rating indicates the total surface area of the filter media available to trap debris. A larger surface area allows for more efficient filtration and longer intervals between cleanings, ensuring your spa water remains clear and sanitary.
For optimal performance, you should rinse your filter with a garden hose every two to four weeks to remove loose debris. Depending on usage, the cartridge should be deep-cleaned with a specialized filter cleaner every few months and replaced entirely every 12 to 18 months to maintain proper water flow and filtration quality.
No tools are required for installation. This cartridge features an open-hole end cap design, allowing it to slide easily over the existing standpipe in your spa's filter housing.
The 3 oz/sq. yd. media weight refers to the density and thickness of the filter fabric. This specific weight is chosen to balance high-capacity debris capture with the necessary water flow rate, preventing undue strain on your spa's pump.
