Frequently Asked Questions
What filter cartridge does the Hot Spring Jetsetter use?
The Hot Spring Jetsetter uses the PWK30 filter cartridge (also sold as C-6430). Always check the label inside your filter compartment or owner manual to confirm before ordering - part numbers are also printed on the end cap of the existing cartridge.
How many filters does the Hot Spring Jetsetter need?
The Hot Spring Jetsetter uses a single filter cartridge. Confirm by checking the filter housing in your spa - some models in the same series use two cartridges, so it's worth verifying against your specific serial number if you're unsure.
How often should I replace the filter on my Hot Spring Jetsetter?
Most Hot Spring owners replace filter cartridges every 12-24 months, or sooner if water clarity declines despite regular cleaning. Rinse the cartridge monthly by spraying between the pleats at a 45-degree angle, and deep-clean it every 3-4 months with a dedicated hot tub filter cleaner. Replace it immediately if you notice torn or collapsed pleats, permanent brown staining, or a pressure rise that doesn't clear after cleaning.
