The Hot Spring Prism 78286 filter cartridge is the factory-original replacement built specifically for the Hot Spring Limelight® Prism. With 260 pleats of heavy-duty polyester media, it delivers more efficient filtration and better water clarity — so you spend less time on maintenance and more time enjoying your spa. Your filter handles the work you never see. Every soak introduces body oils, lotions, hair, and fine debris, and the cartridge is what removes all of it before it clouds the water, feeds bacteria, or coats your plumbing. When a filter wears out or clogs, the symptoms show up everywhere else: dull water, more chemical use, softer jets, and a pump and heater straining against restricted flow. Hot Spring spas are engineered as hydraulically balanced systems — matching filter fabric to water flow — and they filter 100% of the water, 100% of the time. That's precisely why a model-specific, factory-spec cartridge matters: the right filtration area and flow characteristics are what keep your filtration efficient, your jet pressure correct, and your pump running comfortably. Made in the USA from heavy-duty polyester, this filter is built to last considerably longer than generic alternatives. Pro Tip: The Prism uses its own filter — don't assume all Limelight models share one. Other 2018-and-newer Limelight spas (Pulse, Flair, Flash, and Beam) use a different cartridge, while the Prism takes this 78286. If you're ever unsure, pull your current filter and read the part number printed on it. Your old cartridge is the most reliable guide there is. Brand Hot Spring®
