Hot Spring Prism 78286 | Limelight Spa Filter
TheĀ Hot Spring Prism 78286 filter cartridgeĀ is theĀ factory-original replacementĀ built specifically for theĀ Hot Spring LimelightĀ® Prism. WithĀ 260 pleatsĀ of heavy-duty polyester media, it delivers more efficient filtration and better water clarity ā so you spend less time on maintenance and more time enjoying your spa.
Your filter handles the work you never see. Every soak introducesĀ 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 aĀ pump and heater strainingĀ against restricted flow.
Hot Spring spas are engineered asĀ hydraulically balancedĀ systems ā matching filter fabric to water flow ā and theyĀ 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 fromĀ heavy-duty polyester, this filter is built to last considerably longer than generic alternatives.

Hot SpringĀ® Brand FAQs
Who makes Hot Spring spas?
Hot Spring spas are made by Watkins Wellness, a company with more than45 years of hydrotherapy expertise and part of the Masco family of brands. Hot Spring is one of the most recognized and highest rated names in hot tubs, known for legendary massage, easy water care, and leading energy efficiency.
What are the Hot Spring spa collections?
Hot Spring offers four collections. The HighlifeĀ® Collection is the flagship line, with premium design, specialized jets, smart water care, and 100% filtration. The LimelightĀ® Collection features advanced design with targeted jets. The Hot SpotĀ® Collection delivers the essential Hot Spring experience with comfortable jets and a salt system. The FreeflowĀ® Collection offers Plug-N-Play ease with gentle jets. Hot Spring also makes the Vigorā¢cold plunge.
Which filter does my Hot Spring spa use?
It depends on your model and year. Many Hot Spring spas use the Tri-X ceramic cartridge filter, marked P/N 0969601 on the top, while others use polyester (paper) cartridges or the larger filters found in Limelight models. The most reliable way to confirm is to check your owner's manual, or pull your current filter and read the part number printed on it. Also check how many filters your spa takes, since some models use more than one.
How often should I clean and replace my spa filter?
As a general rule, rinse every two weeks and deep clean periodically with a dedicated filter cleaner to dissolve the oils a rinse can't remove. Replacement intervals depend on the type: polyester cartridges are typically replaced aboutonce a year, while a Tri-X ceramic filter can last up to five years with proper maintenance. Replace any filter sooner if the pleats are torn, flattened, or permanently discolored.
Are genuine Hot Spring filters worth it compared to aftermarket?
Factory-original filters are built to the exact dimensions and flow characteristics your spa's filtration and jet pump systems were engineered around. An aftermarket filter that fits the opening may still restrict flow or filter less effectively, which can make your pump work harder and leave your water less clear. Genuine filters are the safest choice for protecting both water quality and equipment.
What makes water care easier on a Hot Spring spa?
Hot Spring builds water care into the spa itself. Many models use the FreshWaterĀ® IQ salt water system, which monitors water hourly and provides clear instructions with Precision Dosing to help keep water balanced with less effort. Combined with effective filtration and a regular cleaning routine, that's what keeps Hot Spring water clear and comfortable with minimal hands-on maintenance.
