The Caldera 74817 filter cartridge is a factory-original replacement built for Caldera Utopia® Cantabria® spas. With 100 square feet of filtration across 300 pleats of heavy-duty polyester, it delivers superior water clarity and efficient filtration — so you spend less time cleaning and more time enjoying your hot tub.
Filtration is where water quality is won or lost. Every soak leaves behind 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 is worn or clogged, the effects spread everywhere: dull water, higher chemical use, softer jets, and a pump and heater straining against restricted flow.
This is a large-capacity cartridge with the highest pleat count in the Caldera lineup — a full 100 square feet across 300 pleats, matched to the demands of the Cantabria, one of Utopia’s largest and most jet-heavy models. Caldera specifies a heavy-duty polyester media built to outlast cheaper alternatives, and like all Caldera filters it’s made in the USA.
Pro Tip: Look at the top of your current filter before ordering — it’s the fastest way to know which Cantabria filter you need. Caldera changed this filter partway through 2014. If your existing cartridge has an open hole in the top, this 74817 is your filter. If the top is closed with no hole, you have the newer version and need part 73722 instead. That one look saves a return.
