The Unicel C-4950 is a direct replacement for the Jacuzzi® J-200 Series 373045 filter, delivering 50 square feet of filtration across 212 uniform pleats. Built to meet or exceed OEM specifications, it’s the kind of replacement that performs like the original — and often outlasts it.
Filtration is the quiet backbone of clean spa water. 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.
What separates a Unicel from a bargain cartridge is what it’s built from. The media is Reemay® polyester — a trilobal fiber whose three-lobed shape presents substantially more surface area than standard rounded fibers, giving the filter higher dirt-holding capacity and more time between cleanings. Add chemical-resistant end caps with an exact OEM fit, uniform pleats spaced for optimal flow, and a solid core that won’t collapse under pressure, and you get a cartridge that holds its shape and its performance through cleaning after cleaning. Made in the USA.
Pro Tip: Uniform pleat spacing is what makes a filter easy to clean. When pleats are packed unevenly, debris wedges into the tight spots and a hose stream can’t reach it — so the cartridge never really comes clean and flow keeps dropping. Evenly folded pleats let water get all the way to the base of each fold, which is why a well-built filter rinses out properly and keeps performing.
