Description
Keep your Marquis or Cal Spa running at its best with the Unicel 5CH-502, a 50-square-foot replacement filter cartridge that delivers professional-grade water purification. Featuring 197 precision-formed pleats of premium 3-ounce Reemay polyester media, this cartridge captures particles as small as 20 microns for remarkably clear, contaminant-free spa water. The sharply defined pleat profile promotes maximum water throughput while keeping pressure drop to a minimum. A sturdy plastic end cap and 2-inch male thread/MPT connection make installation and removal fast and straightforward, while the cartridge’s robust build ensures it performs reliably across many cleaning cycles before needing replacement.
