7 13/16" diameter, 22 13/16" long, 111 ft² of media (end caps — top: Closed End, bottom: 4" Open End). Matching measurements alone do not prove a fit: some of our cartridges share a size and differ in filtration area or end caps, so check the part number on your old cartridge too.
No. The XLS-787 is an independently manufactured replacement cartridge, made in the USA by Excel Filters and built to match the Jacuzzi 42379923 specification. Jacuzzi is a trademark of its owner, used only to show compatibility.
Most pool and spa cartridges last 1–2 seasons with regular rinsing. Replace it when cleaning no longer restores flow, the pleats fray, or the end caps crack.
