How to confirm this is your filter

Pull your current cartridge and measure it end to end, including any handle, and across the widest point of the pleats. This cartridge measures 7" in diameter and 17-11/16" long, with a 3" / open w/ step on top and a 3" / open w/ step on the bottom. The bottom fitting matters most: a cartridge with the right diameter but the wrong thread or open-end size will not seal in the filter housing, letting unfiltered water bypass the media.

The 60 sq ft rating describes the pleated media area. Jacuzzi housings are designed around a particular cartridge, so choose a replacement with the same size and fittings rather than a larger area rating. Unicel C-7306 and Pleatco PJB60 are cross-referenced to each other in the Pleatco 2023 catalog, so either should fit the same housing.
