Keep your spa water clear and your system running smoothly with the OnCore WSOC.CLD714D-2P cartridge filter (OC-714D). Designed for Caldera 75 (new style) applications, this replacement filter is engineered for dependable flow, strong debris capture, and a secure, leak-resistant fit.

This cartridge features a 7″ diameter, 14 7/8″ length, a swivel handle top, and a 2 11/16″ bottom opening—making it a reliable match when replacing common equivalents like Pleatco PCD75N, Unicel C-7375, and Filbur FC-3964. With 75 sq ft of filtration media, it’s a solid choice for routine maintenance and restoring water clarity.

Manufactured in the USA, OnCore filters are built with durable cores, break-resistant support bands, and robust end caps to help maintain pleat spacing and promote even loading over time—so you get consistent performance between cleanings and replacements.
