65 Sq. Ft. Cartridge Filter

The Caldera Spas 65 Sq. Ft. Cartridge Filter is the ideal replacement filter for many Vacanza Series hot tubs, providing large‑surface‑area filtration to trap fine particles, lotions, and debris before they recirculate through your spa. Swap this cartridge into your Caldera Spa to restore strong water flow, clearer water, and more efficient performance from your heating and circulation system. For best results and longer equipment life, rinse your Caldera 65 sq. ft filter every few weeks, deep‑clean with a filter cleaner every 1–3 months, and replace the cartridge about once per year, depending on bather load.
