50 Sq. Ft. Cartridge Filter

Caldera Spas 50 sq. ft. cartridge filters are medium‑capacity spa filters used on select Caldera models (including various Paradise, Legacy, and Vacanza‑series hot tubs, depending on year and configuration). They provide 50 square feet of pleated filtration media to keep spa water clear by trapping fine debris, body oils, and other contaminants before they recirculate.
