Hot Tub Things 6540-502 Replacement Filter Cartridge for Sundance Spas (2002–2024) | MicroClean Technology

Upgrade your Sundance spa filtration

Hot Tub Things 6540-502 Replacement Filter Cartridge is engineered for compatibility with Sundance Spas from 2002 through 2024, fitting popular models such as Tango, Caprio, Montclair, and Chelsee. The design emphasizes easy installation and reliable performance, helping you maintain clear water after regular soaks and spa maintenance routines.

The outcome is water that looks brighter and feels cleaner, with reduced surface films after typical spa use. This cartridge is compatible with a broad range of sanitizing methods, including chlorine, bromine, UV, and mineral sanitizers, offering flexibility if you switch products over time.
