6540-502S SUNDANCE SPAS 780 MICROCLEAN FILTER

The Sundance Spas MicroClean® Disposable Filter (6540-502S) is the fine-fiber, top-stage cartridge component of a two-part filtration system. It is designed to work in conjunction with a larger, pleated outer filter (such as the 6540-501S) to deliver ultra-fine debris and oil removal that pleated filters can miss. This compact, disposable filter is a key component for providing superior water clarity in many Sundance Spas models.

Key features:

• Dual-stage filtration: It works as the second stage in a dual-stage system, absorbing very fine oils, lotions, and micro-debris that pass through the initial larger filter.
• Disposable design: The microfiber media is not designed to be cleaned. It should be replaced every 3–4 months for optimal performance.
• High efficiency: The spun-bound microfiber material is engineered for superior water polishing and clarity.
• Sanitizer-friendly: The filter media is compatible with all common sanitizer types, including chlorine, bromine, UV, and mineral systems.

The Sundance Spas 6540-502S is compatible with numerous Sundance Spas built between 2002 and 2024, as well as with some Sweetwater Spa models. These include, but are not limited to, the 680, 780, 850, and 880 Series, along with many specific models.
