The Hot Tub Things® Inner Filter – Part #HTT‑6473‑164S is a precision-engineered replacement for the Sundance® MicroClean® Ultra inner cartridge—designed to deliver superior water clarity through dense microfiber filtration. Engineered for legacy compatibility with 850 and 880 Series spas (2005–2023), this OEM-level part helps capture ultra-fine pollutants and protects spa systems. Its tool-free installation streamlines maintenance when paired with the MicroClean® Ultra outer filter. Regular replacement every 3–6 months keeps your spa running efficiently and sparkling clean.

Product Description

Provides a direct replacement for the OEM Sundance® MicroClean® Ultra inner filter—densely spun-bound polyester microfiber media captures ultra-fine particles and preserves spa clarity.

Fully fits original part #6473‑164S—aka AK‑6473164 or SD‑01293—in Dual‑Stage MicroClean® Ultra setups; outer filter sold separately.
Dimensions are approximately 18.74″ length × 5.63″ diameter, with open 2.75″ top and bottom holes for precise installation.
Non-washable; replace every 3–6 months based on usage to maintain optimal water clarity and avoid strain on spa components.
