Description
The Hot Tub Things® Outer Filter – Part #HTT‑6473‑165S is a high-performance replacement for the Sundance® MicroClean® Ultra outer cartridge, compatible with 850 and 880 Series spas manufactured from 2005 through 2023. Built with heavy-duty spunbond polyester media, it traps debris, prolongs inner filter life, and is easy to rinse clean for extended use. With dimensions that match the original (19.8″ × 8.42″), it delivers full OEM efficiency at a more affordable price. Replace every 4–6 months with regular rinsing for optimal clarity and performance.

Product Description

  • Premium washable outer filter cartridge crafted for Sundance® MicroClean® Ultra systems, matching OEM part #6473‑165S in design and performance.

  • Compatible with Sundance® 850 Series (2005–2023) and 880 Series (2009–2023), including Altamar, Cameo, Capri, Majesta, Marin, Maxxus, Optima, Claremont, and Kingston models.

  • Made from durable spunbonded polyester media that resists fraying and shedding under spa heat and chemical exposure.

  • Core of a dual-stage filtration system—captures larger debris and protects the inner filter—extending its lifespan and maintaining water clarity.

  • Fully reusable; just rinse monthly to restore performance and reduce filter replacement costs.

  • OEM-matching dimensions: approximately 19.8″ length × 8.42″ diameter, with a 2.5″ hole, and offers about 130 sq. ft. of pleated surface area.
