The Sundance® 680™ Series MicroClean Mini Outer Filter Cartridge (6473-249S) is a genuine OEM replacement engineered for Sundance 680 Series spas manufactured in 2023 and later, including the Ramona, McKinley, Peyton, Edison, Prado, and Alicia models. This pleated cartridge occupies the outer filtration position, capturing debris, oils, and contaminants as small as 10–15 microns before water reaches the inner filter stage.
Built from high-grade pleated polyester media around a rigid internal core, this filter is designed to hold its shape and maintain steady water flow through repeated cleaning cycles. It measures 14.875″ x 8.375″ x 8.375″ and weighs 1.2 lbs, matching the factory specification for a secure fit inside the 680 Series filter housing.
The outer filter works alongside your spa’s inner filter (6473-283S) to provide dual-stage filtration, so water stays clearer between chemical treatments. Rinse it every 2–4 weeks and plan to replace it approximately every 12–18 months, depending on bather load and water chemistry, to keep filtration performance and water clarity at their best.
