Product Description

The Sundance® 6540-481 filter cartridge is a 65 sq ft pleated media filter designed for long-lasting performance in various Sundance® Spas.
It measures 7½″ in diameter and 14-¾″ in length with a 2⅝″ (2.62″) open inner diameter at the base.
The top is typically closed (castle / solid top) while the base allows water to flow through the inner core.
Common equivalent filters include Filbur FC-2740, Unicel C-7466, PSD65-2, and others.
It traps debris, oils, and fine particles to preserve water clarity, protect pumps, and maintain system flow.
Many users clean and reuse this filter across multiple service cycles before full replacement is needed.
