Product Overview
The Unicel C-9403 150 sq ft Clearwater Cartridge Element is a service replacement filter for pool and spa filtration systems that specify a 150 square-foot cartridge. Its pleated synthetic media design maximizes surface area to trap suspended solids as water flows through the filter housing, reducing debris load on pumps and contributing to clearer water quality. The increased dirt-holding capacity helps extend time between cleanings and supports efficient overall system performance.
Constructed from media and end-cap materials engineered to withstand prolonged exposure to treated water and sanitizers, the C-9403 delivers reliable filtration through multiple maintenance cycles. Routine replacement of the cartridge element is key to maintaining optimal filtration efficiency, balanced water quality, and proper circulation in residential and commercial aquatic systems.
