Polyspun Sediment Filter Cartridges 20" x 4.5"
The Polyspun Sediment Filter Cartridges 20" x 4.5" are replacement cartridges for compatible whole-house water filtration systems. They are intended for customers who already own a suitable 20" x 4.5" system and need sediment filter cartridges for regular maintenance.
Designed for Sediment Filtration
Polyspun sediment cartridges are commonly used as an early filtration stage to help reduce visible particles such as sediment, sand, silt and rust before water passes through later filter stages. Replacing this cartridge on schedule helps support system flow and ongoing filtration performance.
