KleenWater KW4520BR Dirt Rust and Sediment Pleated Water Filter Replacement Cartridge

This replacement cartridge is constructed of pleated polyester which benefits the consumer in two ways. The pleated design provides a very large exposed surface area that gives the cartridge impressive solids-holding capacity. This cartridge is a single membrane which allows for occasional cleaning. Its performance is commensurate to the competition at a lower cost.
