Cotton is a rough, ribbon-shaped fiber with a large surface area. As such, cotton has a high dirt-holding capacity and makes an excellent filter media.

We processed cotton is an all-bleached, natural fiber with no finish. The recommended operating temperature is 121°C. All materials in our cotton cartridges meet the requirements for applications that fall under Food and Drug. No taste or odor is imparted by the cotton fiber.

All cotton wound Cartridges provide true depth filtration through hundreds of tapered filtering passages of controlled size and shape. The diagonal winding of roving on a center core makes a firm interlocking weave that results in a cartridge that prevents channeling and by passing, and greatly reduces fiber migration. As the cartridge is wound, each layer of roving is napped to increase filtration capabilities. As a result, each layer of roving adds its contribution to true depth filtration by trapping its share of particles. In addition, the irregular outer surface helps prevent surface blinding and helps to assure longer cartridge life and full cartridge utilization. Wound cartridges offer a gradual pressure increase during cartridge life versus surface-type media that have an abrupt flow cut-off when loaded.
