  • Ametek / Pentek CP-1 Water Filter Cartridges:
  • Pentek Nominal 1 micron Pentek CP-1 Pleated Cellulose Polyester Water Filter Cartridges.
  • The Pentek CP-1 filter cartridge is a special formulation of resin-impregnated cellulose and polyester fibers.
  • The Pentek CP-1 water filter provides higher wet strength than regular cellulose cartridges.
  • The Ametek CP-1 water filters also provide high flow rates and dirt-holding capacity, while maintaining extremely low pressure drop.
  • The Pentek CP-1 water filters have minimal unloading and media migration.
  • The US Filter CP-1 water filter cartridge media is pleated around a polypropylene core for added strength and the ends are immersed in a thermo-setting vinyl plastisol. Embedding and sealing each end of the pleat block in this fashion fuses the components together forming a unitized end cap and gasket.
  • The Pentek CP-1 replacement filter cartridge is not recommended for non-chlorinated water supplies. Cellulose may start to break down if there is bacteria present in well water or other non-chlorinated water supplies.
  • NOTE: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
