The Pentek CRE-1 Ceramic Water Filter Cartridge is specially designed for cyst reduction and fine sediment filtration applications. The filter cartridge 1/2" thick ceramic wall allows for many cleanings, extending cartridge life. The water filter cartridges are manufactured from a sintered ceramic filtration media. CRE-1 filters are designed and tested for the reduction of Cryptosporidium and Giardia cysts, and are ideal for fine sediment filtration applications. The fine ceramic media will effectively trap dirt, sediment and cysts, down to 1-micron in diameter. A proper fit is ensured and water bypass is prevented through the use of a knife-edge seal. These water filters are easily cleaned with water and a damp cloth, sponge or stiff nylon brush. Pentek CRE-1 filter cartridges can be cleaned several times until the diameter at the smallest point is 1-1⁄2" or the circumference is 4-3⁄4", extending cartridge life. NOTE: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. These cartridges are specifically designed for sediment filtration and the reduction of Giardia and Cryptosporidium cysts, not to kill or filter bacteria. NOTE: Performance depends on system design, flow rate, feed water quality and certain other application conditions. NOTE: Only a thin layer of ceramic is removed with each cleaning. It is not necessary to clean the cartridge until the original color is restored as water in some locations may stain or discolor the ceramic. Good hygiene and housekeeping practices should always be used when cleaning the Pentek CRE-1 cartridge.
