The Pentair Pentek CRE-1 Cartridge* is manufactured from a sintered ceramic filtration media. It is designed and tested for the reduction of small particles, and is ideal for fine sediment filtration applications.
The fine ceramic media will effectively trap dirt, sediment and small particles down to 1 micron in diameter. A proper fit is ensured and water bypass is prevented through the use of a knife-edge seal.
Pentek CRE-1 Cartridges are easily cleaned with water and a damp cloth, sponge or stiff nylon brush. They 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.
