The Pentek GAC-5 water filters produce healthier, better-tasting drinking water. The Pentek GAC-5 filter has effective bad taste & odor and chlorine taste & odor reduction. The Pentek GAC-5 water filters are designed to allow maximum contact between the water and carbon, ensuring maximum adsorption. The Pentek GAC-5 filter cartridges effectively provide good general purpose drinking water filtration. NOTE: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. NOTE: Cartridges will contain a very small amount of carbon fines (very fine black powder) and a new cartridge after installation should be flushed with sufficient water to remove all traces of the fines from your water system before using the water. Each time you use your filtered water tap for drinking or cooking purposes it is recommended that you run (flush) the tap for at least 20 seconds prior to using the water. The Pentek GAC-5 replacement filter is a Granular Activated Carbon Cartridge. The construction of the Pentek GAC5 cartridge allows water to enter at one end and pass through the entire length of the carbon bed before exiting the other end of the cartridge, while an internal expansion pad minimizes channeling or bypass. Before the water exits the cartridge, a 20 micron postfilter helps reduce carbon fines and other suspended particles from the filtered water. The postfilter is permanently fastened to an innovative support basket ensuring that it is firmly secured and eliminating any potential for bypass.
