SGAC Cartridges purify water and inhibit the bacterial growth, can be used for longer period i.e., 10,000 Gallons / 3 Years. It is well established that coconut shell based activated carbon and carbon filter cartridges is an effective medium for removing organic compounds that cause objectionable tastes, odours and colors from municipally supplied tap water.
However, the organic compounds that are trapped on the surface of activated carbon filter cartridges become a source of nutrients for bacteria that multiply very rapidly on them in the moist environment of cartridge. Impregnated silver on granular activated carbon in the cartridge inhibits the growth of bacteria within filter beds and prolongs the life of the cartridge many times.
