It fits all standard 10" Big Blue housings and effectively reduces chlorine taste, odors, and suspended particles. With a robust 12,500-gallon capacity and NSF certification, it ensures long-lasting, high-quality drinking water for up to three months per cartridge. Sold in an 8-pack, it’s the go-to solution for professionals seeking reliable, clean water filtration. ## Description Pentair Pentek GAC Series Cartridges effectively reduce unwanted flavours and odors from your drinking water, including chlorine taste and smell. Designed for maximum contact between water and carbon, ensuring optimal adsorption. The structure of the cartridge allows water to penetrate from one end and pass across the entire length of the carbon bearing, while an internal expansion pad minimizes channeling or bypass. Before water leaves the cartridge, after a filter, it helps to reduce carbon penalties and other hanging particles in the filtered water. The filter attaches permanently to an innovative support basket, eliminating any potential for the bypass. GAC Series Cartridges are available in a variety of sizes and flow rates, and effectively provide good general purpose drinking water filtration. ## Features - IMPECTION REDUCTION OF BAD TASTE AND Smellings to provide good general purpose drinking water - Fits ALL 10" Pentair Pentek Big Blue or other 10" heavy duty housings and can replace any 10" x 4.5" carbon filter cartridge - AFTER FILTER Helps reduce CARBON DEVICES and other hanging particles in filtered water - NSF INTERNATIONAL tested and approved for your peace of mind - 12,500 Gallon CAPACITY.
