Granular Activated Carbon (GAC) water filter cartridges are a popular type of water filtration media known to be used to remove a wide range of contaminates from water. These cartridges contain small granules of activated carbon, which is a highly porous material with the ability to absorb impurities onto its surface. Granular Activated Carbon cartridges are effective for improving the odour, taste and overall water quality. Having a large surface area with numerous pores and crevices and as water passes through, contaminants such as chlorines, volatile organic compounds (VOCs), organic chemicals, and certain metals adhere to the carbon surface. This interaction is particularly effective at removing chlorine and its byproducts, which can lead to improved taste and odour of the filtered water. Its versatility can address a wide range of issues making it suitable for residential and commercial applications, being able to reduce and remove various organic chemicals, pesticides, herbicides, and industrial contaminants
