Granular Activated Carbon (GAC) water filtration system is one of the most prevalent kitchen filtration systems. There are a large number of brands and manufacturers providing varying benefits depending on the number of filtration system steps. The GAC filters operate through raw organic carbon material, which is activated through heat. Once activated then, the contaminants are removed from the water.
The advantages of the GAC filter are its affordable price alongside its ability to remove the majority of water contaminants, even chlorine and pesticides.
The major drawback of the GAC filter is that it is a cartridge-based filter and will require maintenance, such as changing the filter cartridge. GAC can remove the large majority of the water contaminants, but one place it may fall behind is its inability to filter through heavy metals.
