Carbon is a substance that has a long history of being used to absorb impurities and is perhaps the most powerful absorbent known to man. One pound of carbon contains a surface area of roughly 125 acres and can absorb literally thousands of different chemicals. Activated carbon is carbon which has a slight electro-positive charge added to it, making it even more attractive to chemicals and impurities. As the water passes over the positively charged carbon surface, the negative ions of the contaminants are drawn to the surface of the carbon granules.


Simple GAC filters are primarily used for aesthetic water treatment, since they can reduce chlorine and particulate matter as well as improve the taste and odor of the water. Loose granules of carbon do not restrict the water flow to the extent of Solid Block Activated Carbon (SBAC) filters.  This enables them to be used in situations, like whole house filters, where maintaining a good water flow rate and pressure is important. Simple, economical maintenance.  Typically an inexpensive filter cartridge needs to be changed every few months to a year, depending on water use and the manufacturer's recommendation.


GAC filters do not require electricity, nor do they waste water. Many dissolved minerals are not removed by activated carbon.  In the case of calcium, magnesium, potassium, and other beneficial minerals, the taste of the water can be improved and some (usually small) nutrient value can be gained from the water. The bottom line is that GAC filters are effective and valuable water treatment devices, but their limitations always need to be considered.  A uniform flow rate, not to exceed the manufacture's specifications, needs to be maintained for optimal performance, and the filter cartridge must be changed after treating the number of gallons the filter is rated for.
