So you own a Water Filter….
Many people own Water Filters to improve the taste of their Drinking Water. Granular Activated Carbon (GAC) is one of the most common medias for improving taste and odor in water. GAC is actually quite amazing. The structure of GAC is both Macro-porous and Micro-porous. This means that the surface of the GAC has large holes in it, and within those large holes are many many smaller holes. This is important because GAC allows the gases, solids, and even some soluble contaminants in the Water to become trapped inside of its pores. Most other Filtering Medias only trap particles between the pieces of Filter Media. GAC actually traps contaminants within itself, and between the Pieces of Media. GAC also has an enormous capacity for the removal of Chlorine, which is important if you are on most Municipal Water Supplies.
GAC is like most good things, it requires some moderation. Once Carbon becomes saturated it can begin to dump into the Water stream, making the Water worse than ever. So, the regular replacement of GAC media and Cartridges is always important. Many people have GAC filters on their refrigerator water/ice dispensers. After a while the water can start to taste a bit stagnant, if the cartridge isn’t changed on time. In general a good rule of thumb is to change Carbon Cartridges for drinking water every 6 months, for best results. As always this recommendation is not etched in Stone. It really depends on your individual Water quality and Water usage. Secondwind Water Systems recommends the regular replacement of GAC adsorption media, on non-chlorinated water supplies, every 3 years, in order to control the growth of Bacteria across the bed.
