Carbon is a very versatile and highly effective water treatment medium. It has immense surface area. Approximately half a kilogram of carbon contains a surface area of over 50 hectares (0.5 square kilometers). It is the best known treatment for organic chemicals, volatile organic chemicals, pesticides, herbicides, chlorine and its by-products. It is also an unchallenged taste-and-odor improver. When arranged in solid carbon or extruded carbon block format, it also provides very high quality particulate filtration, in some cases down into the submicron level.

Filter cartridge manufacturers rate cartridges in “microns”. Microns are a size measurement of the pore size, so the smaller the number, the tighter the filter. One-micron filters are for drinking water only. In general, they are too tight to filter large amounts of water without slowing the flow to unacceptable levels.Filter cartridge manufacturers also use the words “absolute” and “nominal” to describe their products’ micron ratings. Absolute means absolute. Nominal means “more or less.”Carbon block cartridges are available in a variety of sizes and flow rates, and effectively provide good general-purpose drinking water filtration.
