Charcoal filters are used in a variety of fashions. The most common purpose for using a charcoal based filter would be to eliminate impurities. Gas mask are a good example of how charcoal filters provide protection to individuals by eliminating the impurities (chemical warfare, police riot squads, etc..). Charcoal filters are used in the purification process of many liquids (water processing facilities, coffee machines, aquariums, etc..). Charcoal filters are used in air conditioning units and exhaust fans to rid air of unwanted odors (smoke, fumes, and animal odor). Some forms of alcohol, such as whiskies, are put through various forms of charcoal filters, either before or after aging. The process is known as “leaching” (Removal of materials by dissolving them away from solids). Charcoal filters come in different forms such as solid carbon, impregnated foam materials, powder and cloth (The Flatulence Deodorizer).
Charcoal is carbon & Activated charcoal is charcoal that has been treated with oxygen to open up millions of tiny pores between the carbon atoms.
The use of special manufacturing techniques results in highly porous charcoals that have surface areas of 300-2,000 square meters per gram. These so-called active, or activated, charcoals are widely used to adsorb odorous or colored substances from gases or liquids.
The word adsorb is important here. When a material adsorbs something, it attaches to it by chemical attraction. The huge surface area of activated charcoal gives it countless bonding sites. When certain chemicals pass next to the carbon surface, they attach to the surface and are trapped.
Activated charcoal is good at trapping other carbon-based impurities ("organic" chemicals), as well as things like chlorine. Many other chemicals are not attracted to carbon at all -- sodium, nitrates, etc. -- so they pass right through. This means that an activated charcoal filter will remove certain impurities while ignoring others. It also means that, once all of the bonding sites are filled, an activated charcoal filter stops working. At that point you must replace the filter.
