Carbon filtering is a method of filtering that uses a piece of activated carbon to remove contaminants and impurities, using chemical adsorption . Each piece of carbon is designed to provide a large section of surface area, in order to allow contaminants the most possible exposure to the filter media. One pound (450 g) of activated carbon contains a surface area of approximately 100 acres (40 Hectares). This carbon is generally activated with a positive charge and is designed to attract negatively charged water contaminants. Carbon filtering is commonly used for water purification , but is also used in air purifiers . Carbon filters are most effective at removing chlorine , sediment , and volatile organic compounds (VOCs) from water.

Reverse osmosis systems are generally unaffordable for personal use.
