Activated carbon filtration is a common treatment to remove offensive tastes and odor, color, chlorine and volatile organic chemicals, pesticides and trihalomethanes (a group of suspected carcinogens). Activated carbon will not remove bacteria, dissolved metals such as iron, lead, manganese and copper, or chlorides, nitrates and fluorides.

Activated carbon filters, usually made up of granulated, powdered or block carbon, act like a sponge with a large surface area to absorb contaminants in the water. Activated carbon, made from coal and nutshells, has a tremendous surface area - as much as 125 acres per pound of carbon. The efficiency of an activated carbon filter is dependent on the amount of carbon in it and the flow rate of water through the filter. The typical carbon filter is about 10 inches high and 3 inches in diameter - enough charcoal to treat about 1,000 gallons of water.
