Fiber filters are the most common mechanical filters. Carbon-filtering equipment uses activated carbon to collect dissolved organic compounds that cause odors and disagreeable tastes. The typical use of carbon filters is to improve water for drinking and cooking. The longer the water is in contact with the filter, the more time the carbon has to remove impurities. Carbon filters must be replaced regularly to avoid buildup of deposits.
