A carbon filter, also known as an activated carbon filter or charcoal filter, is a widely used filtration system in homes for water treatment. It utilizes activated carbon, a highly porous form of carbon with a large surface area, to remove impurities from water.
Carbon filters are often used as part of a comprehensive water treatment system in combination with other filtration methods, such as sediment filters or reverse osmosis systems, depending on the specific water quality concerns and desired purification level.
