What Does Carbon Filtration Remove From Water?
Activated carbon filtration is a powerful water purification method. It removes chlorine byproducts such as trihalomethane, which is a cancer-causing substance. Chloramine is a similar chemical that can taint drinking water and kill fish and marine animals. The filter also removes heavy metals like lead, but not fluoride.

Activated carbon is made through a process that involves heating organic material at a high temperature, without oxygen. The result is a porous sponge that has millions of tiny pores. These pores attract contaminants like chlorine, heavy metals, and other chemicals. When water passes through the carbon, the contaminants are attracted to the pores and held on the surface. The pore size determines how many contaminants are able to be removed. Carbon filters are also effective at removing unwanted odors and pesticides.
Activated carbon is considered to be the best way to remove chlorine. However, other contaminants are not easily filtered out of water. These include pharmaceuticals, which can be found in water sources through human waste or improper disposal. These drugs can be prescription or over-the-counter therapeutic drugs. They can also be natural or synthetic chemicals. They can cause a variety of side effects, including a higher risk of cancer.
Activated carbon is also used to remove heavy metals, such as lead. This is because dissolved metals are converted to solid form when they come in contact with the carbon. The filter is also effective at removing cysts, which are tiny, sticky molecules that can be found in water. However, this method is not recommended for the removal of coliform.
Carbon is also effective at removing chloramines, which are chemically similar to chlorine. Chloramines are used as a disinfectant in municipal water treatment systems. However, chloramines are more difficult to remove than chlorine. Chloramines can also cause the water to smell bad and taste bad. It also causes skin irritation and can kill fish and marine animals.
Some carbon filters can remove odors and bad taste. They are also effective at removing VOCs. VOCs are a class of chemicals that are found in air and in water. These chemicals can be very toxic to infants and young children. They can also cause cancer.
Some carbon filters also remove bacteria and cysts. They have pores that are too small to allow these particles to pass through the filter. However, there are some very tight solid carbon block filters that are effective at removing bacteria and cysts. Some carbon block filters are also effective at removing other particles through mechanical filtration.
Activated carbon filters are a popular choice for water treatment. These filters are effective at removing chlorine, chloramines, and other contaminants. This process also helps improve the taste of water. The filter media used is made from coconut, coal, or other organic materials. They are also rated by a third party for safety. The material used in carbon filters is renewable. Carbon is a purer and safer alternative to charcoal. The filter media is used in many different water treatment applications.
