Carbon Filter

Carbon filtration removes chlorine, small solids like sediment, and volatile organic compounds to clean up your water and improve its taste and smell.

What is a Carbon Filter?

Carbon—one of the most enduring elements on our planet—is an amazing natural filter. Carbon has a special ability to bond to different compounds and form long carbon chains, making it effective at trapping unwanted chemicals.

Carbon filters for water filtration are made by grinding up a carbon source—coconut shells, peat, or bituminous coal—and then superheating it to remove impurities. Using hot steam to open up pores in the carbon increases the surface area to which other chemicals can bond.

How Does It Work?

Activated carbon filters—like the one found inside a Wisewell—use a process called adsorption to filter out unwanted compounds from your water. Adsorption (not to be confused with absorption) is when a solid substance attracts other molecules to its surface. Carbon bonds easily and strongly to other chemicals, acting like a magnet for unwanted compounds in a process called chemical adsorption.

However, carbon filters use both chemical and physical adsorption—neutral molecules in water stick to each other through weak electric forces, but carbon’s strong attraction and easy bondability pulls non-water molecules out of the H2O. You can think of the charcoal as a microscopic quality control specialist.

What Does It Remove?

Activated carbon filters remove volatile organic compounds, pesticides, nitrates, hydrogen sulfide, metals, bacteria, viruses, and more. Water treatment plants often use disinfectants like chlorine and chloramine, leaving your water tasting and smelling unpleasant; carbon filters remove these and enhance your water’s taste and scent.

According to the EPA, carbon filters effectively remove the 14 most common pesticides, the 12 most common herbicides, and all 32 identified organic contaminants, including potentially cancerous compounds like chlorine byproducts.
