The most common everyday use of activated charcoal is to filter water.

It improves water clarity, diminishes unpleasant odors, and removes chlorine.

It is used in water filters, medicines that selectively remove toxins, and chemical purification processes.

Activated charcoal is carbon that has been treated with oxygen. These tiny holes give the charcoal a surface area of 300-2,000 m/g, allowing liquids or gases to pass through the charcoal and interact with the exposed carbon.

The carbon adsorbs a wide range of impurities and contaminants, including chlorine, odors, and pigments.

Other substances, like sodium, fluoride, and nitrates, are not as attracted to the carbon and are not filtered out.

Because adsorption works by chemically binding the impurities to the carbon, the active sites in the charcoal eventually become filled.Activated charcoal filters become less effective with use and have to be recharged or replaced.Question: What Is Activated Charcoal and How Does it Work?Answer: Activated charcoal (also known as activated carbon) consists of small, black beads or a solid black porous sponge.

It's not effective for removing certain toxic organic compounds, significant levels of metals, fluoride, or pathogens.
