What are Carbon Filters and Activated Carbon Filters used for?

• A. Filtering water only.
• B. Filtering air only.
• C. Filtering minerals from water.
• D. Filtering air & water.

Answer: (D)

Carbon filters and activated carbon filters work by adsorption, using the huge surface area and porous structure of activated carbon to trap dissolved chemicals. In air, this makes them excellent for pulling out odors and chemical contaminants such as volatile organic compounds and pollutants, improving indoor air quality. In water, the same adsorption process removes chlorine, many organic compounds, tastes, and odors, helping to improve taste and reduce chemical residuals. They aren’t designed to remove minerals from water, which is why mineral removal isn’t their purpose. Because they target dissolved chemical contaminants in both media, they’re used for filtering both air and water.
