Which method uses activated carbon to remove impurities from water?

• A. Reverse osmosis
• B. Carbon filter
• C. Distillation
• D. Brita

Answer: (B)

Activated carbon removes impurities through adsorption, where pollutants cling to the surface of the carbon’s porous structure. This makes a carbon filter especially good at reducing chlorine, tastes and odors, and many organic contaminants in water. The device that uses this material to treat water is a carbon filter, which passes water through activated carbon so odors, flavors, and contaminants are captured on its surface. Other purification methods rely on different processes—reverse osmosis uses a membrane to block dissolved substances, and distillation uses boiling and condensation to separate impurities. Some systems, like Brita, use carbon filtration as their primary method, improving flavor and purity through this adsorption process. Remember, carbon filters have limits and need replacement as the carbon becomes saturated, and they don’t remove all types of impurities such as certain minerals or metals unless combined with other media.
