Carbon filters are devices that use activated carbon to remove impurities and contaminants from air or water. The activated carbon has a large surface area with many tiny pores, allowing it to trap particles, chemicals, and odors effectively. This makes carbon filters popular in various applications, including home air purifiers and water filtration systems. These filters work through a process called adsorption, where molecules adhere to the surface of the carbon. They are particularly effective at removing volatile organic compounds (VOCs) and chlorine, improving the quality of air and water. Many households use carbon filters to enhance their drinking water and maintain a fresher indoor environment.
