An activated carbon filter is a filtration device used to remove impurities, contaminants, and odors from air or water. Made from carbon materials like coconut shells or coal, it undergoes activation, which creates tiny pores that increase its surface area. These pores trap particles and chemicals, such as chlorine, volatile organic compounds (VOCs), and certain gases, through a process called adsorption. Activated carbon filters are commonly used in water purifiers, air purifiers, and industrial applications to improve quality and safety. They are also effective in reducing bad smells and improving taste in water. Eco-friendly and efficient, activated carbon filters play a key role in environmental protection, enhancing air and water quality.
