An active carbon water filter effectively removes impurities, chlorine, odors, and harmful chemicals from water through a process called adsorption. Made from activated carbon derived from coconut shells or coal, these filters trap contaminants while allowing clean water to pass through. They improve taste and clarity, making them ideal for both residential and commercial use. Active carbon filters are commonly used in under-sink systems, water pitchers, and whole-house filtration setups to ensure safe, fresh, and better-tasting drinking water.
