Carbon filter systems are a widely used technology in areas such as water purification and air purification. These systems use activated carbon to remove contaminants and unwanted substances from water or air. In water purification systems, carbon filters are often used to clean drinking water in homes. Activated carbon absorbs chlorine, organic chemicals, pesticides, pharmaceuticals and other pollutants in water. In this way, water becomes cleaner and safer. In air cleaning systems, carbon filters are generally used to absorb air pollutants and bad odors. Chemical compounds, gases and odors in the air are trapped by activated carbon and the cleaned air is returned to the environment. Carbon filter systems are considered an environmentally friendly and effective cleaning method. However, filters may need to be changed regularly because over time they become saturated, absorbing pollutants. These systems are commonly used in homes, workplaces and industrial facilities to improve the quality of drinking water and indoor air.
