Chemical filters are materials designed to remove specific contaminants from air or water through chemical reactions. They often contain substances that can absorb or neutralize harmful chemicals, such as chlorine or heavy metals. These filters are commonly used in water purification systems and air quality devices to ensure safety and improve overall quality. In addition to their use in household applications, chemical filters are also important in industrial settings. They help protect equipment and maintain environmental standards by capturing pollutants before they are released into the atmosphere or waterways. This makes them essential for both public health and environmental protection.
