Particulate filters are devices designed to capture and remove tiny particles from gases or liquids. They are commonly used in various applications, including automotive exhaust systems, where they help reduce harmful emissions by trapping soot and other pollutants. This process improves air quality and complies with environmental regulations. In addition to vehicles, particulate filters are also found in industrial settings and household appliances, such as vacuum cleaners and air purifiers. These filters enhance the efficiency of these devices by ensuring that clean air is released back into the environment, contributing to better health and safety for users.
