How do air filters work to remove dust particles?

Air filters work by trapping dust particles and other airborne contaminants as air passes through them. They typically use a combination of physical barriers, such as fibrous materials or mesh, and electrostatic charges to capture particles of varying sizes. The filter's design allows for effective airflow while ensuring that dust and allergens are retained, preventing them from circulating back into the environment. Regular maintenance and replacement of filters help maintain their efficiency in cleaning the air.
