Filters

Definition

Filters are devices or materials used to remove unwanted components from a fluid or air stream, improving the quality of the output. In the context of electronic waste and environmental health, filters are crucial for managing pollutants generated during the disposal and recycling processes of electronic devices, ensuring that harmful substances do not contaminate the environment or harm human health.
