In modern cities, electrostatic precipitators are key to improving environmental quality. As catering - related air pollution grows, these devices use advanced technologies to filter harmful substances in fumes, reducing particulate matter and harmful gases. They enhance the green image of the catering industry, as cities encourage their installation with policies. Widely adopted, they have improved residents' living environments. In the push for carbon neutrality, their low - energy - consumption operation helps cut emissions. By integrating pollution control, corporate responsibility, and urban governance, electrostatic precipitators are shaping a sustainable urban future.
