Air pollution due to industrialisation and urbanisation. The Clean Air Tower is a conceptual design envisioned for cleaning the air in overly polluted Chinese cities.

China-based architect Alexander Balchin has designed a building that can clean polluted air. The tower is designed to filter air for several city blocks outside. Dirty air pulled into a central chimney would be cleaned using systems commonly used in coal power plants.

'The PM2.5 particles can be collected and even reused, as they are almost completely carbon,' Balchin writes. 'This process alone provides eight and a half million cubic meters of clean air per year, enough air for one square kilometer of land.'
