In 2020, the Indian state of Punjab tested large-scale 'smog towers' in cities like Delhi, designed to filter air and provide localized cooling. These towers used fans and water sprays to reduce particulate matter and lower temperatures.

Indian poets and environmental writers like Arundhathi Subramaniam and Tishani Doshi referenced these towers in their work, exploring the intersection of technology, pollution, and urban life in the Anthropocene.
