India Today's Pollution Ka Solution campaign highlighted several low-cost innovations aimed at Delhi's air pollution. Students and startups presented a tyre particle collector for buses, Mirza Arif's Pollred device to capture road and tyre dust, and Axel One's Atmos Pole, a solar powered air cleaning streetlight installed at Rajghat. Pawan 3, a multi-layer HEPA filter from Ecosystem Private Limited, targets traffic signals and roadside hotspots. Another notable entry was a microalgae based air purification system from Matiyari Technology Private Limited, deployed at Anand Vihar ISBT. It uses photosynthesis to absorb CO2 and release oxygen. The article does not include performance data, maintenance costs, or how these devices scale beyond pilot sites, so real world impact remains unverified.
