Sofia actively participated in the "European Mobility Week" (16-22 September) by showcasing innovative solutions for cleaner air. One of the focuses was the AeroSolfd project, which aims to transform enclosed spaces such as metro stations into healthier zones. In the autumn of 2023, testing of special air purifiers that filter harmful particles from brake systems began in the Sofia Metro. The results of this pilot study will help develop effective and affordable solutions to improve air quality in the city.
The project is funded under HORIZON Innovation Actions.
