Meet Team Caeli–the runners-up of Imagine Cup 2019 World Championship! Nine out of 10 people in the world breathe polluted air, causing as many as seven million deaths every year, the World Health Organization estimates. The World Bank pegs these premature deaths cost the global economy USD225 billion in lost labor income in 2013. Statistics like these and their own experience living in the vicinity of New Delhi, which has one of the world's worst air quality, led five students from Manav Rachna Institute of Research & Studies in Faridabad to embark on a mission to use technology to tackle the problem. The team, comprising Aakash Bhadana, Ishlok Vashishta, Vasu Kaushik, Dipesh Narwat, and Bharat Sundal, came up with Caeli, a smart anti-pollution face mask and portable nebulizer to help those with breathing ailments like asthma and other chronic respiratory diseases.
