Air pollution has become a global health hazard, with millions of deaths reported annually worldwide, especially in developing countries. At Entiovi, we believe that the key to minimising exposure to air pollution is through awareness and informed decision making. To address this challenge, we have developed Cleair, a hyper-local air pollution monitoring platform that empowers individuals to take control of their exposure to air pollution. Cleair is a simple mobile application that provides users with real-time data on their daily and hourly exposure levels to air pollution. Our platform uses an innovative approach and sophisticated analysis to inform users about pollution level patterns, both temporal and spatial, to help them manage their exposure effectively. We collect data from existing pollution stations, and we have also developed our low-cost sensor-based devices that can be deployed to complement or create a network where none exists. Our team at Entiovi has deep experience and understanding of both the domain and technology. We believe that data is the cornerstone of our approach, and we have invested heavily in identifying relevant data sources and the global benchmarks for air pollution monitoring. Our data scientists and engineers work with our domain experts to develop a unique framework to deliver actionable recommendations for users to manage their exposure.
