About Cleair

Cleair empowers communities with air quality management in local neighbourhood. Cleair helps communities take active part in understanding their environment by providing hyper-local measurements to enable intervention at a localized level. By identifying key local pollution sources, Cleair enables the design & development of localised control prescriptions and builds community awareness.
Cleair provides the framework, materials & data intelligence for real time local pollution data, helping with coordinated policy formulation that align with global climate change measures.
Cleair helps communities make informed decisions on their day to day activities: suitable time for children to be outdoors or alternative bus stops to avoid heavy pollution. Combining the local air quality data with external data such as traffic & weather information, Cleair uses machine learning to guide on the nearest ‘cleanest’ & ‘greenest’ zones.
