The new version of the HEI has the aim of enhancing health risk communication and to better inform and assist members of the public in the interpretation of air pollution levels.
PRAISE-HK – A Personalised Real-Time Air Quality Informatics System for Exposure – Hong Kong (PRAISE-HK) is a new app by scientists from the Hong Kong University of Science and Technology (HKUST). This app helps people access real-time, location-specific air pollution information. It provides personalised sensitivities assessments, recommendations for cleaner routes, personalised alerts, and forecasts to help you plan ahead.
PEEKair Concepts - PEEKair is an indoor air quality monitor, designed specifically for Hong Kong.
