Air pollution is a major environmental concern in Hong Kong, yet many of us accept it as part of city living and believe that there is not much we, as members of the general public, can do about it.

This is not true, and a game-changing tool is about to change this mind-set.

PRAISE-HK (Personalised Real-time Air-quality Informatics System for Exposure in Hong Kong) is a smart city app that provides state-of-the-science real-time and forecasted (up to 48 hours) air quality and health risk information down the street where you are located. With this mobile app, you will gain convenient access to real-time and forecasted air quality information about your neighbourhoods and surroundings, helping you make informed decisions about your daily activities and reduce your individual exposure to air pollutants.

Key Features of PRAISE-HK:
+ Outdoor real-time air quality information down to the street in Hong Kong
+ 48-hour air quality forecast
+ Forecast videos to understand the interactions between pollutant emission and their transport by the weather systems
+ Interested location bookmarks
+ Health recommendation and push notification of air quality at specific locations
