We are serious about protecting our students from potentially harmful air pollution.  We have clean air filters in every classroom and all communal areas throughout the school. Even on the highest of pollution days, indoor air quality is better than international health standards.  We maintain our filtration system regularly and always monitor the internal air quality. We have an outdoor play policy based on the best available advice from the US Department of Health, the recognised leader in the field. Accordingly, we take regular readings for the Air Quality Index (AQI) and PM2.5 (the most dangerous particles) throughout the day at four set times, and more regularly where required. When readings exceed the healthy range, students’ outdoor activities are limited or, during any high pollution, cancelled. As our extensive facilities include three indoor gymnasiums and other suitable indoor spaces, many activities are easily able to be transferred indoors. In 2014, the Chinese government developed strict regulations to reduce air pollution in China and since then the air quality has continually improved and the AQI is at its lowest levels in decades.
