Haze has returned to Singapore, putting the spotlight on how households can protect themselves from poorer air quality. Hairianto Diman and Susan Ng look at how effective air purifiers are against haze, what to consider when choosing HEPA filters, when filters need replacing and what you can do to improve indoor air quality without a purifier with Prof Liu Zheng, Professor, School of Materials Science & Engineering, and President's Chair in Materials Science and Engineering. They also get an update on the haze situation with Assistant Prof Wang Jingyu, National Institute of Education, NTU Singapore and Principal Investigator, Climate Transformation Programme, at the Earth Observatory of Singapore
