Abstract

The increase in outdoor pollutant concentration due to occasional trans-boundary haze is a public health concern in Singapore. During such smoke haze episodes, it was shown that occupants of naturally ventilated spaces could be exposed to pollutant levels that approximate outdoor levels. Closing windows and doors, as advised by the authorities, can reduce the infiltration of outdoor pollutants into such spaces. However, long duration of closure could lead to a build-up of heat and indoor pollutants. We explored the use of two simple fan filter prototype systems as a cost-effective haze mitigation tool. The results showed that by attaching a high efficiency air filter to a fan, outdoor air can be filtered and introduced for ventilation, reducing the build-up of heat and pollutants in a classroom.
