Abstract: Singapore has been affected by transboundary haze since 1972. Ever since the 3-hour PSI value hit 401 in 2013, it has garnered more attention from the public on the mitigation measures during haze events. The common existing solutions for naturally ventilated spaces are closing windows and doors and/or use air purifier. However, this results in accumulation of carbon dioxide and increase in temperature in the room. In addition, staying in an enclosed space with recirculation of air would lead to poor air quality and thermal discomfort. As such, the objective of this research is to determine a better air filtration system for naturally ventilated space by comparing several air filtration systems such as the proposed FFU, Air Purifier and Air Razor, with regards to thermal comfort, particulate matter removal efficiency and indoor air quality with reference to Carbon Dioxide level. Experiments are conducted in NUS Hostels, namely College of Alice and Peter Tan (CAPT) and Eusoff Hall (EH). Through the experiments, it shows that FFU is a better alternative overall in terms of air change per hour, thermal comfort, acoustical performance, carbon dioxide level. Although FFU consumes slightly more energy than Air Razor, it provides a more comfortable and healthier indoor environment for occupants. The experiment can be expanded to other naturally ventilated areas such as classrooms and old folks home.
