A team of researchers from NUS’ Faculty of Engineering has developed a cost-effective solution for the control of indoor air pollution, especially from the haze.
The development of this system is timely in light of the World Health Organization’s (WHO) recent news on the risks of inhalation of particulate matter measuring less than 2.5 microns (PM2.5), which has been linked to a range of cardiovascular and respiratory ailments, including cancer. The new system is easy to use and ideal for use in a range of indoor environments.
Essentially, the invention developed by the NUS team, led by Associate Professor Jeff Obbard from the Department of Civil & Environmental Engineering, is a filtration system that is designed for use with a domestic ventilation fan to remove PM2.5 from indoor air. The system is also able to reduce levels of volatile organic compounds (VOCs) that are typically associated with the odour from haze pollution.
Assoc Prof Obbard said: “In Singapore, we typically spend about 90 per cent of our time indoors, and we have successfully commercialised this research discovery so that everyone can benefit from a cost-efficient way of swiftly and effectively reducing PM2.5 pollutants in indoor air.”
