||NUS adapts household fans to combat haze
The Business Times, 26 May 2014
Household fans can now be used to fight the haze thanks to a filtration system developed by researchers from the National University of Singapore’s (NUS) engineering faculty. The system, which consists of the filter and a cover, converts a fan into an air purifier.
The filter helps remove particulate matter measuring less than 2.5 microns in diameter from indoor air. Such particles, also known as PM2.5, are referred to as “fine” particles and are be lieved to pose the greatest health hazards.
