An air purifier installed at CentralWorld to combat the PM2.5 situation in Bangkok

The forecast for the cool season: cloudy with a high chance of PM2.5 dust particles. The Bangkok Metropolitan Administration (BMA) is hoping to combat this dire situation by installing a gargantuan air purifier in front of CentralWorld in one of Bangkok’s busiest—and most polluted—business and shopping districts. The stainless steel purifier is four meters in height and 1.5 meters in width, and utilizes a HEPA filter that can purify no less than 17,000 cubic meters of air per hour within a 1,000-square-meter area. The entire project, a collaboration between BMA and Kasetsart University, is still an experiment. If it’s proven successful in reducing the pollution in the area, plans will be in motion to install more purifiers at more locations in the city.
