Huge congratulations to Pongtanawat for being honored with the Bronze Award at the International Trade Fair for Ideas, Inventions & New Products (iENA) 2022! The award was given to the work on the new type of air filter, which incorporates a HEPA filter and carbon materials infused with Ag nanoparticles. The filter effectively removes PM2.5 particles and volatile organic compounds, while also suppressing germs from air.
