The Beijing Jingxi International School dome combats smog in Beijing to provide a clean-air environment for the school's students. The air purification system in the dome filters out particles 2.5 micrometers in diameter. The EPA designates these as "fine" particles that are believed to "pose the greatest health risks. Because of their small size (approximately 1/30th the average width of a human hair), fine particles can lodge deeply into the lungs."
Location: Beijing, China
