China’s Elite Uses Air Purification Systems And Giant Domes To Retreat From Toxic Urban Air
via New York Times
Levels of deadly pollutants up to 40 times the recommended exposure limit in Beijing and other cities have struck fear into parents and led them to take steps that are radically altering the nature of urban life for their children.
Parents are confining sons and daughters to their homes, even if it means keeping them away from friends. Schools are canceling outdoor activities and field trips. Parents with means are choosing schools based on air-filtration systems, and some international schools have built gigantic, futuristic-looking domes over sports fields to ensure healthy breathing.
Face masks are now part of the urban dress code. Parents have scrambled to buy air purifiers. IQAir, a Swiss company, makes purifiers that cost up to $3,000 here and are displayed in shiny showrooms.
