How clean indoor air is becoming China’s latest luxury must-have
The newly opened luxury Cordis hotel looks much like many other high-end hotels in Shanghai, with its glass-sided swimming pool, vast twin ballrooms and upscale spa. But the first Cordis hotel on mainland Chinaboasts something that is genuinely rare in big Chinese cities: clean indoor air. Modest occupancy rates in the megacity’s 5,000-plus hotels mean operators have been desperately competing to attract guests with cheap deals and ever more luxurious features. In a city where air pollution as measured by PM2.5s – tiny particles deemed particularly harmful to health – recently increased 9% year-on-year and now regularly exceeds capital Beijing – one luxury hotel has a new wheeze. All the air that enters the Cordis Hongqiao is passed through two levels of filtration and continuously cleaned, while double-glazed windows remain closed to seal the fresh air inside. Pollution monitors are fitted in all 396 guest rooms and TV screens display PM2.5 levels. Air quality inside the rooms is typically around 10 times better than that outside.
