  1. Thanks for this. Down here in Hong Kong, the pollution levels aren’t usually as dramatic as those of Beijing, but they’re certainly nothing to be satisfied with. The willful ignorance of many Hong Kongers and obsession with “ventilation”, coupled with the government’s distorted AQHI which doesn’t reflect international standards, means that people nonchalantly keep windows open when they really shouldn’t. I’m the only foreigner in my workplace and am really struggling with colleagues who insist on windows being open to let in the “fresh” air now that it’s cooling down, which is when the pollution really sets in. I’ve got an air purifier next to my desk, so thanks for giving me some comfort to know that it’s doing something. I’m gearing up for a clash if we have any really bad air days and they still insist on the windows open!

    1. Us foreigners in Beijing contend with the same sort of thing. On even the worst pollution days of the year, a coworker might open the window by my desk. I have had a few nasty arguments about this. I ended up wearing a dust mask while inside the office, because I just can’t be bothered getting into a conflict over it.

      All this, while my company has invested hundreds of thousands of RMB in air purification systems.

      At least it’s not a complete waste, I guess.
