Typically only work on particulates past a certain size, which won’t deal with many forms of pollution. I’ve heard of some businesses in Beijing using them but even if one is fortunate enough to work at such a place, that leaves the rest of one’s life.
measurably cleaner indoor air
Ah, my old foe: statistical significance. (You can also measure the level of cyanide in your breakfast eggs, doesn’t mean you’re going to be re-enacting Arsenic and Old Lace anytime soon.)
Possibly from the air intakes located on the roof of the buildings. Pollution is much worse on street level than 20 stories up. At least in Jakarta, where I lived for 6 months.
IIRC, the US Embassy’s controversial pollution readings were being taken from their rooftop, and in photos of Beijing you can see the smog in the sky—so the rooftop pollution may still be pretty bad.
If only. Chinese builders do not believe in central air conditioning. Every room gets its own damned air conditioner. Unless your budget is much, much greater than any teacher’s will ever be.
Where exactly would this unpolluted air indoors be coming from?
Filters? Plants? This TED talk comes to mind
