I bought a top rated air purifier a couple months ago off of the recommendation from Wirecutter. I live in SF, not China, but it's dramatically improved quality of life in my apartment. It cleans out smokey air from cooking very quickly, and cuts down dust/particulates especially in the spring months when pollen is everywhere. Highly recommend.

Just curious, which purifier?

Probably Coway AP-1512HH Mighty.

Yes, the Coway. I've had it for a few months now and just leave it on all the time on auto/eco mode.
