This is a very neat idea, though I suspect they'll ultimately want a more powerful fan.
Note that high quality air filters also have a carbon pre-filter that gets changed more often than the HEPA filter, and having one ought to make your HEPA filter last much longer, especially in somewhere like Bejing. They also play a part in controlling odors.
This is what I'm currently using and love it to death. Note that the customer photos with the "dirty" filters are actually the carbon pre-filter and not the HEPA

I was curious and just checked the NYC AQI. It's 324 right now, which is classified as "hazardous". Wow.
That would definitely suck. Here on the other side of the country, in the Puget Sound area, we get some bad days of wildfire smoke every year, but I don't think I've ever seen it that high. The highest I recall is around 250.
A good HEPA filter can really help. I use an older version of this [1]. It can generally keep my living room AQI below 10ish. I read that the Whirlpool brand name was sold off to some generic oversees appliance maker several years ago, so I don't know if that one on Amazon is as effective as my 20+ year old one.
