This really doesn't seem like a lot. 1m cubic feet is a 30x30x30m cube. In one day it processes 24 of those. Even if there was no such thing as wind or diffusion and you only needed to treat the 30m of air next to the ground, this "neighbourhood" would only be 150m long and 150m wide for it to be cleaned in a day (as they claim).
TBH I don't rally like Wired's reporting on this kind of stuff. To get an overall view of whether this is useful or not, we need to know:
- lifetime of the pollutant
- air changes per day
- whether this type of pollutant is an important one to tackle
...without that we can't know whether this is just an art project or something practically useful.

Considering it took California decades to clean up Los Angeles air using new technology and regulations, Im pretty sure Beijing residents wouldn't have a problem seeing a pretty, oversized Porta potty every 50 meters if it meant clean air. Taking into account the long term strain on healthcare of polluted air (it makes almost everything worse), this might be an economically viable solution
