I did this this year for wildfire smoke, and it works great. Having said that, it is not quiet and the way I was using it was to run it at full blast for an hour, then leave it off for most the day.
If you wanted an always-on solution, I think I’d actually suggest a commercial air purifier.
I don’t see what would be wrong with a world where businesses just satisfied themselves with providing employees with a reasonable living, contributed to the communities they were in, and provided a good or service that was needed. Sitting under a tree and reading a book sounds better than watching the world burn in your name-brand clothes and 5 bedroom 2.5 bath house.
