When you say surface dust is unaffected I assume you mean the dust that’s already settled prior to getting a purifier right? If I were to use an air purifier I’d need to dust surfaces less often right?
Comment on Do air purifiers really reduce dust much?

- Only dust in the air that passes through it
- Only if the filter is maintained
- Surface dust is unaffected
Its a noticeable amount, but not likely all of it

Depends on what the air purifier was filtering. Mine does PM10, PM2.5, VOC and NO2. That means it’s filtering out particles down to 2.5mm plus volatile organic compounds (smoke, aerosolized oils, water vapour with pathogens, etc) and nitrous oxide.
The filter is a multi stage filter; the PM2.5 stuff passes right through the PM10 filter.
Interestingly, if I want to clear a room of smoke, sawdust, drywall dust or similar, what works the best is running my shop vac with a HEPA filter installed until I can’t smell the dust (usually around 5 minutes) and then I turn my air filter on full blast and it clears up the air in around 20 minutes. If I just ised the air filter, I’d probably clog it up and then just have to replace the comparatively expensive filter.

Should probably point out that "mm" in this case is micrometers, not millimeters.

Do you have a recommendation for a budget one?

No; however, you essentially have a line between price and noise, and you need to check what they filter, how expensive the filters are, and how often they need to be replaced, as well as how much it costs to run them.
