> ...it's interesting to look at the effects of every day tasks.
I suspect pretty much every task elevates PM levels.
I made a somewhat surprising and definitely unwelcome discovery by turning off the lights in my bathroom, flushing, and shining a green laser pointer around (Rayleigh/Tyndall scattering, etc.). Followed up with the same test while scuffing my feet on carpet and doing a few other everyday activities.
It was interesting, so I'd recommend trying it at home, but not right before dinner. Or breakfast. Or ever, if you have an overly vivid imagination.
I dunno. I'm not really convinced that all particulates are automatically harmful at modest levels, at least not to a degree that is worth worrying about. The stuff that worries me are aerosolized modern pollutants- things like smog, glass dust from cutting fiberglass (particularly nasty stuff), and in the future potentially even new wonder materials like carbon nanotubes.
An air purifier with a HEPA filter and an ionizer will take care of the majority of visible airborne household dust, if it really bothers you.
