Why do you need an accurate measurement for consumer air quality monitoring? I believe even a DIY arduino project with cheap optical dust sensor, like PPD42NS or GP2Y1010AU0F, would be enough.

Why use a measurement device at all? Your nose is quite good enough, as long as it's neither clogged nor "calibrated" to city air. Putting a dust mask with a P3+carbon filter on for an hour or so tends to fix the latter.
