I worked in a building 500 ft from a busy highway and when I cleaned my desk it always had black dust on it.
Along these lines of air quality, can anyone recommend a similarly advanced PM2.5 / PM10 sensor under $100 / ea?

Edit: sorry missed your price guidance. They are quite a bit more so probably not what you're after!
Ikea sells a reasonable air purifier AND seperate sensors nowadays!
It also measures temp/humidity/voc, and has a built-in fan to speed up the response time.
