Assuming that all conditions are perfect and you can get high-quality data from either one.

Which one would I use...

  • If I live alongside a highway and want to know - generally - what's in the air?
  • If I live alongside the highway and want to know - specifically - when it's safe to go outside?
  • If I live near an industrial facility and want to record combustion particles at a particular time?
  • If I don't care about time and want to measure particle size and shape?


Hi there! This wiki page has a lot of information on it about the differences between passive and optical particulate matter monitors.
