> The results of the tests are overall promising. They show a very good reproductibility of the measurements between the sensors. They also show an overall very good constitency with the measurements from the official stations of Atmo Nouvelle Aquitaine, better for PM2.5 than for PM10. The full study is downloadable as a .pdf-file on the webpage.

Just putting this here. I’d totally agree with their assessment that the PM2.5 readings are more reliable than the PM10 readings.
