How can I see the PM2.5 concentration in µg/m3 on my AirVisual Pro?

Views:

By default, the Node/Pro displays only the AQI (Air Quality Index). In order to show PM2.5 concentration in µg/m3, go to the center button settings menu > 'Display' > 'Units' > 'PM2.5 concentration' > 'Display'.
The PM2.5 concentration in µg/m3 will then display on the screen below the AQI number.
