The AirVisual Node/Pro's PM2.5 and CO2 measurements are displayed side by side on the same screen either when the Node is not connected to Wi-Fi, or when no outdoor station is selected. When you select an outdoor station on your Node/Pro to follow via Wi-Fi, this will be displayed next to your Node/Pro's immediate PM2.5 readings on the first screen to clearly display the comparison.

To deselect an outdoor station, go to the Node/Pro's settings menu > Location > Locations list > Remove outdoor location.
