If you plan to use your AirVisual Node/Pro in an area that has no outdoor air quality data from AirVisual world air quality map, you will not be able to see the comparison "Indoor Vs Outdoor" on your device and you will miss the weather and air quality forecast data. Nevertheless, you'll still be able to "see" your indoor air quality for PM2.5 and CO2. Indoor air quality remains the most important component, because that's where you spend 90% of your time.

If you want outdoor air quality readings for your area, you still have the option to install a Node/Pro outdoors and turn it into a public air monitor. See how to make a Node's outdoor data public for your community.
