Fake and made up air quality data
The data is simply wrong, probrably made up. They try to make them convincing by using meteoroligical data such as wildfire position, and provide fake measurements extrapolated from those info. It's a commercial operation to sell you some Air Quality device, nothing scientific. The Atmo website (funded by french government) have proper data that are in complete contradiction with the ones of IQAir. If you're in france, use that.
