As I mentioned in the article it really depends on the length of the exposure and how you use the sensor.
Yes in many places in Europe or North America, the outdoor air quality is most of the time good.
However -unfortunately- there are also many places where the outdoor air quality is very unhealthy most year round and then an annual exposure to 35 μg/m³ vs 5 μg/m³ makes a big difference.
