To summarize what is in your air, we have developed a single Air Score that combines VOC and PM readings from the sensor suite in Air Pro. This score can be found on the Air Pro display screen and within the mobile app.
It follows the same basic scheme as the EPA’s Air Quality Index (AQI) but with four levels.
- 0 to 100 is green and below recommended exposure levels.
- 101 to 200 is yellow to represent levels that are elevated but really only a concern for sensitive groups.
- 201 to 300 is red and the range in which most people should consider reducing activity or mitigating the source of pollution.
- Over 300 is purple and indicates severely bad air quality.
Auto Protect mode relies on the Air Score to increase the fan speed. When the Air Score rises, Auto Protect mode will automatically increase fan speed to compensate.
