The VOC Index runs on a scale from 1 to 500:
- A lower number indicates cleaner air
- A higher number indicates increased VOC activity
On the device display, this is translated into simplified air quality levels shown as L1 to L5, which correspond to the five AQI light colors.
| VOC 1-150 | Blue - Excellent |
| VOC 151-275 | Green - Good |
| VOC 276-375 | Yellow - Moderate |
| VOC 376-450 | Orange - Polluted |
| VOC 451-500 | Red - Very Polluted |
