Interpreting CO2 Levels
The CO2 reading is crucial for understanding air freshness. The device uses a color-coded system to indicate CO2 levels:
| Color | Range (ppm) | Rate |
|---|---|---|
| Green | 400 ~ 1000 | Normal |
| Yellow | 1000 ~ 2000 | Slightly High |
| Red | 2000 ~ 3000 | High |
| Maroon | 3000+ | Very High |
When CO2 levels exceed 1000 ppm, it is recommended to open windows to introduce fresh air into the room.
