It’s a dynamic timer displayed on the purifier’s control panel that:
- Calculates the estimated minutes remaining until the air is clean
- Continuously adjusts in real-time based on sensor data (e.g., PM2.5 levels)
- Counts down to zero as the air quality improves
| Element | Description |
| Timer Display | Shows countdown (e.g., 15 min, 8 min) based on pollution levels |
| Sensor-Driven Adjustment | If air quality worsens, the timer may increase; if it improves, it decreases |
| “Air is clean” Confirmation | When the timer hits 0, the display shows a checkmark and “Air is clean” |
