- Press the Power button to turn the unit on or off.
5.2 Mode Selection
The unit offers four manual airflow modes and an automatic mode:
- Automatic Mode: The unit automatically adjusts fan speed based on detected air quality (PM2.5 and dust levels).
- Silent Mode: Operates at the lowest fan speed for quiet operation, suitable for nighttime use.
- Standard Mode: Provides balanced purification for everyday use.

5.3 Automatic Operation Logic
In automatic mode, the air purifier intelligently adjusts its power based on the detected level of air pollution:
- High Pollution: If the air quality sensor detects significant pollution, the unit will operate in Strong mode to rapidly purify the air.
- Moderate Pollution: For typical levels of dust or when particles are stirred up (e.g., during movement), the unit will operate in Standard mode.
- Low Pollution: When the air is relatively clean, the unit will switch to Silent mode to maintain air quality with minimal power consumption and noise.
