5. Operating Instructions
5.1 Understanding the Display
The monitor's display provides real-time readings for various air quality parameters:
- PM2.5, PM1.0, PM10: Particulate Matter concentrations in micrograms per cubic meter (µg/m³). These indicate the levels of fine inhalable particles.
- TVOC: Total Volatile Organic Compounds in milligrams per cubic meter (mg/m³). These are gases emitted from certain solids or liquids.
- HCHO: Formaldehyde concentration in milligrams per cubic meter (mg/m³). Formaldehyde is a common indoor air pollutant.
- CO2: Carbon Dioxide concentration in parts per million (ppm). High CO2 levels can indicate poor ventilation.
- TEMP: Temperature in degrees Fahrenheit (°F) or Celsius (°C).
- HUMI: Humidity percentage (%).
- Time: Current time display.

5.2 Interpreting Air Quality Levels
The device provides a 6-grade air quality level indicator based on the current Air Quality Index (AQI) for PM2.5:
- Good: Air quality is satisfactory, and air pollution poses little or no risk.
- Moderate: Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
- Poor: Members of sensitive groups may experience health effects. The general public is less likely to be affected.
- Unhealthy: Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
- Severe: Health warnings of emergency conditions. The entire population is more likely to be affected.
- Hazardous: Health alert: everyone may experience more serious health effects.
5.3 Unit Selection (Temperature)
The temperature unit can be switched between Celsius (°C) and Fahrenheit (°F). Refer to the device's on-screen menu or dedicated button (if available) for this setting. Typically, a short press of a specific button or navigation through a menu option will allow you to toggle the unit.
6. Maintenance
6.1 Cleaning the Device
To ensure accurate readings and prolong the life of your monitor, keep it clean:
- Wipe the exterior of the device with a soft, dry cloth.
- Do not use abrasive cleaners, solvents, or immerse the device in water.
- Ensure the sensor vents are clear of dust and debris. Do not insert any objects into the vents.
6.2 Sensor Care
The sensors are delicate components. Avoid exposing the device to extreme temperatures, high humidity, or direct sunlight for extended periods. Do not attempt to open the device or tamper with the internal sensors, as this will void the warranty and may damage the unit.
7. Troubleshooting
If you encounter issues with your AIROASIS AK16 monitor, please refer to the following common solutions:
- Inaccurate Readings: Ensure the device is placed in a well-ventilated area, away from direct drafts, heat sources, or strong chemical fumes. Allow the device to stabilize for a few minutes after powering on. Ensure the battery is sufficiently charged.
- Device Not Powering On: Check if the battery is charged. Connect the device to a power source using the USB Type-C cable and try again. If the issue persists, contact customer support.
- Display Not Working: Ensure the device is powered on and fully charged. If the screen remains blank, try restarting the device.
- Short Battery Life: Ensure the device is fully charged before use. Battery life can vary based on usage patterns and environmental conditions.
