3. Setup
- Unpacking: Carefully remove the air quality monitor and all accessories from the packaging.
- Initial Charge: Before first use, fully charge the device using the provided USB Type-C cable and a compatible USB power adapter (not included). The battery indicator on the display will show charging status. A full charge typically takes several hours.
- Power On: Press and hold the power button (usually located on the side or back) for a few seconds until the display illuminates.
- First Use Data Clear: When using the device for the first time, press and hold the power button until you hear two "beep" sounds. This action clears any initial data and ensures accurate readings from the start.
- Placement: Place the monitor in the desired location, ensuring it is on a stable surface and away from direct airflow (e.g., vents, open windows) or sources of high humidity/temperature, which could affect readings.
4. Operating Instructions
Power On/Off:
- To power on, press and hold the power button until the screen lights up.
- To power off, press and hold the power button until the screen turns off.
Understanding the Display:
The monitor's high-definition color screen displays real-time readings for various air quality parameters. The display typically includes:
- PM2.5, PM1.0, PM10: Particulate matter concentrations in micrograms per cubic meter (µg/m³).
- TVOC: Total Volatile Organic Compounds in milligrams per cubic meter (mg/m³).
- HCHO: Formaldehyde concentration in milligrams per cubic meter (mg/m³).
- CO2: Carbon Dioxide concentration in parts per million (ppm).
- TEMP: Temperature in Celsius (°C) or Fahrenheit (°F).
- HUMI: Relative Humidity in percentage (%).
- Time: Current time display.
- Battery Indicator: Shows current battery level.
- Air Quality Indicator: A color-coded bar or icon indicating overall air quality (e.g., Good, Moderate, Poor).

Changing Temperature Units:
The device allows switching between Celsius (°C) and Fahrenheit (°F) for temperature readings. Refer to the device's buttons or on-screen menu for specific instructions on how to toggle this setting. Typically, a short press of a dedicated button or a menu option will facilitate this change.
Interpreting Air Quality Readings:
The monitor provides real-time data. Consult the Air Quality Pollution Level Reference Table below for guidance on interpreting the measured values and understanding their implications for indoor air quality.
5. Air Quality Level Reference Table
This table provides a general reference for interpreting the air quality readings from your Xoopon AK16 monitor. These values are indicative and may vary based on local regulations and specific health guidelines.
| Parameter | Good (Qualified) | OK | Poor |
|---|---|---|---|
| CO2 | ≤800ppm | >800ppm; ≤1500ppm | >1500ppm |
| HCHO | ≤0.08mg/m³ | >0.08 mg/m³; ≤0.10 mg/m³ | >0.10 mg/m³ |
| PM2.5 | ≤75ug/m³ | >75-150ug/m³ | >150ug/m³ |
| TVOC | ≤0.6 mg/m³ | >0.6 mg/m³; ≤1.5 mg/m³ | >1.5 mg/m³ |
| PM10 | ≤75ug/m³ | >75-150ug/m³ | >150ug/m³ |
Note: When using for the first time, please press and hold the power button until you hear two "beep" sounds, and the display data will be cleared.
