PM2.5 Monitor
The PM2.5 sensor can measure the volume of PM2.5 in nearby area and display the actual measurement on the
real-time monitor. The air quality will also be analyzed and categorized into 4 grades, which are “Excellent”,
“Good”, “Moderate” and “Bad”.
Gas Monitor
The Gas sensor can detect the existence of gas pollutants in nearby area, the air quality toward gas pollutants
will also be analyzed and categorized into 4 grades, which are “Excellent”, “Good”, “Moderate” and “Bad”.
Air Cleanliness Halo
The PM2.5 and Gas Monitor also equipped with Air
Cleanliness Halo, the Halo will change in color to illustrate 4
different grading of air cleanliness as below:

Excel ------------------------------ Blue

Good ------------------------------ Yellow

Mod ------------------------------ Orange

Bad ------------------------------ Red
Air Volume Monitor
The Air Volume Monitor shows the current output flow rate and the flow rate of the selected mode.

Note:

The sensors will initialize after the first time of the unit is being connected to the power supply; or being
turned on again after the unit is not in used for a period of time. The process of initialization will take 2-5
minutes to complete. After this process is completed, the PM2.5 and Gas indicator will light up
automatically.

As default, the SMART mode will active when the unit is being turn on.
Note ：

The gas sensor is not designed to detect a specific type of gas pollutant. When user measures a specific
type of gas pollutant such as formaldehyde, the result of measurement may differ from the unit’s sensor.
If strong odor is smelled, Quick mode is suggested to activate for fast purification.

The measured value of PM2.5 from the unit is for reference only; the precision of the sensor can be
interfered by other appliances, such as humidifier. When the fan switches between high to low wind
speed, the reading of PM2.5 will fluctuate temporarily.
Note
：

SMART mode will change its setting according to the air quality and brightness of the surrounding
environment. Therefore, output flow rate will change time by time.

The output flow rate shown on the Air Volume Monitor will fluctuate according to the change of selected
mode.

To create a peaceful environment for sleeping, some indicators and the Air Volume Monitor will light off
when the SLEEP mode is selected.
