4 Operation

4.1 Understanding the Air Quality Light Ring

The light ring indicates the air quality. It lights up all colors in sequence when the air purifier is switched on. After approximately 30 seconds, the particle sensor selects the color that corresponds to the surrounding air quality of airborne particles, according to the table.

PM2.5

PM2.5 refers to ultra-fine airborne particle pollutants smaller than 2.5 micrometers. Most indoor air pollutants fall under PM2.5, such as tobacco smoke, cooking and burning candles, some airborne bacteria, the smallest mold spores, pet allergen, and dust mite allergen particles. The air quality sensor scans the air continuously to detect ultra-fine particles. This information is reported continuously on both the digital display and the light ring, providing real-time PM2.5 feedback.

4.2 Switching ON/OFF

• Insert the plug of the air purifier into the power socket.
• Touch the power button [4] to switch on the air purifier.
• Press the power button [4] again to switch off the air purifier.

Note

• For optimum purification performance, close the doors and windows.
• Keep curtains away from the air inlet or air outlet.
• The air purifier will operate in Auto mode by default.

4.3 Changing the Mode Setting

Auto Mode [9]

In Auto mode, the air quality is registered in real-time, and the appliance automatically adjusts the fan speed according to the ambient air quality.

Manual Mode [2]

5.2 Cleaning the Particle Sensor

Note:

• If the air purifier is used in a dusty environment, it may need to be cleaned more often.
• If the humidity level in the room is very high, condensation may develop on the particle sensor, and the air quality light may indicate poorer air quality even though the air quality is good. If this occurs, clean the particle sensor.

Clean the particle sensor every month for optimal functioning of the appliance.

• Switch off the air purifier and unplug from the power socket.
• Pull the back cover from the sensor and remove it from the appliance.
