Adjust Air Quality Sensor

When the product is shipped out, the air quality sensor is set to standard sensitivity. If the pollution level stays at the highest level after 2 hours of operation or stays at the lowest level for more than 1 hour when the air does not seem clean, users can adjust the sensitivity of the air quality sensor as follows.

1. While the air purifier is on, press the airflow speed button and ionizer button for 2 seconds.
2. The speed indicator will flash at 1.0 second intervals with beep. The speed indicator blinks to show the sensor sensitivity.
3. Adjust the sensitivity by pressing the speed button. The speed indicator blinks to show the sensor sensitivity.

   Speed step 1	Speed step 2	Speed step 3
   Sensitive	Standard	Insensitive

   * High sensitivity: If the air purifier indicates a pollution level of 1 for longer than one hour when the actual pollution level is higher.

   * Low sensitivity: If the air purifier continues to indicate the highest pollution level even after running the air purifier for more than two hours.

4. Press the airflow speed button and ionizer button for 2 seconds. The air purifier will then resume normal operations. * The new setting will also be applied if no button is input for 10 seconds.

Cleaning Method

Tips:

• Always unplug the air purifier before cleaning the product.
• Do not use detergents that contain organic solvents (solvent, thinner, etc), bleach, chlorine, or abrasives.
• Do not put the air purifier in water or spray water directly on it.

Cleaning the air quality sensor (every 2 months)
