Set the sensitivity of the
air quality sensor
People with certain health problems
(for example: allergies or asthma) have
a greater need for healthy air. For this
reason, the purifier allows you to adjust
the sensitivity of the air quality sensor. If
you set it to higher sensitivity level, the
purifier starts cleaning the air at lower
pollution level.
There are 3 sensitivity levels:
•
Extra sensitive (default setting)
•
Sensitive
•
Standard
You can adjust the sensitivity of the air
quality sensor in the following way.
Note
• When it is set to a higher sensitivity,
the purifier starts cleaning the air at
lower pollution levels to make the air
even cleaner. Plug the purifier before
adjusting the sensitivity of the air
quality sensor.
