• Set the fan speed to Auto. The fan speed does not change
automatically when it is set to Low , Medium, or High or when
the Wind-Free or Sleep mode is running.

• This may happen when the room is properly sealed and the air
is clean.

the sensor and/or rub them to create some dust. This will cause
the PM levels to change if the sensor is working properly.

sensor feedback if the dust particles are bigger than PM10,
while they are still filtered and removed from the air.
