[LG Air Conditioner Air Purification] I want to know how to clean the dust sensor

Repair

Would you like to know how to clean the sensor for clean use?

PM1.0 sensor can perform real time monitoring of ultra fine size dusts with the diameter of 1.0㎛ which is 1/100 of that of hair.
After the sensor detects the indoor density of dust, the display window of the stand or wall mounted air conditioner will display the results in 4 levels ranged from [Good] to [Very Bad].
If you use the air purification function when the indoor air is [Bad[ or [Very Bad], it will reduce the density of dusts in the indoor air.
If there are dusts in the PM1.0 sensor, then it cannot accurately detect the indoor air pollution, so make sure to clean it frequently.

Wait! Find out more.
