Checking Overall Cleanliness

It displays the indoor cleanliness.

• Turn the appliance on.

• During the operation, if you press PM Sensor button, you can check the indoor cleanliness in each level.

  

Indoor Unit Icon	Description
	Overall cleanliness colour display
	Dust size dust concentration display

• Dust concentration is displayed in unit of 1 within 8~999 μg/m³. Dust concentration referred to the data sheet of the sensor manufacturer.

• Dust concentration may continuously change according to the change of the indoor environment.

• Overall cleanliness colour is displayed based on the highest contamination level among PM10(fine dust), PM2.5(ultra fine dust), and PM1.0(super ultra fine dust).

• Overall cleanliness colour is displayed in 6 levels according to the indoor contamination level.

• If dust concentration is high, the difference between the displayed dust concentration and the actual dust concentration may become bigger.

• Guide to dust particles' size

  • PM10(Fine dust): Dust with particle size of 10 μm or less (Generated from workplace combustion, vehicle exhaust, etc.)

  • PM2.5(Ultra fine dust): Dust with particle size of 2.5 μm or less (Composed of ion component, carbon compound, and metal compound)

  • PM1.0(Super ultra fine dust): Dust with particle size of 1.0 μm or less (Cigarette smoke, etc.)

• PM10 / PM2.5 / PM1.0 concentration may be different according to the surrounding environment. (Construction site, road side, factory, etc.)

• Dust concentration may be different according to the installation environment. It is influenced by couches, beds, carpets, cleaners, humidity, smoke, insects, pets, etc.

• In the environment with external air inflow such as near the door, window, or ventilation gate, etc., dust concentration may be measured as high.

• Even in the same space, due to the air circulation, dust concentration may be displayed differently from other products.

• Cleanliness display displays the fine dust comprehensively, so it may be different from PM10, PM2.5, or PM1.0 concentration value.

• PM10 / PM2.5 concentration displayed on the product may be different from Ministry of Environment announcement, and it may be different from other measurement devices or other products’ measurement standards.

• The displayed PM10, PM2.5, and PM1.0 concentration value may be different from Ministry of Environment forecast.

• If products generating steam or fine particles (humidifiers, cooking apparatus, sprays, etc.) are used, fine dust concentration may change.

• You can check cleanliness only when the air conditioner is in operation state.

• Dust concentration display value may be different from the actual dust concentration, and it may display different cleanliness colour from the actual dust concentration level.

• Dust concentration and overall cleanliness level displayed on the product may be different from Ministry of Environment announcements.

• Ministry of Environment uses weight method or beta ray absorption method to measure the dust concentration, but LG product measures the number of dusts and converts to mass concentration, so it may be different from the actual dust concentration.

• The same standard as PM2.5 is applied to PM1.0 concentration level. (LG standard)

• Dust concentration evaluation is carried out with LG standard test dust.

• The shaking around the dust sensor may hinder the normal operation of the dust sensor, and the displayed concentration may be different from the actual dust concentration.

• You can use it only in overall cleanliness function applied models.

• PM Sensor button in the remote controller can make to check each dust particle’s size dust concentration for 10 seconds.

  • After 10 seconds, the display is displayed the worst dust concentration among PM10, PM2.5, PM1.0 particle’s size.
