22 OPERATION
• Dust concentration may continuously change
according to the change of the indoor
environment.
• Overall cleanliness color is displayed based on
the highest contamination level among fine
dust(PM10), ultra fine dust(PM2.5), and super
ultra fine dust(PM1.0).
• The dust concentration and level displayed on
the product may differ from other measuring
instruments or other products.
• The dust concentration evaluation is carried out
with our company’s standard test dust.

• Guide to dust particles' size
- Fine dust (PM10): Dust with particle size of 10
μm or less (Generated from workplace
combustion, vehicle exhaust, etc.)
- Ultra fine dust (PM2.5): Dust with particle size
of 2.5 μm or less (Composed of ion
component, carbon compound, and metal
compound)
- Super ultra fine dust (PM1.0): Dust with
particle size of 1.0 μm or less (Cigarette smoke,
etc.)
• Fine / Ultra fine / Super ultra fine dust
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
fine dust, ultra fine dust, or super ultra fine dust
concentration value.
• Fine dust / ultra fine dust 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 fine dust, ultra fine dust, and
super ultra fine dust 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 color 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.
