EN
Checking Air Quality
The overall air quality is indicated by the color of the air quality light and in the status display panel.
Overview of the Air Quality
The overall air quality is calculated based on the concentrations of odors and particulates in the air and is
categorized into 4 levels depending on these concentrations.
Color
Overall Air
Quality Concentration of PM (μg/m3) Concentration of Odor
State
PM10
(coarse
particles)
PM2.5
(fine particles)
PM1.0
(particles with
a diameter
between 1.0
and2.5μm)
State Level
Red Poor 255 or more 56 or more 56 or more Very strong 4
Orange Unhealthy 155 ~ 254 36 ~ 55 36 ~ 55 Strong 3
Yellow Moderate 55 ~ 154 13 ~ 35 13 ~ 35 Normal 2
Green Good 54 or less 12 or less 12 or less Weak 1
NOTE
• The color of the air quality light is based on the worst level detected, whether odors or particulates.
• PM (particulate matter) concentration is displayed in increments of 1 unit, from 8 to 999. PM
concentration values are based on the data sheet provided by the sensor manufacturer.
• The PM concentration measurement was tested using LG Electronics’ standard test materials.
• Differences in PM concentration values may be the result of different methods of measuring or
differences in the actual PM concentration levels.
−If the PM concentration is high, there may be a larger difference between the displayed concentration
and the actual concentration.

17
EN
Air Quality Details on the Status
Display Panel
aOverall Air Quality
The overall air quality is indicated by the
color of the icon at the top of the status
display panel.
bOdor Concentration
The odor concentration is indicated by the
color of the Odor icon on the status display
panel.
cPM Concentration
The particulate matter (PM) concentration
is indicated in the PM concentration display
and by the color of the PM size indicator.
The number that appears in the display is
the worst level detected among the PM10,
PM2.5, and PM1.0 sensors.
dPM Size
This display shows whichever PM size has
the highest concentration. The color of the
display indicates the PM concentration level
only.
Turning Air Quality Light On/Off
1 The overall indoor air quality is indicated by
the color of the air quality light.
a Air quality light
2 Press the Light button to turn it on/off.
NOTE
• When the appliance is turned on, the air
quality light is white during the initial sensor
stabilization period (30 seconds). The odor
sensor takes 2 minutes to stabilize after the
appliance is turned on.

18
EN
Checking Particulate Levels
To check the particulate matter concentration by
particulate size, press the Indicator button while
the appliance is operating.
• Press the button repeatedly to see the PM
levels displayed in the following order:
PM10 ~PM2.5 ~PM1.0
• The concentration for the selected particulate
size is displayed for about 10 seconds.
NOTE
• The overall air quality level is a result of both
PM concentration and the odor level.
• Even two products placed in the same space
could measure the concentration of particles
differently due to air circulation.
• Unlike the odor level, the PM concentration
may take time to measure accurately due to the
slow diffusion rate.
• Due to the flow around the particle sensor,
the displayed PM concentration and actual
concentration may differ.
• The PM concentration measured may differ
from the actual PM concentration in the
following cases.
−The presence of sofas, beds, carpets,
vacuums, humidity, smoke, fragrances,
cosmetics, perfumes, insects, or pets
−If the appliance is located near a construction
site, road, factory, doorway, window, or vent
−If the appliance is located near cooking,
humidifiers, sprays or other products which
generate steam or fine particles.
