Knowing the Air Quality
You can check the overall air quality by looking at the light of air quality and the status display panel.
Overview of the Air Quality
The overall air quality is calculated based on the particles and odour (gas) concentrations and is
categorized into 4 levels depending on the contamination of the air.

NOTE
• The colour of overall air quality is determined based on whichever is worse between the particles
concentration and odour (gas) concentration.
• 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, the difference between the displayed concentration and the actual
concentration may become large.

d
Particulate Matter
The colour of the particulate matter is
solely determined based on the particles
concentration.
NOTE
• The light of air quality turns on white for the
sensor stabilization period (30 seconds). The
odour (gas) sensor is stabilized 2 minutes after
you start the operation.

Knowing the Particles
Concentration
You can check the particulate matter concentration
by its particle size.
Press the Indicator button during the operation
• Whenever you press the button, the display
changes in the following order:
PM10 ~ PM2.5 ~ PM1.0
• The concentration of the selected particles is
displayed for about 10 seconds.
NOTE
• The overall air quality level is a result of both
PM concentration and the odour level.
• Even two products placed in the same space
could measure the concentration of particles
differently due to air circulation.
• Unlike the odour(gas), the concentration of
particles could be measured slowly due to the
slow diffusion rate.
• Due to the flow around the particle sensor,
the displayed PM concentration and actual
concentration may differ.
• When using the appliance in the following
environment, the PM concentration may be
displayed differently from the actual.
−− Where there are influences such as sofa,
bed, carpet, cleaner, humidity, smoke,
fragrance, cosmetics, perfume, insect, pet
−− Where there are construction site, roadside,
factory, entrance, window, ventilation
−− Where there are affected by cooking or using
humidifiers, sprays or other products which
generate steam or fine particles.
