Understanding Overall Air Quality

Overall air quality is categorized using 4 levels, ranging through green, yellow, orange and red
depending on the contamination levels of the air based on the concentration of dust.

Orange Unhealthy

Green Good
• The dust concentration can be determined by the color displayed by the air quality light.
• The color that appears in the air quality light is determined based on the condition of the worst dust
concentration level among dust concentration levels.
NOTE
• The level of dust concentration for LG Electronics products is the result expressed after measuring
the quantity of dust using an optical method and converting the measurement into fine dust
concentration.
• The dust concentration displayed on the product may be different from the measurement standards
of other instruments and other products.
• The dust concentration criteria for PM1.0 were set based on the same criteria as PM2.5. (Company
Standard)
• When using different or identical products in the same space, air circulation may cause differences
in the level of dust concentration.
• The flow around the dust sensor interferes with the normal operation of the dust sensor, so the
level of dust concentration displayed may differ from the actual level of dust concentration.
• If the product is used in the following environments, the level of dust concentration displayed may
differ from the actual value:
– Around fabric sofas and beds, around shaggy carpets, when arranging blankets/clothes, when
vacuum cleaners are in use, insects and pet areas, high humidity areas;
– Places where outside air enters, such as construction sites, roadsides, factories or around
entrances, windows and ventilation openings;
– Where there are products that generate steam and fine particles (humidifiers, cookware,
sprays, etc.);
– Even if dust is generated by activities such as mopping or cleaning, the sensor may not
respond if dust larger than fine dust is generated, but the dust will be removed by the filter.
