Checking Air Quality in the Display

The overall air quality is indicated by the color of the

icon in the display. If the overall air quality is unhealthy

(orange) or poor (red), the display also shows the cause.

In the example above, the PM1.0 (super ultra-ne dust) density

is shown as 58 micrograms per cubic meter, which is poor (red),

so it must be higher than the other PM densities. Odor also

appears in the display, so a strong odor is also detected.

Note

If the overall air quality is good (green) or moderate (yellow),

the cause is not displayed.

Checking Dust Density and

Humidity

While the product is on, press the Indicator button.

• Press the button repeatedly to quickly scroll through the

sensor results: PM10 → PM2.5 → PM1.0 → humidity.

• After the Indicator button is pressed, the status will

display for about 10 seconds.

Indicator

Note

• PM (particulate matter) density is displayed in increments

of 1 unit, from 8 to 999. PM density values are based on

the data sheet provided by the sensor manufacturer.

• The PM10 and PM2.5 air quality values follow those

provided by the United States EPA (Environmental

Protection Agency) for 2015.

– The overall air quality level displayed on the product

may differ from the level announced by the EPA.

• The PM1.0 density is displayed in the same manner as the

PM2.5 density and is based on LG Electronics standards.

• The PM10 and PM2.5 densities displayed by the product

could differ from the EPA forecast and from densities

measured by other products or devices.

– Differences in PM density values may be the result

of different methods of measuring or differences in

the actual PM density levels.

– The PM density measurement was tested using LG

Electronics' standard test materials.

• Using the product near a humidier, mister, air-conditioner,

or other device which generates steam or micro-particles

could affect the PM densities.

• The overall air quality level is a result of both PM densities

and the odor level. It may differ from the PM10, PM2.5,

and PM1.0 density levels.

• Even two products placed in the same space could

measure the PM10 density differently due to air circulation.

• The chemicals contained in air fresheners, perfumes,

deodorizers, or cosmetics may affect the overall air quality

display.

• The dust density displayed may change with environmental

factors such as the presence of sofas, beds, carpets,

vacuum cleaners, humidity, smoke, bugs, pets, or cooking

oils.

• The PM densities may be affected by changes in the

outside environment such as construction, heavy trafc, or

pollen.

• The micro dust density could be higher near outside doors,

windows, vents, or in areas where outside air enters.

• Use ONLY water to clean the sensor. Using anything else

could cause product failure.

• The ne dust density could be affected by cooking

or using humidiers, sprays, or other products which

generate steam or ne particles.
