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.
