Tips for Using the Air Purifier
• When cooking food with heavy gaseous particles, such as frying fish, please try not to use the
air purifier if possible.
-- The oil vapor emitted from cooking may affect the performance and service life of the filter,
and it may also be stuck on the screen.
• When sleeping, please keep yourself at least 1 meter from the air purifier.

6. Place the air purifier on a stable, level
surface with a clear area around it for air to
Remove the plastic bag from the filter before use or the product will not be able to circulate air.
Air Purification
The air purifier cleans and refreshes indoor air.
1. Press the
Start/Stop button to turn on the air purifier.
• A chime sounds and the PM density display and the fan speed display turn on.
2. Press the
Speed button to select the desired fan speed.
• Press the button repeatedly to toggle through the settings: Auto → Low → Medium → High →
Turbo → Auto.
• The default mode is AUTO.
(The AUTO mode controls fan speed based on the air quality.)
• The sensor takes 30 seconds on initial startup to stabilize and prepare an air quality level
reading. After 30 seconds, the indoor air quality and PM density levels are displayed.
Indoor Air Quality Color Range
(Dirty) Violet → Pink → Red → Orange → Yellow → Green (Clean)
Press the
Light button to turn the air quality indicator light on/off.
PM Indicator Display
1. Press the
Indicator button to check the density of PM10/PM2.5/PM1.0.
• Pressing the button repeatedly toggles through to check the density of PM10 → PM2.5 →
PM1.0 in turn. The selected density displays for 10 seconds before the display reverts to the
highest measured PM (particulate matter) level.
2. Check the dust particle size LED indicators.
• PM density is displayed based on the dust density result with the highest contamination level.
For example, if PM10 density is 100 (Moderate), PM2.5 is 80 (Unhealthy), and PM1.0 is 30
(Good), the value for PM2.5 is displayed for PM density.
Understanding Overall Air Quality
Overall indoor air quality is displayed as one of six colors depending on the contamination
level of PM10, PM2.5, PM1.0, and odors.
(Dirty) Violet → Pink → Red → Orange → Yellow → Green (Clean)
• The color that the air quality indicator light displays is based on the worst level among PM10,
PM2.5, PM1.0, and odor.

PM density ranges from 8 to 999 in increments of 1. PM density values follow the data sheets
provided by the sensor supplier.
• Display description: If the density of PM1.0 is 120μm/m3, the air status is Poor (in red), and on
the air pollution source display will show dust. On the air pollution source
display will show odor, indicating that the odor concentration is high. On
the dust particle size display will show PM1.0, indicating that the density of
PM1.0 is greater than that of PM10 or PM2.5.
• The PM10 and PM2.5 air quality values are based on LG Electronics standards.
-- The overall air quality level displayed on the product may differ from the level announced by
the Central Pollution Control Board (CPCB).
• 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 Central Pollution
Control Board (CPCB) 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 humidifier, mist generator, air-conditioner or other devices 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 traffic 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 fine dust density could be affected by cooking or using humidifiers, sprays or other products
which generate steam or fine particles.
Using the Ionizer
It is used to produce negative ions and eliminate various bacteria in the indoor air.
1. Press the
Start/Stop button to turn on the Air purifier.
2. Press the
Mosquito Away button for 3 seconds.
