SMART AIR QUALITY SYSTEM
The air quality display senses and shows indoor particulate levels in real time. It can sense fine
particulate matter of 1.0 micron or smaller.
MULTI-STAGE FILTRATION SYSTEM
The combination of the washable pre-filter, 3M MERV 14 filter, and deodorizing filter provide
fresh indoor air by removing invisible air pollutants. Remove irritants ranging from pet hair and
pollen to tobacco smoke odors and VOCs.
LODECIBEL™ QUIET OPERATION
In the sleep mode, the air purifier runs at only 23 dB and can be scheduled to shut off
automatically, making falling asleep easy.
3M MERV 14 FILTER
The 3M MERV 14 filter captures 99.9% of particles as small as 0.3 microns. This particulate
matter can include pollen, mold spores, and dust.

Function
Pre-Filter
Filters out large particles to prolong the lifespan of the 3M MERV 14
filter.
3M MERV 14 Filter
Removes fine particles such as dead ticks, pollen, cigarette smoke
(particulates), micro dust motes, and animal fur, and performs strong
sterilization of the bacteria in the indoor air.
Deodorizing Filter
Comprehensively removes odors from cigarette smoke, garbage, pets,
strong acids or bases (vinegar, bleach).
h The life-expectancy of the filters depends on the usage environment of the air purifier.
h Do not discard the filter case. Replacement filters do not include a new case.
!
NOTE
• If requested from the LG Customer Information Center, the entire filter can be cleaned for
the actual cost of the cleaning.
• The effective life of the filters varies depending on the operational environment.
• The composition of filters can vary by model.
• Replacement filters can be purchased from a nearby LG service center or online through
LG.com.
• Use only the filters designed and approved by the manufacturer for use with this product.
INSTALLATION
Choosing the Proper Location
• Place within reach of a power outlet.
• Make sure air inlet and outlet are free from obstacles.
• Place on a level, stable surface where air circulates freely.
• Elevate air purifier on a stable table for more efficient operation.
! WARNING
This product is not designed for maritime use or for mobile installations such as in RVs,
trailers, or aircraft. Failure to follow this warning can result in product failure.
! WARNING
This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for
their safety.
Children should be supervised to ensure that they do not play with the appliance.
! WARNING
This appliance has a polarized plug (one blade is wider than the other). To prevent the risk of
electric shock, this plug is intended to fit in a polarized outlet only one way. If the plug does
not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician.
Do not attempt to defeat this safety feature.
Tips for Using the Air Purifier
• Avoid using the air purifier while cooking strong-smelling or fried foods such as fish.
- The vaporized oil from the cooking may affect the performance and life-expectancy of the
filters and the odors may cling to the filter.
• Do not place the air purifier closer than 3 1/4 ft (1 m) to the bed.
- The fan speed in sleep mode is low, but it could cause an unwanted draft.
• Do not place the air purifier in a corner.
- Avoid surrounding the appliance with furniture and electronic equipment or crowding it into a
corner. The air purifier works best when air is free to circulate around it.

OPERATION 13
ENGLISH
OPERATION
Air Purification
The air purifier cleans and refreshes indoor air.
1. Press the
button to turn on the air purifier.
• A chime sounds, the operation mode indicator LED lights up, and the air quality indicator light
turns 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
→ 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.

14 OPERATION
ENGLISH
Turbo Function
Use this function to set the air purifier at the highest setting for 30 minutes.
1. Press the
button.
2. Press the
Turbo button.
• The air purifier operates at the highest setting for 30 minutes and then returns to the
previous setting.
• If the Turbo function is selected while the air purifier is in the sleep mode, the PM density
display turns off after 3 seconds, the Turbo function operates for 30 minutes, and then the
product returns to the sleep mode.
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 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 (normal), PM2.5 is 50 (bad), and PM1.0 is 30 (normal),
the value for PM2.5 is displayed for PM density.
Air Quality Indicator Light
Overall indoor air quality is displayed as one of four colors depending on the contamination level
of PM10, PM2.5, PM1.0, and odors.
(contaminated) 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.

h PM density ranges from 8 to 999 in increments of 1. PM density values follow the data
sheets provided by the sensor supplier.
• In the example above, the PM1.0 density displays at 50 ug/m³ (a bad or orange level) and the dust particle
size LED indicator for PM1.0 is lit. This indicates that the PM1.0 level is higher than the PM10 or PM2.5
levels. If all the PM density levels are normal/good and the air quality indicator light is orange/red, the level
of odors is very high.
NOTE
• PM10 and PM2.5 density levels follow standards provided by the U.S. EPA (Environmental Protection
Agency).
- The overall air quality level displayed on the product may differ from the level announced by the EPA.
• The PM density level for PM1.0 is displayed in the same manner as the PM density level for PM2.5 (using
standards developed by LG Electronics).
• The displayed density of PM10 / PM2.5 could differ from the forecast of the EPA and from other
measurement devices or products.
- Indicated dust concentration values can differ from each other depending on the differences in dust
measuring methods and also from real dust concentration levels.
- The assessment of dust density was made against dust used for LG Electronics standards tests.
• The use of products which generate steam and micro particles (humidifiers, cooling devices, sprayers, etc.)
can change the micro dust density.
• Because the indoor air quality display shows the overall dust and odor level, it could differ from the density
value of PM10, PM2.5, and PM1.0
• Even in the same space, the PM10 density value could differ from other products due to air circulation.
• The displayed PM density value could change depending on the installation environment (including the
presence of sofas, beds, carpets, vacuum cleaners, humidity, smoke, bugs, oils, and other factors).
• The displayed density value of PM10/PM2.5/PM1.0 could change depending on the surrounding
environment (construction site, roadside, factory, etc.)
• The density of micro dust could be higher near exit doors, windows, and vents or anywhere where outside
air enters.
• Do not clean the sensor with anything but water. Doing so may cause product failure.
