Checking Air Quality
The overall air quality is indicated by color in the status
display panel and the air quality indicator light.
Understanding Overall Air Quality
The overall air quality is indicated using four levels, each
using a different color. The overall air quality depends on
both the dust density and the odor level.

• Overall air quality is indicated by the color of the icon
in the status display panel and of the air quality
indicator light.
• The overall air quality color indicates the worst level,
either the dust density or the odor level.
Using the Air Quality Indicator Light
The overall air quality light changes color to green (good),
yellow (normal), orange (bad) or red (very bad) depending on
the dust density and odor level.
Air quality
indicator light
Note
After initial startup, the dust sensor stabilizes for 30 seconds and
the odor sensor stabilizes for two minutes. The air quality light is
white for 30 seconds, then it changes color to indicate the dust
density level. Two minutes after starting, the light may change
again if the odor level is worse than the dust density level.
Turning Air Quality Indicator Light
On/Off
While the product is operating, press the Light button to
turn the overall air quality light on or off.
Light Light
Note
• The air quality indicator light turns off when the Off Timer
is set.
• If the Light button is pressed after the Off Timer is set,
both the air quality indicator light and the display indicator
light are activated.
19
ENGLISH
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 bad (orange) or
very bad (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 very bad
(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 normal (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 humidier, 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 trafc, 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 humidiers, sprays, or other products which
generate steam or ne particles.

PROCEDURE FOR RESOLVING DISPUTES:
ALL DISPUTES BETWEEN YOU AND LG ARISING OUT OF OR RELATING IN ANY WAY TO THIS LIMITED WARRANTY
OR THE PRODUCT SHALL BE RESOLVED EXCLUSIVELY THROUGH BINDING ARBITRATION, AND NOT IN A COURT
OF GENERAL JURISDICTION. BINDING ARBITRATION MEANS THAT YOU AND LG ARE EACH WAIVING THE RIGHT
TO A JURY TRIAL AND TO BRING OR PARTICIPATE IN A CLASS ACTION.
Denitions. For the purposes of this section, references to “LG” mean LG Electronics U.S.A., Inc., its parents, subsidiaries
and afliates, and each of their ofcers, directors, employees, agents, beneciaries, predecessors in interest, successors,
assigns and suppliers; references to “dispute” or “claim” shall include any dispute, claim or controversy of any kind
whatsoever (whether based in contract, tort, statute, regulation, ordinance, fraud, misrepresentation or any other legal or
equitable theory) arising out of or relating in any way to the sale, condition or performance of the product or this Limited
Warranty.
Notice of Dispute. In the event you intend to commence an arbitration proceeding, you must rst notify LG in writing at least
30 days in advance of initiating the arbitration by sending a letter to LG at LG Electronics, USA, Inc. Attn: Legal Department-
Arbitration 1000 Sylvan Ave, Englewood Cliffs 07632. You and LG agree to engage in good faith discussions in an attempt to
amicably resolve your claim. The notice must provide your name, address, and telephone number; identify the product that is
the subject of the claim; and describe the nature of the claim and the relief being sought. If you and LG are unable to resolve
the dispute within 30 days, either party may proceed to le a claim for arbitration.
Agreement to Binding Arbitration and Class Action Waiver. Upon failure to resolve the dispute during the 30 day
period after sending written notice to LG, you and LG agree to resolve any claims between us only by binding arbitration
on an individual basis, unless you opt out as provided below. Any dispute between you and LG shall not be combined or
consolidated with a dispute involving any other person’s or entity’s product or claim. More specically, without limitation of the
foregoing, any dispute between you and LG shall not under any circumstances proceed as part of a class or representative
action. Instead of arbitration, either party may bring an individual action in small claims court, but that small claims court
action may not be brought on a class or representative basis.
Arbitration Rules and Procedures. To begin arbitration of a claim, either you or LG must make a written demand for
arbitration. The arbitration will be administered by the American Arbitration Association (“AAA”) and will be conducted before
a single arbitrator under the AAA’s Consumer Arbitration Rules that are in effect at the time the arbitration is initiated (referred
to as the “AAA Rules”) and under the procedures set forth in this section. The AAA Rules are available online at www.adr.org/
consumer. Send a copy of your written demand for arbitration, as well as a copy of this provision, to the AAA in the manner
described in the AAA Rules. You must also send a copy of your written demand to LG at LG Electronics, USA, Inc. Attn: Legal
Department- Arbitration 1000 Sylvan Avenue Englewood Cliffs, NJ 07632. If there is a conict between the AAA Rules and
the rules set forth in this section, the rules set forth in this section will govern. This arbitration provision is governed by the
Federal Arbitration Act. Judgment may be entered on the arbitrator’s award in any court of competent jurisdiction. All issues
are for the arbitrator to decide, except that issues relating to the scope and enforceability of the arbitration provision and to
the arbitrability of the dispute are for the court to decide. The arbitrator is bound by the terms of this provision.
Governing Law. The law of the state of your residence shall govern this Limited Warranty and any disputes between us
except to the extent that such law is preempted by or inconsistent with applicable federal law.

ENGLISH
Fees/Costs. You do not need to pay any fee to begin an arbitration. Upon receipt of your written demand for arbitration,
LG will promptly pay all arbitration ling fees to the AAA unless you seek more than $25,000 in damages, in which case the
payment of these fees will be governed by the AAA Rules. Except as otherwise provided for herein, LG will pay all AAA ling,
administration and arbitrator fees for any arbitration initiated in accordance with the AAA Rules and this arbitration provision.
If you prevail in the arbitration, LG will pay your attorneys’ fees and expenses as long as they are reasonable, by considering
factors including, but not limited to, the purchase amount and claim amount. Notwithstanding the foregoing, if applicable law
allows for an award of reasonable attorneys’ fees and expenses, an arbitrator can award them to the same extent that a court
would. If the arbitrator nds either the substance of your claim or the relief sought in the demand is frivolous or brought for an
improper purpose (as measured by the standards set forth in Federal Rule of Civil Procedure 11(b)), then the payment of all
arbitration fees will be governed by the AAA Rules. In such a situation, you agree to reimburse LG for all monies previously
disbursed by it that are otherwise your obligation to pay under the AAA Rules. Except as otherwise provided for, LG waives
any rights it may have to seek attorneys’ fees and expenses from you if LG prevails in the arbitration.
Hearings and Location. If your claim is for $25,000 or less, you may choose to have the arbitration conducted solely on
the basis of (1) documents submitted to the arbitrator, (2) through a telephonic hearing, or (3) by an in-person hearing as
established by the AAA Rules. If your claim exceeds $25,000, the right to a hearing will be determined by the AAA Rules. Any
in-person arbitration hearings will be held at a location within the federal judicial district in which you reside unless we both
agree to another location or we agree to a telephonic arbitration.
Opt Out. You may opt out of this dispute resolution procedure. If you opt out, neither you nor LG can require the other to
participate in an arbitration proceeding. To opt out, you must send notice to LG no later than 30 calendar days from the date
of the rst consumer purchaser’s purchase of the product by either: (i) sending an e-mail to [email protected], with the subject
line: “Arbitration Opt Out” or (ii) calling 1-800-980-2973. You must include in the opt out e-mail or provide by telephone: (a)
your name and address; (b) the date on which the product was purchased; (c) the product model name or model number;
and (d) the serial number (the serial number can be found (i) on the product; or (ii) online by accessing https://www.lg.com/
us/support/repair-service/schedule-repair-continued and clicking on “Find My Model & Serial Number”).
You may only opt out of the dispute resolution procedure in the manner described above (that is, by e-mail or telephone);
no other form of notice will be effective to opt out of this dispute resolution procedure. Opting out of this dispute resolution
procedure will not affect the coverage of the Limited Warranty in any way, and you will continue to enjoy the full benets of
the Limited Warranty. If you keep this product and do not opt out, then you accept all terms and conditions of the arbitration
provision described above.
