Checking Air Quality
The overall air quality is indicated by the color of the air quality light and in the status display panel.
Overview of the Air Quality
The overall air quality is calculated based on the concentrations of odors and particulates in the air and is
categorized into 4 levels depending on these concentrations.
Colour
Overall Air

)
Concentration of
Odour
State
PM10
(coarse

Red Very Bad 255 or more 56 or more 56 or more Very strong 4
Orange Bad 155 ~ 254 36 ~ 55 36 ~ 55 Strong 3
Yellow Normal 55 ~ 154 13 ~ 35 13 ~ 35 Normal 2
Green Good 54 or less 12 or less 12 or less Weak 1
NOTE
• The color of the air quality light is based on the worst level detected, whether odors or particulates.
• PM (particulate matter) concentration is displayed in increments of 1 unit, from 8 to 999. PM
concentration values are based on the data sheet provided by the sensor manufacturer.
• The PM concentration measurement was tested using LG Electronics’ standard test materials.
• Differences in PM concentration values may be the result of different methods of measuring or
differences in the actual PM concentration levels.
− If the PM concentration is high, there may be a larger difference between the displayed concentration
and the actual concentration.

EN
Air Quality Details on the Status
Display Panel
a
Overall Air Quality
The overall air quality is indicated by the
color of the icon at the top of the status
display panel.
b
Odor Concentration
The odor concentration is indicated by the
color of the Odor icon on the status display
panel.
c
PM Concentration
The particulate matter (PM) concentration
is indicated in the PM concentration
display and by the color of the PM size
indicator. The number that appears in the
display is the worst level detected among
the PM10, PM2.5, and PM1.0 sensors.
d
PM Size

PM concentration and the odor level.
• Even two products placed in the same space
could measure the concentration of particulates
differently due to air circulation.
• Unlike the odor level, the PM concentration
may take time to measure accurately due to the
slow diffusion rate.
• Due to the flow around the particulate sensor,
the displayed PM concentration and actual
concentration may differ.
• The PM concentration measured may differ
from the actual PM concentration in the
following cases.
− The presence of sofas, beds, carpets,
vacuums, humidity, smoke, fragrances,
cosmetics, perfumes, insects, or pets
− If the appliance is located near a construction
site, road, factory, doorway, window, or vent
− If the appliance is located near cooking,
humidifiers, sprays or other products which
generate steam or fine particles.

The appliance does not
operate.
The power plug in unplugged from the outlet.
• Plug it into the outlet properly.
There is odor, but the
air quality light doesn’t
change
Is the air quality light red or orange?
• The color of the overall air quality light is determined by the worst level
sensed, whether that is a PM concentration or odor. The PM concentration
level may be worse than the odor level.
• The odor (gas) sensor is designed to detect harmful gases. Strong food
odors may not register as harmful, but the Deodorizing Care filter will
minimize them.
The air quality light
stays red.
Move the appliance to a different room and see if the color changes.
• If the odor level is beyond the capacity of the product to dispel, the light
may not change.
• Clean the sensor area.
• Remove the power plug from the outlet and reconnect it one minute later.

not match the PM
concentration value.
The overall air quality light may be reflecting the odor level.
• The overall air quality is based on both the PM concentration and the odor
level, and its color is determined by which is worse.
• If the PM concentration is low and the odor level is high, the overall air
quality light will reflect the odor level.
The clean booster is
not working.
The Booster mode is not selected.
• The booster fan speed and booster fan rotation functions work only in the
Booster mode.

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.
Definitions. For the purposes of this section, references to “LG” mean LG Electronics U.S.A., Inc., its
parents, subsidiaries and affiliates, and each of their officers, directors, employees, agents, beneficiaries,
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 first 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 111 Sylvan Avenue, Englewood Cliffs, NJ 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 file 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
35
EN
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 specifically, 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 111 Sylvan Avenue, Englewood Cliffs, NJ 07632. If there is a conflict 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.
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 filing 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 filing, 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 finds 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 first 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 benefits 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.
