WARNING
• Stop the appliance operation and unplug the
power cord before cleaning and replacing the
filter.
• Do not spray water directly on the appliance.
NOTE
• The color of the filter may vary depending on the
usage environment and color of dust.
• The cleaning frequency may vary depending on
the operating hours and environment of the
appliance.
• If you do not clean the product according to the
cleaning frequency, you may experience a bad
odor and poor performance.
• The filter must be replaced at the end of its
lifespan, and the cost of replacement filters is
not covered under the warranty. To purchase
new filters, contact an LG Electronics Customer
Information Center or visit the website at
www.lg.com
• The upper and lower parts of the filter are made
of paper instead of plastic. Repeated removal of
the filter may cause scratches on the top and
bottom of the filter.
• Scratches on the top and bottom of the filter will
not affect its performance.
Cleaning the Exterior
1 Remove dust from the air inlet and outlet
using a vacuum cleaner.
2 Wipe the exterior of the product with a soft
cloth.
CAUTION
• Do not wipe the appliance with an alkaline
detergent.
• Never use sulphuric acid, hydrochloric acid or
organic solvent (for example, thinner, kerosene
and acetone) to wipe the appliance exterior, or
affix labels on the exterior. Doing so may
damage the product surface.
• Care should be exercised to prevent water from
flowing into the product.
NOTE
• If it is difficult to remove dust from the front and
rear covers, disassemble the covers and clean
them with water. After cleaning, dry the covers
thoroughly in the shade.
• If fingerprints or dust on the front and back
covers are difficult to remove, wipe them off with
a microfiber cloth moistened with alcohol.
Cleaning the Particle Sensor
The PM1.0 (super ultra-fine dust) sensor detects
fine dust and large dust levels. For best results
clean the lens periodically, at least once every 2
months.
1 Facing the front of the product, hold and
gently pull both sides of the air inlet (cover) to
remove it.
• The side with the LG logo at the center of
the product is the front of the product.
2 Open the sensor cover.
