NOTE
•A slight odor may be emitted from the new lter at the beginning after purchase. The
odor will disappear after a day or so of using the product, so you can use it without
worry.
•The frequency of cleaning and lter replacement may vary depending on environment
and usage time.
•Filters may be used for up to 1 year. The more polluted the indoor air, the shorter the
life of the lter.
•If an excessive odor is present in the room, rst ventilate the air to remove the odor,
and then use the air purier to remove the remaining odor.
•If the air purier is used after not having been used for a long time and there is an
odor, you can reduce the odor from the lter by operating it on fan speed 10 step in a
ventilated area
•The lter may emit an odor when used continuously in a humid environment or where
moisture from a humidier is absorbed into the lter. If odor is generated due to
moisture, dry the lter in sunlight before use.
•Carbon monoxide (CO) is a harmful gas that is mainly introduced from the outside,
and cannot be removed with a lter.
•Keep the windows or doors closed while using the product. However, if you operate
the product for a long time in a closed space, the carbon dioxide concentration may
rise. So be sure to ventilate the indoor regularly.
•The deodorization function of the air purier operates by trapping the odor in the lter.
If you use the product for a long time in a room with excessive odor, the performance
of the lter may decrease signicantly.
