Please read before operating your new Air Purifier
The air purifier draws in room air from its air intake, lets the air pass through a
Active Carbon Filter (deodorization filter) and a HEPA Filter (dust collection
filter) inside of the unit, then discharges the air from its air outlet. The air
purifier unit repeats this process by moving its internal fan.
As air passes through, a new HEPA Filter can remove 99.97% of dust parti-
cles, of as small as 0.3 microns. The Active Carbon Filter gradually absorbs
odour elements as they repeatedly pass through the filter. (Odour elements
are absorbed by HEPA Filter as well.)
Some odour ingredients absorbed by the filters may become separated and
may be discharged through the air outlet and result in additional odour. De-
pending on the usage environment, especially when the product is used in a
condition significantly more severe than household use, this odour may be-
come strong in a shorter period than expected.
If the odour persists, then the filters are fully expended and it is necessary to
purchase the optional replacement filter.
NOTE
• The air purifier is designed to remove air-suspended dust and odour, but not harmful gases (for
example, carbon monoxide contained in cigarette smoke). If the odour sources still exist, it cannot
completely remove the odour. (for example, odours from construction materials and pet odours).
• It is suggested to open the window a bit when you are smoking in order to facilitate ventilation.

Preparing the descaling
solution.
Citric acid, available at some drugstores, or
100% bottled lemon juice are used for
descaling. Choose either one to use, and
prepare the descaling solution.
<For using citric acid>
Dissolve 3 teaspoons of citric acid and 600 ml of
luke-warm water in a suitable container, and stir well.
<For using lemon juice>
Use only bottled 100% lemon juice with no pulp
(please check before using and strain through a fine
strainer there seems to be some pulp). Pour 50 ml
of lemon juice and 600 ml of luke-warm water in a
suitable container, and stir well.

Presoak the mist filter in the
solution prior to cleaning.
When using lemon juice,
it is recommended to
presoak longer than
citric acid.
Rinse the MIST Filter with
water.
• Change the water and
repeat this procedure 2-
3 times.
• Use clean water each
