7. Replace a worn out HEPA fi lter (1) . To disman-
tle the fi lter, see point 1–4. Take the new HEPA
fi lter out of the plastic bag and insert it into the
air cleaner with the arrow pointing inward (see
picture).
8. After installing the pre- fi lter and the HEPA fi lter,
insert the top of the inlet grill (2) fi rst and then
snap in the lower part of the grill (2) .
NOTICE: It is recommended to wear gloves while discarding the used fi lter. Place
the used fi lter in a plastic bag to prevent dust from re-entering the air. It is impor-
tant to distinguish the front side from the back side of the fi lter. Change the HEPA
fi lter (1) when all the bars are lit. If the unit operates in an environment where the
air quality is low, replace the HEPA fi lter earlier, before all the bars are lit. We rec-
ommended checking the fi lter every 6 months. Never use a used fi lter in a reverse
direction, otherwise the dust absorbed will be blown out. A polluted HEPA fi lter
can not be cleaned, it can only be replaced.
