l This is not a problem as long as there is no abnormal noise or abnormal vibration.

<How to check monitor operation>
l Rub tissue paper near the PM2.5 Sensor so as to create dust.
l Place perfume, hair tonic, or the like on tissue paper and then place the tissue paper in front of the main
unit so that the fragrance is sucked into it.
l Is there dust on the PM2.5 Sensor and odor sensor?
→ Clean the PM2.5 Sensor and odor sensor.
l Response will be slow for a few minutes after the operation On/Off switch is
turned ON because the PM2.5 Sensor and odor sensor are performing the
preparation operation.
l The monitor indication may not change sometimes because the sensitivity of the
sensor differs depending on the components of the odor.
l The monitor may sometimes respond to the wind from an air conditioner in the
room or gas that is difficult for a human nose to sense.
l Is there dust floating in the air? If there is even a small amount of dust floating in
the air, the monitor may respond.
l Adjust the sensitivity of the PM2.5 Sensor and wait and see.
l It is time to replace the HEPA filter and activated charcoal filter.
→ Replace the HEPA filter and activated charcoal filter.
l It is time to clean the dust box.
→ Clean the dust box.
l Is the dust box attached properly?
→ Attach the dust box properly.
l Are the pre-filter unit and dust box unit securely attached?
→ Attach the pre-filter unit and dust box unit properly.
l The cleaning mechanism is a function for removing dust on the pre-filter.
Cigarette tar and minute dust particles will not be removed.
