Checking before using the product
Information on the product
The product should not be used without the lter. When the lter smells bad, replace the lter with a new one.
The deodorization lter in the product is highly eective to remove not only domestic odor but also the formaldehyde,
VOCs, etc. which are the cause of sick house syndrome. Since the deodorizing function of the air purier becomes
eective as the air is circulated by the lter, ventilate the room at rst and then operate the deodorizing function if there
is strong odor. If you use the product in the suggested way, the performance of the air purier can be highly ecient.
If the air purier is used without a lter, air purifying function will not be carried out.
If the lter is dirty, purifying function works less eectively. If the exterior of the lter is dirty, the lter smells bad, or the
fan speed of the product observably decreases, the lter should be replaced.
When cooking food with a strong smell such as grilled sh, turn o the air purier.
If the air purier is used in a place where food with strong smell is made, the product life of the deodorization lter can
dramatically decrease. In the worst case, the smell from food pervades the deodorization lter and the lter generates
the food smell even after ventilation. Therefore, use the air purier to remove the remaining smell after carrying out
ventilation.
If the odor around the air purier pervades the HEPA or deodorization lter and generates the odor with the air purier
operation, the lters should be replaced.
When operating the air purier, close windows or doors.
If the air purier operates with the window or door opened, purifying function will work less eectively.
Carbon monoxide (CO) normally comes from outdoor area and it cannot be eliminated.
Main harmful gas that cannot be eliminated: Carbon monoxide (CO)
If the air purier is used in a closed area for long hours, concentration of carbon dioxide may increase. Therefore, carry
out ventilation regularly. If mild smell pervades the lter but it is used after ventilation several times, the smell of the lter
may decrease.
Using a lter
Before rst using the air purier, remove the vinyl packing of deodorization/HEPA lter (Integrated type).
- If an alarm rings or lter reset indicator blinks in the rst operation of the product, check the vinyl of the lter has been
removed.
If the air purier is used without a lter, air purifying function will not be carried out.
When the lter reset indicator ( ) is turned on, replace the old deodorization/HEPA lter (Integrated type) with new
ones. (The HEPA lter and deodorization lter eliminate particles of invisible ne dust and gas. Filter replacement period
can vary depending on the surrounding environment.)
If bad smell is generated, fan speed decreases, or replacement period passes, the deodorization/HEPA lter (Integrated
type) should be replaced.
If the dust lter is cleaned frequently, the eciency of the air purier increases.
For lter replacement procedure, refer to the 'Replacing the deodorization/HEPA lter' in the 'Cleaning and maintaining
the product' section.
Before replacing the lter, turn o the air purier.
