In regard to the Air cleaning filters

(The air cleaning filter type differs depending on the model.)

[AIR-PURIFYING FILTER (green filter)]

●Depending on the size of the room and the conditions in which the air conditioner is used, the normal life of the air-purifying filter is about three months. If the air-purify- ing filter becomes dirty within three months, replace it as soon as possible. (Always dispose of used air-purifying filters, do not reuse them.)

[DEODORIZING FILTER (black filter)]

●To regenerate the deodorizing effect, remove the dust with a vacuum cleaner and place the filter in direct sunlight for six hours about once every six months. Under normal conditions, the filter should be replaced after three years.

●For storage of the air cleaning filters, avoid places with high temperatures and high humidity, and use the filters as soon as possible after the package has been opened. (The air cleaning effect decreases when the filters are left in the opened package.)

[POLYPHENOL CATECHIN AIR CLEANING FILTER (white filter)]

●The Air Cleaning Filters are disposable filters. (They can not be washed and reused.)

●For storage of the Air Cleaning Filters, use the filters as soon as possible after the package has been opened. (The air cleaning effect decreases when the filters are left in the opened package)

●Generally, the filters should be exchanged about every three months.

[NEGATIVE AIR IONS DEODORIZING FILTER (light green filter)]

●The filters should be exchanged about every three years so as to maintain the deodorizing effect.
