●

Normal life of AIR CLEANING FILTER is 4 months. However, when it becomes dirty, replace it as soon as possible.

●

Clogged AIR CLEANING FILTER may reduce the air conditioner capacity or cause frost on the air outlet.

●

●

DEODORIZING FILTER removes ammonia and hydrogen sulphide emitted from tobacco, and odor of pets.

●

Clean DEODORIZING FILTER every two weeks. If the filter is particularly dirty, clean the filter more often.

●

For cleaning, soak the filter in warm water for a while, and then wash and rinse it. Dry the filter in the shade thoroughly.

●

When the filter color is still dark even after cleaning, replace the filter with a new one.

Replace the filter at least once a year.

●
