How to Clean the Air Filter
The filter prevents dust and other particles from entering
the indoor unit. Dust buildup can reduce the efficiency of
the air conditioner. For optimum efficiency, clean the air
filter every two weeks or more frequently if you live in a
dusty area. Replace the filter with a new one if it’s heavily
clogged and cannot be cleaned.
