Make sure that the doors  
and windows are shut tight.  
Clean the air filter  
regularly.  
Ventilate the room  
occasionally.  
Avoid opening doors and  
windows as much as possible to  
keep the cool air in the room.  
Blockages in the air filter reduce  
the airflow and lower cooling and  
dehumidifying effects. Clean at  
least once every two weeks.  
Since windows are kept closed,  
it is a good idea to open them  
and ventilate the room now and  
then.
