The filter in the wall unit is designed to be good at filtering out dust and other tiny bits from the air in the house. This helps help keep the wall unit from building up too much dust and make it operate more efficient while also cleaning the air in your home. During regular maintenance this filter should really be changed out or cleaned a few times a year depending on how much you use it.
