The unit filter is good at removing small dust molecules and other tiny bits as it is being forced through the system. This filtering system will help keep the wall unit from building up too much dust and make it run way more efficiently while also cleaning the air breathe in and out everyday. Because of this, it should be changed out or perhaps cleaned thoroughly at least twice a year if not more, in order to keep things clean.
