The air filter is the best line of defense when removing microscopic dust and other tiny particles as it passes through. This filtering system will help keep the wall unit from building up too much dust and make it work a lot better at doing its job while also filtering the air you breathe in your house. Due to the fact that this is an important part of the system, the filter should be swapped out for a new one or possible scrubbed clean every so often depending on how much you use it.
