The filter was designed for trapping really small dust parts and other particles from the air in the house. This simple filter can protect the unit and make it work more efficient while also cleaning the air you breathe in your house. Due to the fact that this is an important part of the system, this filter should really be replaced or possible scrubbed clean every so often in order to keep things clean.
