Frigidaire CRA073PU113 Filter
The unit filter is there for removing small dust molecules and other miniscule particles from the air in the house. The filter can both keep the unit clean and make it work much more efficient while also cleaning the air you breathe. Due to the fact that this is an important part of the system, the unit filter must be swapped out for a new one or cleaned a few times a year depending on how much you use it.
