Frigidaire FAC085J7A3 Filter
The filter in the wall unit is designed to be good at removing microscopic dust and other tiny bits as it is being forced through the system. The filter can both keep the unit clean and help it be a lot better at doing its job while also cleaning the dust out of the air you breathe all day. During regular maintenance the filter should probably be exchanged or perhaps cleaned thoroughly at least twice a year if not more, depending on how much you use it.
Subtle hints the dust filter is failing
- Many pros have suggested to replace your air filter four times a year to keep the unit running efficiently
- If you hold it up to the light, it will almost not permeate to the other side of the filter at all
- The unit air filter looks bad and should be replaced right away
