Frigidaire FAH12ES2TA12 Filter
The filter in the wall unit is there for filtering minute dust particles and other tiny particles as it passes through. This filtering system will help keep the unit clean and help it be more efficient while also filtering the dust out of the air you breathe all day. Due to the fact that this is an important part of the system, the unit filter must be changed out or simply cleaned a few times a year depending on how much you use it.
Major symptoms your main filter is in need of replacing
- The system filter looks dirty and it would be a good idea to replace it now
- Light cannot breach the other side of a dirty filter
- It is greatly suggested to switch out the air filter in your unit every 90 days to help prevent bacteria from spreading too much
