Frigidaire FAX054P7A15 Filter
The filter in the wall unit has a main job of filtering minute dust particles and other unwanted bits as it is being forced through the system. This helps protect the unit and make it run more efficient while also cleaning the air breathe in and out everyday. During regular maintenance it should be simply replaced or simply cleaned every so often depending on how much you use it.
Important signs your filter will need replacing
- Professionals have suggested to replace the filter about every 90 days so as to have cleaner breathable air
- The system filter looks bad and replacing it would be best without delay
- If you place a light source behind it, the light cannot shine through the filter at all
