Frigidaire FAX050S7AF Filter
The filter in the wall unit was designed for removing microscopic dust and other tiny particles as it is being forced through the system. This filtering system will help make the unit cleaner and make it run way more efficiently while also filtering the air you breathe. Due to the amount of dust in the house, the filter should probably be exchanged or cleaned a few times a year in order to keep things clean.
Clues of a poor dust filter
- The unit air filter looks gross and it would be a good idea to replace it as soon as you can
- It is greatly advised to replace the filter four times a year in order to have clean air running through the unit
- If you place a light source behind it, the light will almost not breach the other side of the dirt filled filter
