Frigidaire FAC109S1AB Filter
The filter is the best line of defense when filtering minute dust particles and other particles as it passes through. The filter can both make the unit cleaner and make it run more efficient while also cleaning the air you breathe. Because of the nature of filtering air, the unit filter must be replaced or perhaps cleaned thoroughly at least twice a year if not more, depending on how much you use it.
Warnings of an inadequate main filter
- It is greatly advised to swap out your air filter about every 90 days so as to have cleaner breathable air
- When you face it toward a light, the light will barely penetrate through a very dirty air filter
- The main filter looks dirty and replacing it would be best soon
