Frigidaire FAC109S1AA Filter
A changeable air filter has a main job of filtering tiny dust fragments and other unwanted bits as it passes through. This simple filter can keep the unit dust-free and make it work more efficient while also cleaning the dust out of the air you breathe all day. Because of this, the air filter must be changed out or simply cleaned a few times a year in order to keep things clean.
Major clues the primary air filter will need to be replaced
- If you lift the air filter up to a source of bright light, the light will not penetrate through a very dirty air filter
- Manufacturers have advised to swap out your air filter four times a year so as to have cleaner breathable air
- The filter looks brown and it would be a good idea to replace it as soon as you can
