Frigidaire FAM18ER2A12 Filter
The filter has a main job of filtering tiny dust fragments and other tiny bits as it passes through. This can both keep the unit dust-free and make it operate a lot better at doing its job while, at the same time, filtering the dust out of the air you breathe all day. Because of this, the filter should probably be replaced or simply cleaned periodically depending on how much you use it.
Major symptoms of a deteriorating primary air filter
- Professionals have recommended to swap out your air filter every three months to help keep the air fresh and make the unit run more efficient
- When you hold the filter up to the light, it does not break through to the other side of a very dirty air filter
- It looks brown and it would be best to replace it right away
