Frigidaire FAC127S1A14 Filter
The unit filter is there for filtering tiny dust fragments and other tiny particles as it passes through. This simple filter can help keep the wall unit from building up too much dust 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 be changed out or perhaps washed a few times a year depending on how much you use it.
Subtle hints your main filter has to be replaced
- It is highly recommended to switch out the air filter in your unit every three months to help prevent mold and bacteria build-up
- When you hold it up, the light does not infiltrate to the opposite side of a completely clogged filter
- The system filter looks gross and it would be a good idea to replace it right now
