Frigidaire FAS155K1A3 Filter
The filter in the wall unit is designed to be good at trapping really small dust parts and other miniscule particles as it is being forced through the system. This filtering system will help keep the wall unit from building up too much dust and make it work much more efficient while also cleaning the air breathe in and out everyday. While doing regular cleaning of the houseZZZcommmaZZZ the filter should probably be changed out or cleaned a few times a year depending on how much you use it.
Some warnings of a failing dust filter
- It is highly suggested to switch out the air filter in your unit every three months for clean air inside the house
- When you face it toward a light, the light will hardly break through to the other side of a completely clogged filter
- The filter looks very bad and must be replaced right away
