Frigidaire CRA156MT11 Filter
A changeable air filter was designed for filtering tiny dust fragments and other tiny particles as it passes through. This filtering system will help keep the wall unit from building up too much dust and help it be a lot better at doing its job while cleaning the air you breathe. During regular maintenance this filter should really be replaced or cleaned at least twice a year if not more, depending on how much you use it.
Clues to watch for to know the air filter will eventually need to be replaced
- If you were to lift up the filter, the light will barely break through to the other side of a completely clogged filter
- The air filter looks gray or brown and it would be best to replace it right away
- It is highly suggested to replace the filter about every three months to help clean the indoor air
