Frigidaire CRA052XT71 Filter
The filter in the wall unit has the main responsibility for filtering out dust and other particles as it is being forced through the system. This can both keep the unit clean and make it run much more efficient while also filtering the air you breathe in your house. Due to the fact that this is an important part of the system, the unit filter must be replaced or possible scrubbed clean a few times a year in order to keep things clean.
What symptoms are present when the main filter is not working right?
- The filter looks dusty and must be replaced soon
- If you were to lift up the filter, the light cannot permeate to the other side of a completely clogged filter
- It is highly suggested to swap out your air filter about every three months in order to have clean air running through the unit
