Frigidaire CRA050XT722 Filter
The filter in the wall unit was created for trapping really small dust parts and other particles from the air in the house. This helps protect the unit and make it work more efficient while, at the same time, filtering the air you breathe. Because it is really easy to do, the filter should probably be exchanged or perhaps washed periodically in order to keep things clean.
Symptoms your filter has to be replaced
- Sunlight will not show through a very dirty air filter
- The system filter looks brown and should be replaced before tomorrow
- It is highly suggested to replace your air filter every 90 days to help prevent bacteria from spreading too much
