Frigidaire FAX051P7A5 Filter
The filter in the wall unit was created for filtering tiny dust fragments and other tiny particles as it is being forced through the system. This can both make the unit cleaner and make it run way more efficiently while also filtering the air in your home. Because of the nature of filtering air, the filter should probably be replaced or cleaned every so often in order to keep things clean.
Key clues of a deteriorating main filter
- With a light behind the air filter, the light will barely break through to the other side of the filter at all
- The system filter looks bad and should be replaced real soon
- Manufacturers have suggested to replace the filter every season of the year to help keep the air fresh and make the unit run more efficient
