Frigidaire CRA050XT721 Filter
The air filter has the main responsibility for removing small dust molecules and other tiny bits as it passes through. This can both make the unit cleaner and make it run much more efficient while also filtering the air in your home. Because it is really easy to do, the air filter must be swapped out for a new one or perhaps washed at least twice a year if not more, in order to keep things clean.
Major signs of a declining main filter
- The filter looks very bad and probably should be replaced today
- It is recommended to replace the filter every 90 days to keep the house clean and less dusty
- Sunlight cannot shine on the opposite side of the air filter
