Frigidaire FAC084J7A2 Filter
The filter in the wall unit has the main responsibility for trapping really small dust parts and other miniscule particles as it passes through. This can both keep the unit dust-free and help it be much more efficient while cleaning the air breathe in and out everyday. Due to the amount of dust in the house, the filter should be swapped out for a new one or simply cleaned periodically depending on how much you use it.
Symptoms your main filter has very little life left
- Many pros have suggested to replace the filter four times a year to keep the unit running efficiently
- Sunlight will not permeate to the other side of the filter
- The system air filter looks gray or brown and could be replaced immediately
