Frigidaire FAA074S7A13 Filter
The filter in the wall unit is there for removing microscopic dust and other tiny particles from the inside air inside the home. This filtering system will help make the unit cleaner and make it run way more efficiently while, at the same time, filtering the air breathe in and out everyday. Because of this, this filter should really be replaced or possible scrubbed clean a few times a year in order to keep things clean.
What are the indications that my filter is not well?
- Many pros have suggested to replace the filter every season of the year for clean air inside the house
- If you lift the air filter up to a source of bright light, the light will barely break through to the other side of the dirt filled filter
- The system filter looks gray or brown and maybe should be replaced without delay
