Frigidaire LRA107BU115 Filter
The unit filter has the basic duty of removing small dust molecules and other small elements from the air in the house. This simple filter can keep the unit dust-free and help it be much more efficient while also filtering the air you breathe in your house. Because of this, the unit filter must be changed out or cleaned at least twice a year if not more, in order to keep things clean.
Red flags of an inadequate main filter
- If you place a light source behind it, the light will hardly breach the other side of a dirty filter
- It is highly advised to switch out the air filter in your unit every 90 days to help prevent bacteria from spreading too much
- The system air filter looks like it is filled with dust and the best thing to do would be to replace it soon
