Frigidaire LRA18HMT20 Filter
A changeable air filter has a main job of filtering tiny dust fragments and other tiny bits from the inside air inside the home. This simple filter can make the unit cleaner and make it work more efficient while also cleaning the air in your home. Because of the nature of filtering air, the filter should probably be simply replaced or simply cleaned at least twice a year if not more, in order to keep things clean.
Major indications of a faulty primary air filter
- The air filter looks like it is filled with dust and the best thing to do would be to replace it immediately
- It is highly suggested to switch out the air filter in your unit every three months to keep the air inside clean and free of harmful dust
- Sunlight will not shine on the opposite side of the dirt filled filter
