Frigidaire LRA074AT70 Filter
The filter in the wall unit is the best line of defense when removing microscopic dust and other small elements from the air in the house. The filter can both keep the unit clean and help it be more efficient while also cleaning the air you breathe. Because of the nature of filtering air, it should be swapped out for a new one or cleaned every so often depending on how much you use it.
What are the indications that my air filter really needs to be replaced?
- It is highly recommended to replace the filter about every three months to help purify the air indoors
- Sunlight does not shine on the opposite side of the filter at all
- The main filter looks dirty and must be replaced real soon
