Frigidaire CRA074AT71 Filter
The unit filter is responsible for removing microscopic dust and other small elements as it is being forced through the system. The filter can both keep the unit clean and help it be more efficient while, at the same time, filtering the air in your home. Because of the nature of filtering air, it should be swapped out for a new one or cleaned a few times a year depending on how much you use it.
Key signs of a bad primary air filter
- When you hold it up, the light does not permeate to the other side of a completely clogged filter
- It is suggested to replace the filter every season of the year to keep the air inside clean and free of harmful dust
- The unit air filter looks brown and replacing it would be best immediately
