Frigidaire CRA103BT12 Filter
The air filter is there for trapping really small dust parts and other miniscule particles as it is being forced through the system. The filter can both help keep the wall unit from building up too much dust and make it run way more efficiently while also filtering the air in your home. During regular maintenance it should be simply replaced or perhaps washed a few times a year depending on how much you use it.
Key symptoms of a weak dust filter
- It is highly recommended to switch out the air filter in your unit every season of the year to keep the house clean and less dusty
- If you hold it up to the light, it will barely permeate to the other side of a completely clogged filter
- The air filter looks gross and it would be a good idea to replace it immediately
