Frigidaire CRA086AT712 Filter
The filter has a main job of trapping really small dust parts and other particles as it passes through. The filter can both help keep the wall unit from building up too much dust and make it operate more efficient while also cleaning the dust out of the air you breathe all day. Due to the amount of dust in the house, this filter should really be simply replaced or perhaps washed at least twice a year if not more, in order to keep things clean.
Simple indications of a bad main filter
- Professionals have advised to switch out the air filter in your unit about every 90 days to keep the air inside clean and free of harmful dust
- The air filter looks gray or brown and could be replaced before tomorrow
- If you hold it up to the light, it will almost not break through to the other side of a very dirty air filter
