Frigidaire FRA086AT7 Filter
The filter in the wall unit is the best line of defense when trapping really small dust parts and other tiny bits as it passes through. This simple filter can help keep the wall unit from building up too much dust and make it work more efficient while cleaning the air you breathe in your house. During regular maintenance the filter should be replaced or perhaps washed periodically in order to keep things clean.
How do you know when your main filter is not working properly?
- Many pros have suggested to swap out your air filter every three months to keep the air inside clean and free of harmful dust
- As you face it toward a light source, it will hardly shine through to the other side of a completely clogged filter
- The system air filter looks gross and must be replaced real soon
