Frigidaire FAH12ES2TA Filter
The filter in the wall unit is there for removing small dust molecules and other tiny bits 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 operate way more efficiently while also cleaning the air breathe in and out everyday. During regular maintenance this filter should really be replaced or perhaps washed at least twice a year if not more, in order to keep things clean.
Major symptoms of an ineffective primary air filter
- It is suggested to replace your air filter about every 90 days to keep the unit running efficiently
- If you were to lift up the filter, the light is unable to infiltrate to the opposite side of a dirty filter
- The main air filter looks dirty and congested badly
