Frigidaire FRA186MT2 Filter
The filter in the wall unit is the best line of defense when removing small dust molecules and other miniscule particles from the air in the house. The filter can both help keep the wall unit from building up too much dust and make it work way more efficiently while, at the same time, filtering the air in your home. Because of this, the air filter must be simply replaced or perhaps cleaned thoroughly at least twice a year if not more, depending on how much you use it.
Major symptoms of a weak main filter
- It is greatly advised to switch out the air filter in your unit every three months to help keep the air fresh and make the unit run more efficient
- If you lift the air filter up to a source of bright light, the light is unable to penetrate through a dirty filter
- The main filter looks like it is filled with dust and probably should be replaced without delay
