Frigidaire FAM187Q2A4 Filter
The unit filter was designed for removing microscopic dust and other tiny particles as it is being forced through the system. This simple filter can help keep the wall unit from building up too much dust and make it run more efficient while also cleaning the dust out of the air you breathe all day. During regular maintenance it should be simply replaced or cleaned at least twice a year if not more, in order to keep things clean.
Major warnings of a defective air filter
- The unit air filter looks like it is filled with dust and maybe should be replaced as soon as you can
- It is greatly suggested to swap out your air filter every three months to help clean the indoor air
- When you hold it up, the light will barely shine through a very dirty air filter
