Frigidaire FAM157R1A2 Filter
The filter in the wall unit is good at filtering tiny dust fragments and other tiny bits from the inside air inside the home. The filter can both keep the unit dust-free and help it be a lot better at doing its job while also cleaning the air you breathe in your house. During regular maintenance the filter should be exchanged or cleaned a few times a year in order to keep things clean.
Red flags the primary air filter is in dire need of a replacement
- As you face it toward a light source, it will hardly penetrate through a very dirty air filter
- The system filter looks dusty and it would be best to replace it as soon as humanly possible
- It is advised to swap out your air filter every 90 days for clean air inside the house
