Frigidaire FAS185J2A3 Filter
The filter has the main responsibility for filtering tiny dust fragments and other unwanted bits as it is being forced through the system. This helps keep the unit dust-free and make it work way more efficiently while, at the same time, filtering the air you breathe in your house. Because of this, the unit filter must be replaced or simply cleaned a few times a year depending on how much you use it.
Major clues the primary air filter is failing
- With a light behind the air filter, the light will not shine through to the other side of a very dirty air filter
- The system filter looks bad and could be replaced ASAP
- It is highly suggested to swap out your air filter every 90 days for clean air inside the house
