Frigidaire FAX050S7AB Filter
The filter was designed for filtering minute dust particles 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 work a lot better at doing its job while also cleaning the air you breathe in your house. Due to the fact that this is an important part of the system, the filter should be exchanged or cleaned at least twice a year if not more, in order to keep things clean.
What warnings should I watch out for to know if my primary air filter really needs to be replaced?
- The system filter looks gray or brown and probably should be replaced ASAP
- Professionals have recommended to replace your air filter about every three months in order to have clean air running through the unit
- If you lift the air filter up to a source of bright light, the light will barely shine through a dirt-packed filter
