Frigidaire FAS25ET2A11 Filter
A changeable air filter is designed to be good at filtering tiny dust fragments and other tiny particles from the air in the house. The filter can both keep the unit clean and make it operate way more efficiently while, at the same time, filtering the air you breathe in your house. Due to the amount of dust in the house, it should be swapped out for a new one or simply cleaned every so often depending on how much you use it.
Simple signals your main filter will have to be replaced
- Filter appears dirty and crammed with dust completely
- It is suggested to replace your air filter every 90 days to help keep the air fresh and make the unit run more efficient
- If you place a light source behind it, the light is unable to penetrate through a dirty filter
