A changeable air filter has a main job of filtering tiny dust fragments and other particles from the air in the house. This simple filter can protect the unit and make it operate more efficient while also cleaning the dust out of the air you breathe all day. During regular maintenance the filter should be replaced or simply cleaned every so often depending on how much you use it.
General warnings of a defective primary air filter
- Manufacturers have recommended to replace the filter about every 90 days to assist in keeping the indoor air clean and fresh
- If you lift the air filter up to a source of bright light, the light does not breach the other side of a dirty filter
- The air filter looks bad and could be replaced as soon as you can
