A changeable air filter is responsible for trapping really small dust parts and other miniscule particles as it is being forced through the system. The filter can both keep the unit clean and make it run more efficient while also cleaning the air you breathe in your house. During regular maintenance the unit filter must be exchanged or possible scrubbed clean at least twice a year if not more, depending on how much you use it.
Subtle cues of a laboring main filter
- The unit air filter looks gray or brown and replacing it would be best ASAP
- If you were to lift up the filter, the light will not shine through a very dirty air filter
- Many pros have recommended to replace the filter every season of the year to help keep the air fresh and make the unit run more efficient
