LG LSN122CE Filter
A changeable air filter was designed for filtering tiny dust fragments and other miniscule particles as it passes through. The filter can both help keep the wall unit from building up too much dust and make it run a lot better at doing its job while cleaning the air you breathe. Because of this, it should be changed out or simply cleaned at least twice a year if not more, depending on how much you use it.
Major indications the primary air filter is in dire need of a replacement
- The system filter looks bad and replacing it would be best before tomorrow
- When you hold it up, the light will not shine through a dirty filter
- Professionals have suggested to switch out the air filter in your unit four times a year in order to have cleaner breathable air inside
