LG LSN090HE Filter
A changeable air filter has a main job of trapping really small dust parts and other particles as it passes through. This filtering system will help keep the wall unit from building up too much dust and help it be more efficient while cleaning the dust out of the air you breathe all day. Because of the nature of filtering air, the air filter must be simply replaced or simply cleaned periodically in order to keep things clean.
What signals that my primary air filter is about to stop working?
- Many pros have advised to switch out the air filter in your unit every three months so as to have cleaner breathable air
- The main filter looks gray or brown and replacing it would be best without delay
- If you place a light source behind it, the light is unable to show on the other side a clogged air filter
