LG LSU120CE Filter
The filter has the basic duty of filtering minute dust particles and other particles as it is being forced through the system. This can both help keep the wall unit from building up too much dust and make it run much more efficient while cleaning the air breathe in and out everyday. Because of this, the unit filter must be simply replaced or possible scrubbed clean periodically in order to keep things clean.
Simple indications of a deteriorating air filter
- When you face it toward a light, the light does not show on the other side a dirt-packed filter
- The filter looks bad and the best thing to do would be to replace it as soon as humanly possible
- Professionals have suggested to replace your air filter about every 90 days to help prevent mold and bacteria build-up
