LG LW1215HR Filter
The air filter is good at filtering minute dust particles and other particles as it is being forced through the system. This filtering system will help keep the wall unit from building up too much dust and make it work more efficient while cleaning the air in your home. During regular maintenance this filter should really be exchanged or perhaps washed every so often in order to keep things clean.
Major warnings of a declining dust filter
- Sunlight will barely infiltrate to the opposite side of a clogged air filter
- It is suggested to swap out your air filter every 90 days to help prevent bacteria from spreading too much
- The system filter looks dirty and probably should be replaced right away
