LG LS180HE Filter
The filter in the wall unit has the basic duty of filtering tiny dust fragments and other tiny bits as it is being forced through the system. This helps help keep the wall unit from building up too much dust and make it run more efficient while also filtering the air in your home. During regular maintenance this filter should really be simply replaced or simply cleaned at least twice a year if not more, depending on how much you use it.
Some warnings the primary air filter will soon need to be replaced
- If you hold it up to the light, it will almost not permeate to the other side of the filter
- It is suggested to swap out your air filter every 90 days to help keep the air fresh and make the unit run more efficient
- The filter looks brown and must be replaced right away
