LG LSN120HE Filter
The filter is responsible for removing small dust molecules and other particles as it is being forced through the system. This simple filter can keep the unit dust-free and help it be more efficient while, at the same time, filtering the air in your home. Because of the nature of filtering air, the air filter must be swapped out for a new one or perhaps washed at least twice a year if not more, in order to keep things clean.
Important clues of a faulty primary air filter
- It is greatly recommended to replace your air filter every 90 days in order to have clean air in the home
- The system filter looks gross and it would be best to replace it soon
- As you face it toward a light source, it will almost not penetrate through a dirty filter
