LG LSN242HE Filter
The filter has the main responsibility for filtering minute dust particles and other tiny particles from the inside air inside the home. This can both protect the unit and make it operate way more efficiently while, at the same time, filtering the air you breathe. Due to the fact that this is an important part of the system, it should be replaced or perhaps cleaned thoroughly every so often depending on how much you use it.
Clues to watch for to know the primary air filter will soon need to be replaced
- If you hold it up to the light, it cannot break through to the other side of the filter at all
- The filter looks gray or brown and it would be a good idea to replace it right away
- It is suggested to replace the filter about every 90 days so as to have cleaner breathable air
