LG LW1800ERZ3 Filter
The filter is there for removing small dust molecules and other tiny particles as it passes through. This simple filter can protect the unit and help it be way more efficiently while also cleaning the air you breathe in your house. Because it is really easy to do, the unit filter must be changed out or possible scrubbed clean periodically in order to keep things clean.
What to see if the air filter is almost full?
- Professionals have advised to swap out your air filter every 90 days in order to have cleaner breathable air inside
- As you face it toward a light source, it does not shine on the opposite side of a dirty filter
- The filter looks dirty and it would be best to replace it before tomorrow
