LG LAN091CNP Filter
The filter was created for trapping really small dust parts and other tiny bits from the air in the house. This can both help keep the wall unit from building up too much dust and make it work much more efficient while, at the same time, filtering the dust out of the air you breathe all day. Due to the fact that this is an important part of the system, the air filter must be exchanged or cleaned at least twice a year if not more, depending on how much you use it.
Important signs your main filter is in dire straights
- The system air filter looks brown and it would be best to replace it before tomorrow
- Manufacturers have advised to switch out the air filter in your unit about every three months to help purify the air indoors
- If you were to lift up the filter, the light cannot permeate to the other side of a very dirty air filter
