LG LA090CP Filter
The filter in the wall unit was designed for trapping really small dust parts and other particles from the inside air inside the home. This helps help keep the wall unit from building up too much dust and make it work a lot better at doing its job while, at the same time, filtering the air in your home. Because of this, the filter should probably be simply replaced or cleaned at least twice a year if not more, depending on how much you use it.
What are the indications that my primary air filter is not doing its job?
- If you were to lift up the filter, the light will hardly shine through to the other side of the filter
- It is recommended to switch out the air filter in your unit about every 90 days for clean air inside the house
- The system filter looks gross and should be replaced now
