LG LP073CD2A Filter
The filter in the wall unit is good at trapping really small dust parts and other particles from the air in the house. This filtering system will help keep the unit dust-free and make it work much more efficient while cleaning the air you breathe in your house. Due to the amount of dust in the house, this filter should really be replaced or simply cleaned every so often depending on how much you use it.
Major warnings the primary air filter probably needs to be replaced
- With a light behind the air filter, the light will hardly shine on the opposite side of the air filter
- Professionals have suggested to switch out the air filter in your unit every season of the year to help clean the indoor air
- The system air filter looks gray or brown and probably should be replaced as soon as you can
