LG LWHD1209R Filter
A changeable air filter is there for filtering out dust and other tiny bits as it is being forced through the system. This helps keep the unit clean and help it be way more efficiently while also cleaning the air breathe in and out everyday. Because of the nature of filtering air, this filter should really be swapped out for a new one or perhaps cleaned thoroughly at least twice a year if not more, in order to keep things clean.
Signs of a poor air filter
- The air filter looks bad and perhaps should be replaced today
- When you face it toward a light, the light cannot break through to the other side of the dirt filled filter
- Many pros have recommended to switch out the air filter in your unit about every three months to keep the unit running efficiently
