LG L1404R Filter
The filter was created for filtering out dust and other tiny bits as it is being forced through the system. This filtering system will help keep the unit clean and make it operate more efficient while also filtering the air breathe in and out everyday. Due to the amount of dust in the house, this filter should really be changed out or cleaned periodically in order to keep things clean.
Signs of an ineffective primary air filter
- When you face it toward a light, the light will almost not show on the other side the dirt filled filter
- The filter looks very bad and perhaps should be replaced without delay
- It is highly suggested to switch out the air filter in your unit about every three months in order to have clean air in the home
