LG LA120CP Filter
A changeable air filter has the basic duty of removing small dust molecules and other small elements as it is being forced through the system. This simple filter can help keep the wall unit from building up too much dust and make it work more efficient while also cleaning the air in your home. During regular maintenance the air filter must be exchanged or cleaned every so often in order to keep things clean.
Major symptoms the air filter will eventually need to be replaced
- It is highly advised to replace the filter about every three months to help keep the air fresh and make the unit run more efficient
- The unit air filter looks bad and perhaps should be replaced ASAP
- When you hold it up, the light is unable to shine through the dirt filled filter
