LG LSN305HV Filter
A changeable air filter is there for filtering tiny dust fragments and other tiny bits as it is being forced through the system. This filtering system will help keep the wall unit from building up too much dust and make it operate way more efficiently while also filtering the dust out of the air you breathe all day. Due to the fact that this is an important part of the system, this filter should really be exchanged or simply cleaned a few times a year depending on how much you use it.
Some clues to an under performing primary air filter
- The main filter looks very bad and the best thing to do would be to replace it as soon as you can
- If you hold it up to the light, it is unable to penetrate through the air filter
- It is suggested to replace the filter about every 90 days to keep the house clean and less dusty
